Batch analysis of all 273 profiles to identify HLE/embedded fallbacks. Added hle_fallback: true where the core has verified software replacement for missing BIOS files: - Embedded ROMs: vice (102), ep128emu (22), fuse (18), frodo (4) - HLE BIOS: bsnes* (33 across 3 profiles), puae (9 AROS), noods (4), melonds* (6 FreeBIOS), flycast (3 reios) - Open-source replacements: sameboy (8), pokemini (1), gpsp (1) - Built-in fallbacks: np2kai (7), atari800 (6 Altirra), picodrive (3), quasi88 (4), gambatte (2) Conservative: only added where notes or source code confirm HLE. Skipped 50+ profiles where files are optional alternatives, not HLE replaceable (neocd, opera, kronos, pcem, etc.)

|
|
Xemu is a free, open-source Xbox emulator based on QEMU.
|
|
Three firmware files are required for operation: MCPX boot ROM,
|
|
flash ROM (BIOS), and EEPROM image. A pre-built HDD image is
|
|
also needed. The EEPROM can be auto-generated by xemu if not
|
|
provided. Config stored in xemu.toml under sys.files section.

|
|
notes: |
|
|
Overlaid on the last 512 bytes of the flash ROM region at boot.
|
|
Mapped to 0xFFFFFE00-0xFFFFFFFF. Disabled after early init
|
|
via LPC config register write (hw/xbox/xbox_pci.c:362).
