Take out your modified code sections, and tell me where to put them. If people sent the whole thing, I would have many different versions, but no idea how to combine them all. // // Official Glide64 development channel: #Glide64 on EFnet // // Original author: Dave2001 (Dave2999@hotmail.com) // Other authors: Gonetz, Gugaman // //**************************************************************** // // March 2002 Created by Gonetz (Gonetz@ngs.ru) // Info about this ucode is taken from Daedalus source.
