DrSMS is a Sega Master System and GameGear Emulator that will allow you to play all of the old Sega 8-bit classics on your Gameboy Advance.
The main program is a windows-injector, used to “inject” Master System or GameGear ROMS into the provided .gba file.
PS: The illustration picture shows “Choplifter”, which is a commercial game, ripping the picture was easier to make one on our own 😉
