Oh, that wouldn't be very nice
This is my code for LDIR:
Code: Select all
case 0xB0: //LDIR
Write(DE, Read(HL));
DE++;
HL++;
BC--;
flags[Flags.flags.PV] = BC != 0;
flags[Flags.flags.N] = false;
flags[Flags.flags.H] = false;
if (BC != 0)
PC -= 2;
break;
edit: oh poo I found the problem, it wasn't hanging at all it was just going too slow (omg) (yes I know I'm stupid)

Does it boot past that point?

Well it stops at 00A6 approximately, where it loops back to 00A0
I tried disassembling it but the disassembler didn't eat it (maybe its too large or something?)

It's in a loop waiting for the LCD controller to return bit 7 clear.
Here's the
Listing File of the bootloader so you don't need a disassembly.

Thanx
I'll go fix my LCD lol
edit: well it gets weirder, it gets all through it but then somehow manages to get stuck at 0029

That is weird, since 0029 is a bunch of nops.

Yes I know
I'll have to look at that.. the nop code could hardly be broken since there is no code..
edit: well it's not really dead, it's alternating between something else and 0029 but that is still odd
