You need IDA Pro 5.2 and the DOL Loader and Gekko plug-in (dol.ldw and gekkops.plw). I had some trouble finding them so I uploaded the plugins to sharebee. Check the readme.txt for more information. IDA Pro 5.2 Plugins for GameCube/Wii After installing, just open the .dol file with IDA Pro and it should open without any problems.by Dteyn - Software
I found a current link for SELLoader3 on comex's site, but in case that link goes down, I've uploaded it to Sharebee: Sir_Kane's SEL Loader Plugin - SELLoader3.rar Edit: Unfortunately, it looks like the 'main.sel' files included with SM v4.0 and up have been stripped of useful info. Darn. :-/ Edit 2: I had posted a question here on how to get the DOL loading inby Dteyn - Software
