::That's not disassembly. Disassembly is taking the bytes and matching them to 6502 ASM. As it stands, It is little more than marking sections. I think it should include the address, the opcode, and the 6502 ASM with an explanation. Here's a fictional example with fictional opcodes: | |||

Really though, code doesn't belong completely in the ROM map, as it's useful to also list where the code gets loaded in the 6502 address space (so you can find it easily in a debugger). Think bank swapping etc. I'd suggest a Disassembly page for the game instead. ROM and RAM maps could have code sections '''marked''' but actual disasm would be lengthy and better treated on its own. --[[User:Aav|Aav]] 14:14, 7 January 2010 (UTC) | |||

- That's not disassembly. Disassembly is taking the bytes and matching them to 6502 ASM. As it stands, It is little more than marking sections. I think it should include the address, the opcode, and the 6502 ASM with an explanation. Here's a fictional example with fictional opcodes:
; Add a coin to max coins: $8000 : $08 $87 : LDX $87 ; get the current number of coins $8003 : $22 : INX ; add one $8004 : $44 $87 : STX $87 ; store the result $8006 : $78 $20 $89 : JMP $8920 ; goto the update coin text routine
