ASM Question

You got the idea but your asm file will not work. You need instructions in your asm file and not the hex they are represented by. (there are ways to insert hex data though)

As an example a working piece of code for the assembler would be:

Code:

org $C22872
LDA #$40
STA $1969

You can repeat the org instruction to "place your assembler cursor" on an offset. If your code is one block you only need a single org instruction.
