Based on DOSBox 0.74 snapshot. MUNT MT-32 emulation added by libretro port.
Upstream DOSBox 0.74 has no MUNT — only OS-level MIDI (ALSA, CoreMIDI, Win32).
Hardware MIDI drivers removed, replaced with retro_midi_interface passthrough.
MT-32 activated via mididevice=mt32 in dosbox config section [midi].
Older MUNT version: no MT-32 v2.x ROMs, no CM-32LN support.
Both ROMs loaded by fixed filename from system directory root.

EmuSCV is an Epoch/YENO Super Cassette Vision emulator for libretro,

Libretro port of eSCV by Takeda Toshiya (Common Source Code Project),
ported to libretro by MARCONATO Maxime. Upstream source mirrored at
https://github.com/tautologico/common-src-project (src/vm/scv/).
BIOS loading in src/vm/scv/memory.cpp:initialize() (line 71-242). The core
tries multiple filenames in order: upd7801g.s01, upd7801g.bin, upd7801g.bios,

Tries filenames in order: upd7801g.s01, upd7801g.bin, upd7801g.bios,
bios.rom, bios.bin. First successful open wins. Upstream eSCV uses
only BIOS.ROM (uppercase); the libretro port renamed and added
fallback aliases.
The BIOS is read as 0x1000 (4096) bytes into the bios[] array, mapped
read-only at CPU address 0x0000-0x0FFF (UPD7801 internal ROM area).
When CHECKBIOS core option is YES or AUTO, the core computes MD5 of the
loaded data and compares against 635a978fd40db9a18ee44eff449fc126. If the
hash does not match, the BIOS is rejected (zeroed out, bios_present=false).
When CHECKBIOS is NO, any file content is accepted.
When CHECKBIOS core option is YES, the core computes MD5 of the loaded
data and compares against 635a978fd40db9a18ee44eff449fc126. If the
hash does not match, the BIOS is rejected (zeroed out,
bios_present=false). When CHECKBIOS is AUTO (default) or NO, any file
content is accepted. The log message for AUTO says "automatic (yes)"
but the code skips the check (code bug: != YES_VAL at line 80).
The font/character data is embedded within the BIOS at offset 0x200
(memory.h:163 get_font() returns bios + 0x200). No separate font ROM file.
(memory.h get_font() returns bios + 0x200). No separate font ROM file.
The core can start without BIOS (supports_no_game=true) but shows
"BIOS not found" or "Bad BIOS" on the OSD. Games will not run without it.

emux is a multi-system emulator by Sebastien Ronsse. The libretro port
renamed the boot ROM from DMG_ROM.bin (upstream, gb_mapper.c:32) to
dmg_boot.bin (libretro, gb_mapper.c:35) to match RetroArch conventions.

Boot ROM is 256 bytes (BOOTROM_SIZE in gb_mapper.h:10), mapped at 0x0000-0x00FF.

Emulates Enterprise 64/128, Videoton TVC, Amstrad CPC 464/664/6128,
and ZX Spectrum 16/48/128. All ROMs are embedded in the binary since
v1.1.0; external files override built-in data. Content type is
auto-detected and determines machine configuration and ROM selection.
Custom ROM mappings are possible via .ep128cfg config files placed in
ep128emu/config/ or next to content. The .info declares epd19hft.rom
and zt19hfnt.rom which are phantom entries never referenced in code.
The .info omits epdos16f.rom and exdos14isdos10uk.rom which are used
by the code. SDEXT, ReSID, and MIDI port features are compile-disabled
in the libretro build.
