Bsnes/higan v094 DSP rom support

Libretro Cores
#1

I’m running the latest git versions of both retroarch and the bsnes-libretro (https://gitorious.org/bsnes) core. Normal games work fine, but I’m unable to get any games that require the separate DSP ROMs to work. When attempting to load Super Mario Kart, for example, it tells me:

<SNIP>
[bSNES]: [Memory]: ID 27, Request "dsp1b.program.rom".
[bSNES]: Load BIOS.
RetroArch: Environ SYSTEM_DIRECTORY: "".
[bSNES]: Cannot find requested file: "dsp1b.program.rom" in ROM directory nor system directory.
[bSNES]: Complete load request.
[bSNES]: [Memory]: ID 28, Request "dsp1b.data.rom".
[bSNES]: Load BIOS.
RetroArch: Environ SYSTEM_DIRECTORY: "".
[bSNES]: Cannot find requested file: "dsp1b.data.rom" in ROM directory nor system directory.

However, I do have the ROMs that, as far as I’m aware, I should need:

ls *.rom
cx4.rom   dsp1b.rom  dsp3.rom  st010.rom  st018.rom
dsp1.rom  dsp2.rom   dsp4.rom  st011.rom

I see that it’s wanting dsp1b.program.rom and dsp1b.data.rom, but I don’t know what those are from,

Any ideas?

You have to split the DSP roms like bsnes/higan do:

dsp2.data.rom dsp2.program.rom

You can load the game with DSP rom in higan standalone and it will split them for you, search at your Super Famicom folder.
