NEW: Version 1.2, the final version, has been released, containing massive changes!

A new player character, as well as new player photos! Balance shifts! Edits to the booster pack! Corrections for typos! Corrections to the animation! Fight Ronald even harder! Everything and the kitchen sink has been added to the game, and there may even be a Pokémon from Orre in there for all I know!


Pokemon TCG: Neo

In terms of battle, Pokémon TCG Neo is a near-complete revamp of the main game. Why? Everything in this game is balanced because all of the generation 1 cards have been replaced with generation 2 cards.

Featuring your favorites from Neo Genesis to Skyridge, so many cards have been added and modified that the game’s gameplay has been substantially altered. To create a new combat experience, Pokémon, attacks, abilities, and even a few trainer cards were tweaked. If you’re looking for a TCG hack that includes brand-new Pokémon cards, go no further than the URL below.

If you aren’t looking for a new way to play the old TCG, see the instructions below.

You have to play the game anyway because I worked really hard on it for months


As previously stated, all 187 pokémon in this game have been replaced by real-life generation 2 cards. This completes the true Johto Pokedex, with a few Kanto Pokémon tossed in for good measure. The attacks and abilities of these cards either reflect their real-life equivalents, come close to them, or I overlooked them in favor of a better attack. Trainer cards have also been revised, though not to the same extent. However, Super Energy Removal is no longer available, having been replaced by Master Ball.

This game’s balance is amazing. Cards that I thought were too weak got buffs, while cards that I thought were too strong got nerfs. In general, Pokémon, particularly evolved Pokémon, became more powerful, whereas trainer cards became weaker. The focus of the games will now be on the Pokémon rather than the trainers, providing new methods to pursue!

Because 95% of the cards in this game are unique, the dialogue, trades, and text in the game have been changed to reflect this. There are now only 7 promo cards, and EVERY card in the game is accessible, so deck build to your heart’s content; no more Card Pop preventing you from obtaining important cards.

To that end, every single NPC deck has been updated. Some even employ entirely different tactics. This is also true for the auto deck machines, which I largely populated with amusing deck ideas and the boss’ decks. One small point: instead of the 3 and 6 in the base, you can earn the Imakuni? card after fighting him 2 and 4 times. Another prominent trainer, the guy who wants to steal all of your energy cards, has stopped doing so because it is inconvenient. You can now obtain a promotion just for being kind to him.

Finally, the tutorial duel has been eliminated. I’m going to assume you all know how to play the card game; thereby letting you skip the tutorial and go straight into the fun. The dialogue for learning the game has been unaltered, so use that if you must.

The Art Style

Pokemon TCG: Neo

All of the new art in this game was done by me (Cataclyptic). I wanted to have a different feel from the base game, so instead of using mostly black and white + 2 colors, I tried to make each Pokémon as colorful as possible. This is my preference, so I’m sticking to it. If you want a poster of all the sprites, it can be viewed here https://www.deviantart.com/cataclyptic/art/Pokemon-TCG-Neo-Sprites-936162337 (Spoilers for in-game cards)

Mirror (Mega)

Previous Versions

Known Bugs & Glitches

I can’t do anything about these, but all of them only minorly affect gameplay, so it’s fine. If any of you know how to fix them or what’s going on, feel free to comment below.

  • Acid’s effect to make the opponent unable to retreat does NOT work on the AI. This is actually a holdover from the base game: it doesn’t work there either. I tried to make it work by altering the AI retreat actions, but it didn’t, so the Acid effect isn’t present in my hack.
  • Dratini and Suicune are in weird places on the computer menus. This is a result of me being unable to repoint Snorlax’s Thick Fat to another pokémon, so I did some fiddling with Dratini and made it work except for in the menus.
  • Entei’s Protective Flame doesn’t show the Protect animation if successful. This is because I’m not sure how to make it do two animations at once. The effect works regardless.
  • Houndour’s Smog attack, when used by the AI, displays as Flare. Not even sure why on this one. The attacks still work regardless, but the text is shifted on the AI.
  • The AI doesn’t appear to know how to use Energy Spike and Energy Search. Not sure how this one didn’t work either, mainly because the code is unaltered from the base game. With Energy search, I think it’s because only two decks have specified targets, therefore only two decks can play the card.


Although this game is completed, there are a couple of bonus things I would like to do but don’t have the coding skills to implement them. If anyone does know how to make these happen, then please comment below.

  • Have Acid actually work.
  • Have the Teleport Effect commands be optional/ Have the Teleport commands do damage without switching if you only have 1 Pokémon / Make the AI understand that Teleport does damage. For making more attacks that do this, of course!
  • Have Blissey’s Heal ability remove 2 damage counters instead of one. I tried to make this happen and it results in HP Underflow if it removes only 1 damage counter.
  • Make Super Fang ignore Weakness and Resistance. I had plans to implement this in the game, but it just doesn’t work if the defending pokemon is weak to Super Fang- it deals twice half HP, which translates to a guaranteed KO, which isn’t remotely fair.
  • Somehow make the Wildfire code discard X cards from the top of the deck, independent of fire energies. I can think of a few cards that would be a lot more interesting if they had effects to discard say, 3 cards each time they attacked.
  • Have more than Crystal Celebi uses Shift on the AI. The AI sadly can only process 1 user of Shift (Crystal Type), I don’t know how to make it process the other 3 crystal cards.
  • Make the AI use Energy Search and Energy Spike (Energy Boost). Self-explanatory.
  • Change the set symbols. I’d love to make all the cards from this game have set symbols from their real-life sets, but for the life of me, I can’t find those graphics anywhere.
  • Change the booster packs. I’m not sure how to change the booster packs, but I want to.
