Past few days been working on an 8xk disassembler. So far i only have one that will take an 8xk and turn it into the bin files of its pages , for example it turns Axe.8xk into page1.bin and page2.bin. Now to work on parsing the app header ( I really dont want to do this and its a miracle I got this far, pls someone else write this ).
An exe and source is available here but not approved yet.
Edit : I realized i don't actually know how long it'll take for the file to get approved so I am posting the current source code here for now.
