Trying to get Metal Slug 6 to run through Retroarch, and man, atomiswave emulation is eluding me with this frontend. I’ve checked the info for the flycast core, and it says all the required BIOS files are present. Have them in the dc folder in system. If I move the bios files anywhere else, it’ll tell me the BIOS is missing when I attempt to load the game. Got the rom & bios from the most recent MAME set. Contents of awbios.zip is bios0.ic23 and bios1.ic23. I have tried Metal Slug in both 7z and zip format, along with trying different video renderers. My emulator immediately crashes and sends me to the dev mode menu with DX12 & the opegl wrapper, while DX11 stutters. I get a black screen for a bit, like it’s trying to load something, then the emulator crashes.
I got the game working flawlessly first try with the same files in the standalone Flycast emulator in my Series X’s dev mode. Works with both 7z and zip. So I don’t think it’s the files
