Baseball Stars ROM Hacking
Make Baseball Stars on the NES your own: edit every team and player, lineups, hires, uniforms and colors, plus new money, create a team and a randomizer.
About this release
This is a work in progress. Load your own Baseball Stars (USA) NES ROM and make it yours. Classic - Lite edits only what shipped in the game: rename every team and player, change their stats, faces, batting stances, boys and girls, the lineups, the players you can hire and what they cost, and the colors of the uniforms and screens. You can even load your save file and edit the teams you made in the game. Enhanced adds features the game never had: a new money system, create your own team, and a randomizer, with more on the way. Try it right away with Play it now, then save a BPS patch or a ready-to-play ROM. Your ROM stays in your browser and is never uploaded. Please report bugs on the Suggest and Report tab.
How to use it
Click "Open the tool", load your Baseball Stars (USA) .nes file, pick Classic - Lite or Enhanced at the top, make your changes, then use Play it now or save your ROM or BPS patch. It runs right in your browser, with nothing to install.
