Every part of its ref names a class from the shipped app, not a file in the repository, and only the first carried the release label; the continuations were looked up in the tree. race, xendroid, zesarux and sdl2trs only needed their pin to catch up.

notes: |
|
|
RACE is a Neo Geo Pocket and Neo Geo Pocket Color emulator originally by
|
|
Judge_ (MHE), ported to GP2X by Flavor, to PSP by Akop Karapetyan, modified
|
|
by theelf, then adapted for libretro.
|
|
|
|
No external BIOS files are required. The upstream versions (GP2X, PSP) support
|
|
optional loading of NPBIOS.BIN, but the libretro port disabled it entirely
|
|
with #if 0 in race-memory.c:loadBIOS(). The comment explains: "Using a real
|
|
bios file causes nothing but issues."
|
|
|
|
The core uses a software HLE approach: a compiled-in koyote_bin RAM dump
|
|
(post-boot console state) is copied into mainram at startup, a fake SWI jump
|
|
table is built at cpurom[0xE000], and doBios() in tlcs900h.c handles 33 BIOS
|
|
functions in software. The Z80 sound CPU is emulated via cz80 or DrZ80.

|
|
note: |
|
|
loadBIOS() is wrapped in #if 0 and always returns 0 in the libretro port.
|
|
In upstream (8bitpsp/race, alekmaul/race), the function is live and loads
|
|
NPBIOS.BIN optionally, falling back to HLE if not found.
