Pokemon Crystal Showdown ROM

Pokemon Crystal Showdown is a GBC ROM Hack by pquads11 based on Pokemon Crystal. It was last updated on March 20, 2025.

Description

This is a hack that tries to emulate Pokemon Showdown-style gameplay of set level 100 Pokemon, with access to every move, maxed stats, and IVs and items. 0 grinding involved.

Features

• All Pokemon are available in wild areas all at level 100. They do not have perfect stat exp, but they have perfect IVs. If you catch a Pokemon, you will need to use the item you get from Elm “stat-exp-up” on a Pokemon which maxes out its stat exp. Pokemon start with 4 of their best breeding/level-up moves, but real movesets are to be made with TMs (you get all TMs in the game after talking to mom), move tutors (in 2 unmarked houses in Cherrygrove city, the NPCs who are facing downwards) and the move reminder (in Violet city, the house with the Pidgey, lass sprite). Furthermore, all Pokemon are sorted into categories just as in Showdown (UBER>OU>UU>NU>PU). The game up until gym 1 will have PU mons which I’m sorry for anyone testing but the Pokemon are going to be limited, but it is intended that later on, they get stronger over time to correspond with the trainers. The Pokemon available up to gym 1 are as follows: MANTINE, VENOMOTH, HITMONTOP, NOCTOWL, SEAKING, MAGCARGO, SUNFLORA, CORSOLA, PARASECT, WOBUFFET, ARIADOS, BEEDRILL, BUTTEFREE, UNOWN, DELIBIRD, DITTO
• All base stats and moves have been updated, furthermore, around 45 moves have been ported UP TO GEN 7. These are all basically the “good” competitive moves, including almost all of the newer moves with good attack power, updated spikes, stealth rock, setup moves like dragon dance/calm mind, will-o-wisp, acrobatics, and even “complicated” move effects like U-turn, volt switch, foul play, brick break, sucker punch, knock off, etc. Some good newer moves however are still not in the game. As you have access to all the moves any Pokemon can learn you can see for yourself what movesets are available. If you are not sure, LOOK UP : (POKEMON) GEN 7 LEARNSET to get a good idea of what a Pokemon can learn. Without these new moves, the Gen 2 competitive play just becomes a horrid rest/curse spam fest, which I thought would be boring. Held items have also been upgraded to Gen 7, but no new ones were added. They can be bought at the Violet mart, but I intend for them to be available in every mart.
• Trainers have been massively improved. instead of fighting a ton of different trainers, this game will be more of a boss rush, of just a string of very strong trainers. These will be the gym leaders, certain other “boss” trainers, and some regular call trainers. They feature good movepools, perfect stats, held items, and an improved AI. For this test, most trainers up until red are completed but the routes and Pokemon are not yet so I have the cutoff at gym 1 where everything is completed basically. This is really the main driving feature of the game I intended. For this test, I have shortened Professor Elm and Mr. Pokemon dialogues and also shortened the first to trainer’s teams (youngster Joey and bug catcher Wade). The main trainers to beat for this test are the elder in Sprout Tower and FALKNER, no other trainers can even be interacted with right now.

Known Bugs

• SPEED UP FEATURE RECOMMENDED WHEN PLAYING! due to things like slow hp bar, as well as traveling.
• some overworld sprites are inverted due to a glitch that needs GIMP to be fixed but I just haven’t gotten around to it yet.
• various other bugs could exist without me knowing. Many of the new moves I had no other refrence to compare to so are completely made by me. As a non programmer, there might be some bugs or moves that have some effect that is not intended. if any are found please let me know. Other bugs could exist elsewhere that i am unaware of. PLEASE SAVE FREQUENTLY.
