FDS Error $20?
by on (#11568)
I keep getting error $20 emulating the FDS. A translated jap-doc I found on this website says:
"ERR.20 ‹–”F screen data differs"
Anyone have a more detailed description perhaps? :)

The disk pointer. It's a hell to get it working right. It's reading from a wrong position. I have no clue, since there's no decent docs.

I've been browsing through the Nintendulator source and trying to do the same in my emulator but with no success. Obviously I pass the disk verification test (NINTENDO-HVC string...) but then later something happens...
