I did end up creating a backup account on programming.dev but I’m glad SDF is back! Any word on what happened?

I’ve been working on a multi-ROM, a hybrid multi-system cartridge/disk image. Mostly got DOS+MBR working except something is still going wrong in my BIOS disk reading code. The read succeeds, but the system hangs when the function returns. Really want to get that sorted because I want to get GameBoy code in there!
