Demo Pokémon Zero [v0.9 alpha] - FRLG enhanced remake


Developer of Pokémon Zero
Pokémon Zero
Version 0.9 (Alpha)
Made using Pokémon Essentials 17.1


Extract the game files into a new folder rather than overwriting the old files.

If you're updating from a previous version of the game, make sure the character in your save file is not in any of the following locations:
  • Viridian Forest.
  • Alola Biodome.
  • The Silph Co. elevator.
  • Cerulean Cave, or right in front of its exit.
  • In the sea around any of the Sevii Island ports.
  • One Island.
This game should only be available at pokecommunity.com or reliccastle.com.

Important note for those updating to v0.8+ from a previous version
Version 0.8 is a one-way update of Pokémon Zero from earlier versions and brings about many changes, including a big change to the level curve. This is mostly a level increase across the entire game—particularly in the post-game—to account for the additional experience granted by the Exp. Share. The update also changes all previous Generation VII TMs into Generation VIII ones.

Updating the game to v0.8 and saving the game will bring about changes that are not backwards compatible, so please do not attempt to then go back to v0.7 or weirdness may occur. Create a backup of your save file (usually at C:\Users\[your name]\Saved Games\Pokemon Zero\Game.rxdata) if you are unsure about updating.

See the changelog below for a full list of changes to v0.8.

Relive the journey of Red or Leaf from FireRed and LeafGreen, revamped with modern mechanics and enhancements. This includes Generation VIII Pokémon and moves, as well as many of the features that didn't make it into those games. Pokémon Zero also features Mega Evolutions, Fairy types, reusable TMs and the Physical/Special split. In this game, Kanto is now home to many more than the original 151 Pokémon.

Special thanks to JohtoBlaziken for his Bootleg FireRed project, which has sped up the development of Pokémon Zero substantially by allowing me to rip most of the music and some of the maps directly. Check out the project here.

There are still future updates planned for the Trainer Tower and to include the rest of the currently unavailable Pokémon. The game also needs a general layer of polish.

Please feel free to open this project in RPG Maker XP and use whatever you want in your own (free) fan games, as long as you credit me or the original author of any third-party scripts (see credits below).

Note: You can speed up the game by pressing the ALT key.

Gameplay changes
  • Slightly reworked story. Some characters play a larger role and Leaf/Red (the opposite gender of who you're playing as) is also involved.
  • Most trainers, including Gym Leaders, have updated Pokémon teams to reflect the extra Pokémon in the Extended Kanto Dex. Important battles against your Rival, Gym Leaders etc. will have harder teams than the original games, and later on they will start to use Mega Evolution.
  • Day and night cycles return and have an effect on a few things, mostly what wild Pokémon you'll encounter and some evolution methods.
  • Technical Records from Generation VIII make their appearance, and salespeople in Pokémon Centers across Kanto will sell them to you for Battle Points. They will also award you some BP for completing certain tasks.
  • The Key Stone, required to initiate Mega Evolution, will be given to you during the story. You will also be able to find or purchase all Mega Stones except for Diancite during your adventure.
  • The Exp. Share, which functions as it does in Generation VII, will be given to you when you receive the Pokédex.
  • You can play Voltorb Flip at the Game Corner for Coins instead of the slot machines, if you so wish.
  • Fight in battles reminiscent of Pokémon Yellow against Team Rocket at various points in the story.
  • Beating Blaine's Gym will get you the National Pokédex.
  • Taking a feature from Sword and Shield, there is now a man by the PC in every Pokémon Center, who acts as a Name Rater, Move Relearner and Move Deleter all in one. Relearning moves is now free, and can remind a Pokémon of level-up moves and its initial egg or event moves.
  • Tackle the Gyms in any order you please, except for the last one.

Pokémon availability
  • The Extended Kanto Pokédex contains 384 Pokémon, almost all of which are available before the Elite Four. This includes every Pokémon in the original Kanto and Johto Pokédexes, as well as every Pokémon related to them by evolution, plus a few more from Hoenn and Sinnoh.
  • Many, many more Pokémon outside of the Extended Kanto Pokédex are available as well during the later stages of the game.
  • Alternate forms for every Pokémon in the Extended Kanto Pokédex are included. This includes Mega Evolutions and Alolan Forms.
  • Meltan and Melmetal are part of the Extended Kanto Pokédex. Meltan is given away by a man near the Viridian City Poké Mart. To evolve it, speak to the girl in the Fuchsia Safari Zone entrance building.
  • Alolan Forms are catchable in a special area in the Safari Zone. This area also allows Pikachu, Exeggcute and Cubone to evolve into their Alolan Form evolutions under the right conditions.
  • The Safari Zone is now just a normal area where you can catch Pokémon without having to play the Safari Game, much like in ORAS.
  • The special magnetic field required to evolve Magneton is located in the Power Plant.
  • The Moss Rock required to evolve Eevee into Leafeon is located in Viridian Forest.
  • The Ice Rock required to evolve Eevee into Glaceon is located in Seafoam Island 1F.
  • As in Generation VIII, Eevee can now evolve into Leafeon with a Leaf Stone and Glaceon with an Ice Stone, and Pokémon that evolve via special magnetic field such as Magneton can now be evolved with a Thunder Stone.
  • Affection (which is different to friendship) does not exist. Eevee will instead evolve into Sylveon at high friendship while knowing a Fairy-type move. This takes priority over the evolution requirements for Espeon and Umbreon, so if you want one of those two Pokémon, be sure that Eevee does not know a Fairy-type move when you attempt to evolve it. This does not take priority over the evolution requirements for Leafeon and Glaceon, so you will not be able to obtain Sylveon in Viridian Forest or Seafoam Islands 1F.
  • Pokémon that evolve via trading can instead be evolved by using the Link Cable item on them. Pokémon that need to hold an item and be traded to evolve can instead hold the required item while you use the Link Cable on them.
  • All evolutionary stones and the Link Cable for trade evolutions can be purchased in Celadon City.
  • Celadon City is also home to some new stalls where you can purchase Fossils and Incense to obtain even more Pokémon. The Fossil stall will have expanded stock after the Elite Four is beaten.
  • Other evolution items such as the Magmarizer can be found in the overworld.
  • The in-game trades have been altered, and now come at a fixed level as in Generation VII.
  • There are more Pokémon available as prizes in the Game Corner.
  • The Sevii Islands contain Pokémon not in the Extended Kanto Pokédex.
  • Silph Co. now has a basement level where Rotom's form can be changed.
  • A man in the Seven Island Pokémon Center sells Nectars to change Oricorio's form.

  • Journey and battle using up-to-date mechanics like the Physical/Special split, the Fairy type, Mega Evolution and Hidden Abilities. Note that Z-Moves and Dynamaxing are not implemented.
  • Pokémon have been updated to have their Sword and Shield types, level-up movepool, stats, abilities and TM/Move Tutor compatibilities. Moves have been updated to function as they do in Generation VIII. Pokémon and moves that do not exist in Sword and Shield are instead taken from Ultra Sun and Moon.
  • Inconsistencies in how Pokémon can learn certain moves are corrected. For example, in the official series the Bellsprout line can learn Leech Life via breeding but not via TM. This has been changed. This even extends to event moves such as Zoroark learning Sludge Bomb and Gengar learning Sludge Wave.
  • Mega Evolution takes place before turn order is decided, like in Generation VII.
  • Experience Points are handled as in Generation VIII: each particpating Pokémon gets the full share of Experience Points when the opponent faints, and Experience Point gain is scaled so that you receive more Experience Points for defeating higher level foes, and less for defeating lower level foes. You will receive Experience Points for capturing a Pokémon, and Trainer Pokémon no longer award 1.5x the Experience Points of an equivalent wild Pokémon.
  • Items function as in Generation VIII. The catch rates of Balls, the two stage stat boost from the X- Items and the healing potency of Potions are amongst the updates. Item prices are also largely based on Generation VIII, so Ultra Balls cost $800.
  • Wild Legendary Pokémon have three random IVs set to 31, like in Generation VII.
  • Breeding works more-or-less as in Sun and Moon. The Day-Care doesn't level up your Pokémon, and withdrawing them costs a flat $500. The only difference is with breeding Alolan Pokémon. In Sun and Moon, you'll get an Alolan Pokémon even if you breed two Kantonian Pokémon. The only way to get a Kantonian Pokémon is to have a Kantonian Pokémon of that evolutionary line hold an Everstone while breeding. However, since this game is set in Kanto, it has been implemented the other way around—even breeding two Alolan Pokémon together will result in the Kantonian form unless the Alolan Pokémon of that evolutionary line is holding an Everstone.
  • Long story short, if you want to breed an Alolan Pokémon, you'll need to have the Alolan parent be part of the same evolutionary line as the child and hold an Everstone.
  • e.g. Female Kantonian Sandshrew + Male Alolan Sandslash @Everstone = Alolan Sandshrew

Quality of life changes
  • A 2x game speed button (ALT).
  • No limit on the number of different items you can have in your bag.
  • TMs and the original FireRed/LeafGreen Move Tutors are infinite-use instead of single-use.
  • HMs are a thing of the past. The HM moves (such as Surf and Cut) are still available in-battle but do not have a field effect. A new Key Item, the Poké Summon, instead fills the role of HMs in a similar manner to Sun and Moon's Poké Ride feature.
  • The Day-Care Center on Route 5 now allows you to deposit and breed two Pokémon. The final ledge on Route 5 also has a gap in it to make the Day-Care easier to visit.
  • You can swap Pokémon into your party immediately after capture if your party is full.
  • A woman in the Celadon Pokémon Center can adjust your Pokémons' natures, for a fee.

Minor changes
  • Minor NPC text changes to reflect changes to gameplay, including proper capitalisation and renaming of some Trainer classes like the Ace Trainer.
  • Pokémon sprites have been updated to Generation V. For Pokémon beyond this generation, suitable fan works of a Generation V style have been used.
  • TMs are sold in various Marts.
  • Pokémon cries have been updated to Generation VII/VIII.
  • Badges follow the OmegaRuby and AlphaSapphire mechanics, but have no effect on your usage of HM moves. The first badge makes Pokémon up to Lv. 20 obey, then 30, then 40 etc. The eighth and final badge makes all Pokémon obey.
  • Receive a Premier Ball with every purchase of ten or more standard Poké Balls.
  • Pokémon received from in-game trades come at pre-determined levels, rather than matching the level of the traded Pokémon. This is in line with later generations.
  • There is no tutorial in the first battle with Blue.
  • Pokémon Centers have no upstairs, as there is no external trading or battling.
  • After getting the Pokédex from Oak, he gives you twenty Poké Balls instead of five. You also start with more money, in line with later generations. This is to help with the fact that there are more species of Pokémon early on.
  • You receive the Running Shoes from your mother before leaving the house.
  • Poké Marts sell items to you based on the number of Badges you have, as in later Pokémon games.
  • No Pokémon catching tutorial from the old man.
  • No Teachy TV, Fame Checker, Powder Jar or Berry Crush.
  • No profile from the girl in the Pewter City Pokémon Center.
  • The Bike Shop's new sale price for the Bicycle is $10,000,000, to reflect to new maximum money of $9,999,999.
  • The Team Rocket Grunt on Nugget Bridge only hands out one Nugget, even if you lose and re-battle him. This sidesteps what is likely a bug in FRLG.
  • The girl who trades one gender of Nidoran for the other in the Underground Path (Route 5-6) will now accept either Nidoran and trade you a Togepi in return.
  • No questionnaire in the Vermilion City Poké Mart.
  • There is no requirement to catch a certain number of Pokémon to receive rewards from Professor Oak's aides.
  • Celadon Mansion is now called Celadon Condominiums as in Generation IV.
  • The Know-It-All blackboard describes how trade evolutions can occur via the Link Cable item.
  • Vending machines have a chance for extra drinks to drop down according to the mechanics in Generation VI.
  • The Arceus type-enhancing plates can be purchased in Fuchsia City.
  • Instead of the Exp. Share, the Aide on Route 15 gives out the Lucky Egg instead.
  • A one-way teleporter has been added to Saffron Gym that takes you from Sabrina's room to the exit.
  • Hidden items on Treasure Beach and berries in the Berry Forest respawn after 24 hours have passed.
  • The boulders in Victory Road will stay on their switches once moved into place.
  • Azurill will not change gender when evolving, as in Generation VI and beyond.

Spoilery changes
  • Route 3 has the Deoxys meteors which are used to change its Forme, as in HeartGold and SoulSilver.
  • The Kanto starters that you didn't choose are gifted to you in a similar manner to their giveaways in Pokémon Yellow. You will also be given a type-enhancing item by these NPCs, regardless of whether they give you the Pokémon or not.
  • Bulbasaur and the Miracle Seed are given away by a girl in Cerulean City. She resides in the north-west of the city, in the house on the right, instead of the Berry Crush man. Unlike in Pokémon Yellow, you do not have to show her a Pokémon with high friendship.
  • Charmander and the Charcoal can be received from a man at the top of Route 24.
  • Squirtle and the Mystic Water are given away in Vermilion City by an officer in the middle of the city. Unlike in Pokémon Yellow, having the Thunder Badge is not necessary here.
  • You'll encounter Professor Birch on Route 25, and he will give you and Leaf/Red a choice of the Hoenn starter Pokémon, as well as their respective Mega Stone. Leaf will choose before you, opting for the Hoenn starter of the same type as your Kanto starter. She'll give you a bred copy of her starter later, and you'll get the final missing starter from a Egg on Five Island's Water Labyrinth.
  • Leaf/Red meets and fights you before Bill's house, after Rock Tunnel, and in Cinnabar.
  • You also team up with Leaf/Red during the Rocket takeover of Pokémon Tower.
  • Mr. Fuji will give you the Key Stone and a Mega Stone for your starter Pokémon. If you picked Charmander, Mr. Fuji will give you a choice of either Charizardite X or Charizardite Y.
  • You will team up with Blue to take on some familiar Rockets and Giovanni in Silph Co. You will then solo fight a Mewtwo holding Mewtwonite Y.
  • Entei replaces Moltres on One Island. Moltres is back on Victory Road as in Red and Blue. Suicune and Raikou reside somewhere on Islands Two and Three respectively.
  • Receive an Alola starter of your choice after beating the Elite Four.

Now updated to v0.3. This update includes all of Four Island, and over 50 new Pokémon families to catch and train!


Developer of Pokémon Zero
I'm back, and I've just uploaded a big ol' update with v0.4! Lots of new things, so see the first post's changelog for more details. The main new things are:
  • This release includes the PBS files, for those of you editing in RPG Maker XP.
  • Added Five Island content, including a bunch of new Pokémon to catch.
  • Added the oft-requested official FRLG music tracks; huge thanks to JohtoBlaziken for saving me a lot of work here.
  • Added the Berry Master's House and Garden to Route 15. You can now obtain many Berries that were unavailable before, including the EV-reducing Berries.
I've also included a swathe of bugfixes which have been brought to my attention (and some I noticed on my own). Enjoy!
Just played it through up until after Misty. Overall, I think you've got the framework for a pretty solid enhanced FRLG remake. There's some polishing that needs to be done to bring it up and beyond FRLG's standards, but it looks like you're aware of that.

Graphically, I'd like to see some more consistency with the battle scene, and maybe some respriting of the trainer sprites in a gen 4 style considering the screen size.

I think overall, if you polish it up and embrace a bit more change (slightly tweaking some of the maps here and there, adding a couple more new things and streamlining the experience a bit), you'll have probably one of the best Kanto experiences done in Essentials. It's already pretty damn close, I'd say!

Looking forward to future updates.

Played up till Vermillion City Gym. Some thoughts of my own, as well some issues I encountered:

My thoughts:
Game's very good. The eventing is flawless and I went out of my way to "catch" you in certain points, such as when helping Bill out in his house (talking to Red at different stages, those being, before talking to Bill and once he's in the machine, will make him say different things -- that's the type of attention to detail I love, and that there are more tiny pleasant surprises along the way). I know many, many of the Hidden Items in Pokémon FRLG after playing the games for so long, so it's really pleasing to see you've taken them into account as well. Let me tell ya, out of all the "Kanto remakes" I've played, yours is the most accurate when it comes to making the game feature almost flawless eventing and being a carbon copy of the originals in some aspects (in the good way), so congratulations on that. I don't know if I'll continue playing it after Surge because on the other hand, it feels like "spicy FRLG" and not unique/bold enough to make it feel like a whole new experience.

There are lots of invisible walls in these top two rows, immediately hugging the wall and in the one my character is standing on.

Had the game completely hang up on me. I'm starting to make the connection that it's got to do with the Fast Forward script because it's happened to me and others in games featuring that script. What if you reduced the Fast Forward speed a little bit? This is the game basically coughing blood because something's happening before it can catch up. That's my intuition at least.

This lady will "take BP from me" even though I just learnt Cut (costs 0 BP).

Other tiny details that may or may not have been deliberate:
  1. One of the Mt. Moon ladders will teleport you straight into a Grunt's line of sight, whereas in FRLG/the other in your game, won't as they teleport you on top of the next ladder, not on it's side. This might have been a deliberate decision, but I'll point it out in case it's not.
  2. You can step on the upper corner tiles of the PKMN Centers. I'm not sure if this was possible in the originals, but it looks a bit weird, so I'll just point it out in case you want to double check.
  3. The game is quite imbalanced. Viridian Forest with the partner trainer really breaks the game, and it seems the presence of the Exp. Share isn't really taken into account at all. It's not just Viridian Forest generating a huge power spike for you, but rather, the game doesn't seem to catch up for a long while. When I was at Nugget Bridge, the trainers had Lv10 Pokémon, but I could find wild Lv17 Pokémon just next to them. It's quite boring and not very challenging. Brock was fair, but Misty and Surge felt very hard in comparison, with some much bigger levels than every other trainer around, so I can only imagine how hard it would be for players who don't use the Exp. Share, and decide they don't want to just cheese their way through.
  4. Unown don't really do anything new, do they? Bit of a shame they are available early, then.
  5. Cut and Flash are available as free Tutor Moves. That's great, sure. Except, what a trap! They aren't actually Hidden Moves, so learning them, while free, makes no sense. They aren't needed for progression, apparently, so why are there, instead of some actually useful moves? Made me a bit mad when I wasn't able to use Cut after beating Misty, only to unlock Scyther later on.
  6. Tutor Moves (Mega Punch and Mega Kick) seem to teach these moves indefinitely. Again, this may be deliberate, but a little imbalanced. Maybe they could also consume Battle Points? Not sure.


Elite Trainer
great work! I'm looking forward to this, I like the way you wrote the versions, features or game mechanics evolutions and breeding etc. everything is so neatly designed! the alolan forms- sprites are looking awesome, can't wait to test/play this ^^ I also like the way that almost everything is like gen 7 and that we can breed alolan Pokémon the other way around^^ eg. kantonian sandshrew (f) + alolan sandshrew (m) @everstone = alolan sandshrew. That's awesome! Good job!


Developer of Pokémon Zero
Wow! Thanks for the detailed feedback. I really appreciate you spending the time to let me know these things. I'll definitely be taking these on board for future updates, as you've raised some very good points concerning the game's design.

The level curve is a big one for me. I'm well aware of the odd spikes in difficulty and have been mulling over ways to smooth it out and keep things interesting, while also not deviating too drastically from the official games. I don't want to halve Exp. gain or anything like that.


Developer of Pokémon Zero
v0.5 is here, bringing all the Six Island content along with it. Changelog on the main page goes through all the updates in more depth. Enjoy!


Developer of Pokémon Zero
Version 0.7 is out! Main features include:

  • Single Battles at the Trainer Tower are now open for business. Like the Battle Tree in USUM, your Pokémon can be any level, your foes' levels are 50, and you finish after 20 battles. More modes planned for future updates.
  • You can now buy new items including all Mega Stones at the Trainer Tower shops. Every Mega Pokémon except Diancie is now available.
  • A woman in the Celadon Pokémon Center can now adjust your Pokémons' natures, for a fee.
  • Meltan and Melmetal have been added to the Extended Kanto Pokédex. Double Iron Bash was added to the game. Meltan is given away by a man near the Viridian City Poké Mart. To evolve it, speak to the girl in the Fuchsia Safari Zone entrance building.
  • You can now buy more specialised Poké Balls on 4F of the Celadon Dept. Store.

Sturdy Ghost

Hey man love the work you are doing, not sure if you were able to find sprites for all the Gen 6+7 pokemon or if you use EBS for that matter, if not I was able to get them all made in a one-stop pack. It's just the animations and doesn't include the cries and such but please feel free to use it and pull from it what you need! Again not sure if you are running EBS or not but if you are then this is all of them!



Uruguayan Random User
I found a very small and inconsequential bug, you can check a Pokémon's entry in the Pokédex by going to the Summary Screen of a Pokémon, hitting C and then "View Pokédex", even if you haven't obtained the Pokédex yet.


Developer of Pokémon Zero
Version 0.8 is out!

It's a massive change from v0.7. All Trainers and wild encounters have been overhauled for more variety and a better levelling experience, plus there are a raft of bugfixes and Generation VIII changes. For a full list of updates, see the changelog on the front page. Enjoy!

Good catch Lunos. I didn't spot this before my last update as I mostly check the pokecommunity thread. I'll try to get a fix out for this in the next release. Thanks!
