I'm not sure of how this works exactly, are HL and DE
HL = HL + BC + 1
DE = DE + BC + 1

or, is it
DE = DE + BC

I just need to know to see if I should increment DE before using LDIR again Smile
HL = HL + 1
DE = DE + 1
BC = BC - 1
I think you mean DE/HL + BC vs. DE/HL + BC - 1, don't you? ldir effectively does the following (without trashing the accumulator, obviously):
    ld a,(hl)
    ld (de),a
    inc hl
    inc de
    dec bc
    ld a,b
    or c
    jr nz,ldir
Ah yes, that's what I meant. So it would be DE/HL+ BC. Thank you!
