Well, you don't need a disk file.
The Atom Suite and emulator are working like this:
- Write your game in MPAGD
- Build the game and the emulator is started
- Go to the V0.7.10\Suite Atom\Atomulator\mmc directory
- Rename the MENU file to e.g. ALIEN
- Press F12 in Atomulator, type *ALIEN and press ENTER
Now you can copy ALIEN in the ..\MMC directory, start Atomulator and type *ALIEN
There is also an autostart in AtoMMMC:
- Write your game in MPAGD
- Build the game and the emulator is started
- Go to the V0.7.10\Suite Atom\Atomulator\mmc directory
- Copy the MENU file
- Place MENU in the ...\MMC directory
- Start Atomulator and press SHIFT-F12 to run the game
A file called MENU is always executed when pressing SHIFT-F12 in Atomulator, or type *MENU
