The upstream versions (GP2X, PSP) load\nNPBIOS.BIN optionally, but the libretro port's loadBIOS() returns 0\nunconditionally, and the disabled file-reading body it once carried under\n#if 0 was removed in June 2026, so the port no longer names the file. The\ncore never queries the system directory: the only files it opens are the\nROM and the .ngf flash save in the save directory.\n\nThe core boots through a software HLE path: a compiled-in koyote_bin RAM\nsnapshot (12 KB of main RAM captured after a real BIOS has booted) is copied\ninto mainram, a fake SWI jump table is built at cpurom[0xE000], doBios() in\ntlcs900h.c answers 14 BIOS call numbers in software, and the system font\nis an embedded table in ngpBios.c. The Z80 sound CPU is emulated via cz80\nor DrZ80.\n",
