BLASTER variable read :D

So I’m basically learning how to program the SB16. I have done at least two floppy disk drivers, one which only reads one side of the floppy when not on an emulator, and the other doesn’t work at all on the real hardware. But I know how to do DMA… or at least knew, I’ll need to relearn it or something like that. (The floppy is the reason why you can’t use DMA 2 for Sound Blaster, IIRC.)

On top of that, there’s a main menu screen, a Level edit screen, a Gfx edit screen,  and a Sample edit screen.
