LDA ($10),Y
I will load from a fixed address (pointer_low and pointer_high). I didn't get those labelled... so if you position of that pointer, it will corrupt some things  . I noticed this when removing code in the first half of either bank 1C or 1D... it messes up what graphics are used for the game cursor.
So yeah... some things still need to be padded if changed  .
That's basically what I was saying... you were a bit clearer about it though.
Here's a few addresses that get loaded that way, for anyone that's interested (all in bank 1D):
$A011
[these next 3 are the "New Game"/"Continue"/"Response Rate" strings]
$A253
$A25C
$A265
$A8FB
$A977
$A97F
$AC9C
Those are all the ones I got around to changing in that bank. |

Labels can be used in this case. X816 syntax supports a few wonderful features just for code like this:
LDA <myLabel
STA $10
LDA >myLabel
STA $11
LDA ($10),Y
The use of RAM addresses isn't so important, but they could also be labeled, or otherwise symboled in the source.
EDIT: It may require "LDA #<myLabel" instead. I'm not certain, since I have not tried it. But the "get low byte\high byte" features are documented.

EDIT: It may require "LDA # Yes, it requires the #. If you don't have the #, you should get a warning from the assembler (without the #, it should be interpreted as zero-page addressing). |

Even the old assembler I use (DASM) supports this < and > ... I used it in my NSF code, for example:
doend
LDA #<silence
STA sq1_posL,X
LDA #>silence
STA sq1_posH,X
JMP read.end
...
silence
hex 7F 00 C0
dc.w silence
(part of the code for the "end of track" command in my NSF, makes the track position pointer jump to an infinite silence loop  )
So if the "silence" label is at $95C2, you'll get LDA #$C2 and LDA #$95 ... quite useful ... and yep, omitting the # would make it LDA $C2 and LDA $95, zero page  |

Hey, what text editor did you use for labelling anyway? I couldn't help noticing that even the smallest ROMs disassembled produce some very big ASM files, and Notepad sucks at big files.  |

I do not know if he uses it, but I suggest TextPad. It's what I use for C, PHP, HTML, assembly, text ... EVERYTHING!

| ConTEXT is a very good freeware text editor. |

somewhat off-topic: tried both ConTEXT and TextPad.. .they are both excellent, but i happen to find i like TextPad's setup a little better. Besides, i just found a 6502.syn syntax file on some random website, so now i can do all my fun stuff in highlighted goodness  |

I'm using EditPlus, and also got syntax highlighting for 6502 (although pretty basic, but I can improve it)
Looks like this for me
But this one is shareware |
