@agowa338 I gathered as much during my read through, but the problem I have is understanding how it's used and how it works, the examples given in the obelisk guide (the one you've linked to, as well as the one I found) haven't given me much to work with on that front. The instruction I'm working with right now and that is causing me grief is specifically the indirect LDA instructions, as I can't really follow how they're intended to work
