Just for fun, I'll c/p the ReadMe file
Also, don't ask for the Pokemon Card GB2 ROM, because it's illegal to provide and will get you modded
Pokemon Trading Card Game 2: Team Great Rocket Invades! Patch Version: 0.1 BETA
How to patch: Grab your favorite patching program (I use Lunar IPS), as well as an unmodified original Japanese version (GOODGBC name Pokemon_Card_GB2_-_GR_Dan_Sanjou!_(J)_[C][!]). Once you have both, open up the program, and select Apply IPS. Select the patch (POKEMONGB2_0.1BETA.ips) and apply it to the original ROM.
Fire it up in your emulator, and enjoy.
What's done? Names. Some deck names. Some menu options. Altered Booster Pack graphics to show English names. Altered battle graphics. All cards (most Pokedex blurbs, as well). As far as I can tell, all the cards work, glitch-free.
What's to do? Dialogue. Finish Pokedex blurbs. Finish menus. Finish title screen, Card Pop! screen, and Challenge Hall graphics.
