I am not sure why you still don't have codehandleronly.bin after all of these years included in Dolphin. It does work if you replace codehandler.bin with it. codehandleronly.bin supports about 400 codes compared to the default 231. I will link to it after I get it uploaded. There is source code available at https://github.com/FIX94/Nintendont/blob...dleronly.s.
