Technical notes

All ROMs go under /ep128emu/roms/. The core has built-in ROM fallbacks for every file, so it works without any user-supplied ROMs. External ROMs provide byte-exact originals vs the built-in copies.

Enterprise EP128 is the default machine. EP64 is selected when content requires it. Machine type can also be forced via core options.

Hungarian and German locale ROMs are loaded automatically when content metadata indicates the locale. The IS-DOS disk system is an alternative to the standard EXDOS disk controller.
