Ok the next stage is to get some actual code running.
I found a code sample here.
created a local file asmtest.asm
Because I created a new terminal session I need to run these two commands again.
export bB=~/Atari2600/bB export PATH=$PATH:$bB
I used this command to compile.
Joes-MBP:samples arkleyjoe$ dasm.Darwin.x86 asmtest.asm -I"$bB/includes" -f3 -lasmtest.list.txt -v5 -sasmtest.symbol.txt -oasmtest.bin
Open Stella, select asmtest.bin
Next up is to try some code I have actually written.
