Hi @c4ooo,
Can you be a bit more specific? AFAICT a nibble is just a set of 4 bits glued together; why don't you just shift-right by a constant of multiple of 4, or do you something else on your mind/question?
I need to shift the buffer down/up a nibble (4 bits). So something like 0xABCD -> 0x0ABCD0 The relevant instruction is RRD, it's not very fast but it seems like nothing is ever fast on z80..
You can do something like
xor a
_shiftloop:
rrd
dec hl
djnz _shiftloopMaybe inc hl, depends on the endianness of your buffer.
Thanks, will investigate later.

How do I shift a block of data down a nibble? IIRC there was an instruction that swapped nibbles or something that made this easy. The shifted data will never be >256 bytes long.
Posted on omni since it seems that all the monochrome z80 programmers have remained here.

I seemed to have the same problem a couple of days ago. Even with backup off, axe would create a backup of the file, even if a backup already existed (it wouldn't overwrite, it would create two vars of the same name). It would then revert to the second to last backup.

I've been busy with life andstuff, plus I've been doing more music than programming lately, so there's that bit 
Ohh nice, got any projects you could post about?

I made the hookshot finally layer-aware in an extremely hacky way!
Nice! Wouldn't it be easier to just have a subset of tiles that can be hit with a hook, and another set that can't be hit by a hook?

Personally I like how the enemy "decays" in the second animation.

A file doesnt have to have the same name as the .8xp file in which its contained. Ex if i send the program "TEST" from my calc to PC, TI's software will save it as "TEST.8xp". However if i rename "TEST.8xp" to anything like "Longer than 8 chars {}{}{}.8xp"; when i send it to my calc, it will still create the program "TEST" on my calc.

I can't view omnomIRC in chrome on android??? The space where it's supposed to be is so empty. Maybe its because of the small screen size though.

Here is a good list of instructions: http://clrhome.org/table/ (As well as what they do, how many memory they take up, how long they take to execute, and more  )

Can someone explain why ""0x80000000 / -1" in signed mode" should error?

Please be more specific  To quote kerm: "What are you trying to do? What did you expect to happen? (What errors did you get?) What actually happened?"
