Feature Request: A couple of things can be added so when outputed asm is compiled in asar it can auto remap all pointers and jumps after adding or removing asm and auto add empty data

[slidelljohn]

Here is a modification that I have to make to the outputted disassembly in order for all pointers and jumps to auto remap in asar after adding or removing asm:

I have to manually add this label "LDX.W #CODE_0081C9" that points to where high score data is in Gradius 3:

There is a few modifications that I have to make for empty space to automatically be calculated:

1. Manually remove empty space "0xff..............". Last empty byte removed = $00FFBF
2. Add starting point for data/asm after manually remove empty space = ORG $00FFC0
3. Add fill byte code to beginning of asm file so all empty space is 0xFF.
   

I have seen some roms have set patterns for empty space that can be multiple bytes but Im not sure what the limitations of "fillbyte" is in asar.

Having DiztinGUIsh set that label is the most important issue. Having the empty space to automatically be calculated/added might or might not be something that can be useful. I would like to hear others opinions on the empty space part.

sorry this reply is months later,

1. on the label, I see what's going on, I think.

It's loading literally the number "#$81C9" as a constant.
Diz currently doesn't have a good way to infer that the number 81C9 really means the same as the label at address 0081C9.
This is something I've been wanting to add but, getting it right in all possible cases is tricky.
We need a way to manually override things with labels where a human can tell Diz, hey this is what this really means, just type it in there for me.

vaguely same kind of thing going on with #101 and #100

2. on the other stuff, what I like to do is,

export all the stuff from Diz in a directory called export/

make a new main.asm file in your root dir that is only hand edited (never genrated), then do something like:

; include everything from Diz first so you start with the original ROM
incsrc "export/main.asm"

; now, do things that override / modify the original rom:
org $008000
fillbyte $FF
fill $8000

use a commandline like:

asar.exe main.asm
