RAINE

RAINE emulates Arcade games, SNK Neo Geo MVS and SNK Neo Geo CD. It reads 10 files, 2 of them required: without a required file it does not start games. A required file is needed only by the machines that use it. Each file below cites the line of source code that reads it.

Technical notes

Multi-system arcade emulator by Emmanuel Anne, built on SDL2. RetroBat installs a package whose raine.exe reports 0.97.5 and carries the joystick dead zone setting added on 2025-03-15, one day before the build date, so the pin is the last commit before that build. Its hiscore.dat, command.dat and history.dat are byte for byte the ones at that commit.

emulatorlauncher runs raine.exe -n -fs 0|1 <set> from the package folder and rewrites config/raine32_sdl.cfg first: rom_dir_0 is the folder of the game, rom_dir_1 the RetroBat bios folder, neocd_bios points at bios/neocdz.zip, emudx and artwork stay under the package, and the Neo-Geo BIOS selection defaults to 25 (emulatorLauncher Generators/Raine.Generator.cs:76-142).

A set is loaded from each rom_dir in turn as <set>.zip, <set>.7z or a <set>/ folder (source/loadroms.c:258-275). Inside an archive a ROM is found by CRC32 first and by name second (source/files.c:370-403). A ROM missing from the set and its parents ends the load with a fatal error (source/loadroms.c:1302-1317). The Windows build has curl and, before giving up, offers to download a missing archive from archive.org, neogeo.zip included (source/loadroms.c:1200-1240).

Files read from the shared folder go through get_shared, which tries the current directory, then the share path, then share path config/ (source/files.c:50-95). On Windows the share path is the folder of the executable (source/raine.c:378).

Required

Section titled “Required”

neogeo.zip required for SNK Neo Geo MVS in repo BIOS ZIP

Neo-Geo BIOS set

  • Parent of every MVS set (ROMOF("neogeo") in the drivers). The board ROMs come from rom_neogeo and the 68K BIOS from the rom_bios list, picked by the [neogeo] bios index (source/neocd/neocd.c:159-161). Index 0 is sp-s2.sp1, RetroBat writes 25 by default, uni-bios_3_2.rom. The selected BIOS, sm1.sm1, 000-lo.lo and sfix.sfix are read for every MVS game, and a missing one ends the load. Members are matched by CRC32, so sp-s3.sp1 answers for asia-s3.rom.

neocd.bin required for SNK Neo Geo CD in repo

Neo-Geo CD BIOS

  • Path from [neocd] neocd_bios (source/raine.c:564). Left empty, neocd.bin then neocd.zip are looked up through get_shared. A path ending in zip is opened and its neocd.bin member read by name, anything else is read raw, 0x80000 bytes. Nothing found opens a file dialog once, then the program exits. The image is byte swapped when the word at 0x582 reads f94e and rejected unless it then reads 4ef9. RetroBat sets neocd_bios to neocdz.zip in its bios folder, which must hold a neocd.bin member.
