I hadn’t thought to try using disc control. I also hadn’t realized that “Restart” was a soft reset (very cool to know!). So, that ‘did’ work, and took me to the menu.
Going off my other post though, you probably can guess when I’m working towards here haha.
Is there any kind of way to start a core like this (or Sega Saturn & Sega CD) with the disc already ejected? I’m def gonna try to do the same with the N64 DD’s English BIOS, but that’s a whole other beast because of the subsystem I’d imagine.
I did (just now) create a dummy .cue/.bin with this info, and it does get me to the interal setup, though they both are booting the CD player by default.
FILE "~BIOS.bin" BINARY
TRACK 01 MODE2/2352
INDEX 01 00:00:00
Also brainstorming how I would create a .bat to force loading other versions of these things, I know, for example, there are at least 2 visually distinct PSX BIOS.
