PRG files are used as the 68k program (the equivalent of P ROMs on cartridge systems, but the content isn't byteswapped). Several games overcome the 2MiB limit by keeping a main PRG file loaded, and only swap the ones containing data like level maps, animation tables...
Note that LOGO_*.PRG files are handled differently.
- Maximum file size: 1MiB (?)
- Type code: 0
- Loadable in: 68k program DRAM ($000000~$1FFFFF)
- Banks: 1 ($000000~$1FFFFF). Range $100000~$1FFFFF is also used for 68k user RAM, system ROM operations, CD buffers, ...
