Re: Retrieving Asm Variables from an 8xp...
I know that disassemblers just return the various addresses and hex codes. That's all an ASM program is, a bunch of numbers. Unless you know the specific address where the variable is stored, there is no way to tell the difference between a variable or an instruction, because there is no difference.

I myself am a huge Commander Keen fan, and I find it dissapointing how whenever iD's history is mentioned, Commander Keen doesn't get much more that a passing remark and then they go on to mention all the (great) FPS. As for the Vtales' engine, it looks quite impressive. The heretic engine sounds li...

If you want to add A to any 2-byte register and can't destroy any other registers besides A:
Code: Select all
add a,l
ld l,a
adc a,h
sub l
ld h,a

Another good "article" about optimization is http://www.ticalc.org/pub/text/z80/z80opt.zip
It takes the examples and explanations further than most other articles.

Tasm 3.2 didn't seem to make a difference, so i figure there must be something I could do with equates or the .org thing, but I'd rater stop wasting time trying to fix my programming setup, and just deal with it. But if someone who has sucessfuly included subroutines from different files before coul...

My program is well below the 8.8k limit. I would really like to keep these routines in seperate files, it keeps everything so much more organized. Acelgoyobis and Firetrack 2 both have executable code in include files, so I don't understand what TASM has against me. And yes, all the files I am inclu...
