Could they have chosen orange, or brown, instead of magenta?

And should they have?!

All the available browns had been used up by the C64.

Seems to almost do what it needs to. The only thing left that I should've mentioned before is that it needs to RESet the LSB in HL (the data register). So whereas maybe HL=05c0h, after creating the mask, bit 6 of L needs to be cleared, giving the result HL=0580h. Does that make sense? This any good...

No loops:
ld bc,hl
dec bc
ld a,h
xor 255
and b
ld b,a
ld a,l
xor 255
and c
ld c,a
Just uses HL & BC

ld bc,hl isn't a valid z80 instruction

Nice guide! I'd just like to point out that you should save a snapshot once you have it all working, so that you don't have to 'reflash' the emulated DivIDE flash memory each time you run Fuse.

Is your code returning to BASIC? If it is, you'll need to push IY to the stack beforehand and pop it back afterwards.

Hi, I am having similar issues with exomizer. I have tried both versions of the decruncher that come with the main zip and both just don't decompress properly, fill the screen with garbage and then reset. I am passing the compressed data to HL and target memory to DE and calling the deexo function....

I know this doesn't answer your question, but have you tried Arkos Tracker 2?

But at least it's now 3 bytes smaller AND 5 t-states faster!
