BucketMouse Pocket is an emulator for the Game Boy for Windows, Mac, and Linux written in C++11 using the SDL2 library.
Release 1: Tail Cave
Other platforms coming maybe
If you have dumps of cartridge data from Game Boy or Game Boy Color games (called ROMs by the emulation community), BucketMouse can play them. For instructions and controls, consult the included readme.txt.
I said this when BlameGear came out, and it bears repeating: I do not condone downloading ROMs illegally, and I will not help you acquire games you don't own, mostly because I don't want to go to jail.
