Technical notes

M2000 is a Philips P2000T home computer emulator by Dion Olsthoorn, based on the original emulator by Marcel de Kogel (1997). The libretro port is maintained by the same author in the same repository.

All ROMs are embedded in the binary via header files: - monitor_rom (4096 bytes) and basic_nl_rom (16384 bytes) in m2000_roms.h - SAA5050 teletext font in m2000_saa5050.h

retro_init() calls InitP2000(monitor_rom, basic_nl_rom) which copies the embedded arrays into ROM memory (P2000.c:282-311). LoadFont() uses the embedded saa5050_fnt array (m2000_libretro.c:103-161). No system directory access. The standalone version loads P2000ROM.bin, BASIC.bin and Default.fnt from disk, but the libretro port embeds all three.

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
