- 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
