• Source: libretro.c:874-891
• Platforms: batocera, lakka, recalbox, retroarch, retrobat, retrodeck, retropie, romm
• X68000 IPL ROM (original model). 128 KB, loaded at IPL buffer offset 0x20000. The core tries iplrom.dat first, then iplrom30.dat, iplromco.dat, iplromxv.dat in order. At least one must be present or the core fails to start.

iplrom30.dat optional in repo

• Path: keropi/iplrom30.dat
• Size: 128.0 KB
• Priority: 2
• Source: libretro.c:875
• Platforms: lakka, recalbox, retroarch, retrodeck, retropie, romm
• X68030 IPL ROM. Alternative to iplrom.dat for X68030 model emulation. Only used if iplrom.dat is not found.

iplromco.dat optional in repo

• Path: keropi/iplromco.dat
• Size: 128.0 KB
• Priority: 3
• Source: libretro.c:875
• Platforms: lakka, recalbox, retroarch, retrodeck, retropie, romm

• Platforms: batocera, lakka, recalbox, retroarch, retrobat, retrodeck, retropie, romm
• X68000 character generator ROM. 768 KB, provides the font glyphs for text display. If missing, the core falls back to cgrom.tmp (user-generated font cache). Core fails to start if neither file exists.

• Size: 768.0 KB
• Source: libretro.c:878, libretro.c:915-919
• Alternative font file, used as fallback when cgrom.dat is absent. Typically a font cache generated by the emulator itself on other platforms.
