Embedded ROM check in sysfile_load takes priority over filesystem. Localized kernal/chargen variants (DE, FI, FR, IT, NO, SE, CH) are in the embedded list with NULL data pointers, so selecting a non-international model produces uninitialized ROM data. JiffyDOS requires True Drive Emulation enabled and a 1541/1571/1581 drive type. C64 BASIC/kernal use shared names (basic-901226-01.bin, kernal-901227-03.bin) instead of upstream c128-specific names (basic64-901226-01.bin, kernal64-901227-03.bin) to share files with the C64 core in RetroArch's shared system directory.\n",
