Another program by Calc84Maniac, this time emulating the Game Boy or Game Boy color. It requires ndless 3.1, so make sure you’ve downloaded that. All gameboy and gameboy color roms will work with this emulator.
To use this emulator, you first require his gbc4[Calcversionhere].tns program. Next, you need ndless 3.1. Finally, you need a ROM to emulate. There are three versions, gbc4touch, gbc4click, and gbc4cx.
First, install ndless (:P). Second, make a folder called GBC Games, or whatever you want it called, and place gbc4cx inside (I have a CX CAS). I name mine agbc4cx so it will be at the top of the folder. Third, download a ROM for a Gameboy Color game and rename it to have the .tns extension at the end, for example: DonkeyKongCountry.gbc.tns. Now you can send it to the folder that gbc4cx is in.
Now, run gbc4cx and it will display all of the compatible ROMs in the folder it is in.
