EmuSCV is an Epoch/YENO Super Cassette Vision emulator for libretro,
based on eSCV by Takeda Toshiya.
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,
bios.rom, bios.bin. First successful open wins.
BIOS loading in src/vm/scv/memory.cpp:initialize() (lines 74-243).
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.
