Will this tool disassemble even already edited ROMs? I see the logic behind how it works, I'm just not sure how you have it disassmble the source, that's all.

Wow. Good job. I will be able to use this well. All I could suggest is to make it a win32 App and when you reimport the code, only add zeros when you need to, not just to make 4-byte entries for the instructions, kinda like this:

C2 20 00 00 | REP #$20
A2 00 04 00 | LDX #$04
AC 84 0D 00 | LDY $0D84
F0 1F 00 00 | BEQ $1F
A0 00 86 00 | LDY #$86
8C 21 21 00 | STY $2121
A9 00 22 00 | LDA #$2200
8D 20 43 00 | STA $4320
AD 82 0D 00 | LDA $0D82
8D 22 43 00 | STA $4322
A0 00 00 00 | LDY #$00
8C 24 43 00 | STY $4324
A9 14 00 00 | LDA #$0014
8D 25 43 00 | STA $4325
8E 0B 42 00 | STX $420B
EA 00 00 00 | NOP

Becomes

C2 20 | REP #$20
A2 00 04 | LDX #$04
AC 84 0D | LDY $0D84
F0 1F | BEQ $1F
A0 00 86 | LDY #$86
8C 21 21 | STY $2121
A9 00 22 | LDA #$2200
8D 20 43 | STA $4320
AD 82 0D | LDA $0D82
8D 22 43 | STA $4322
A0 00 | LDY #$00
8C 24 43 | STY $4324
A9 14 00 | LDA #$0014
8D 25 43 | STA $4325
8E 0B 42 | STX $420B
EA | NOP

And the just repair the pointers as nessesary.

I heard a printf comment in there

Why didn't you use C++ instead of C?

Or, why not make the SMWDE, but also supply an earlier version for other ROMS called "SNDE"?
