tschak909 Posted December 19, 2023 Share Posted December 19, 2023 (edited) Hey guys, trying to use dis6502 to get enough of a Dig-Dug disassembly to add my high score code. See attached. I'm not exactly sure what weird alignment issue has happened to cause the NMI to go off into la-la land, What happened here? -Thom digdug.xex digdug.asm digdug.inc Edited December 19, 2023 by tschak909 Quote Link to comment Share on other sites More sharing options...

Rybags Posted December 21, 2023 Share Posted December 21, 2023 Can't say I've looked at the code for this game. Also, isn't there at least 2 versions - Which one are you concentrating on? Quote Link to comment Share on other sites More sharing options...

I'm honestly wondering what fundamental thing I'm missing that's causing the disassembly to be at least one byte off. -Thom Quote Link to comment Share on other sites More sharing options...
robus Posted December 21, 2023 Share Posted December 21, 2023 Is there a Mac based disassembler? I’ve got most one written for my own debugging which I could probably turn into a command line tool. Quote Link to comment Share on other sites More sharing options...
Ute Posted December 22, 2023 Share Posted December 22, 2023 Hi Thom, I didn't have time to look in to what went wrong with your version, but I got a non commented version working that assembles with MADS, and the hex matches the original. I hope this helps you out. Digdug.wrkDigdug.asmDig Dug (1984) 9-21.xex 2 Quote Link to comment Share on other sites More sharing options...
+MrFish Posted December 23, 2023 Share Posted December 23, 2023 Source code exists for this version of Dig Dug, but it's for compiling to ROM. Still might be of help. Quote Link to comment Share on other sites More sharing options...
