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. // // To add new combine modes: // * You MUST include an example of something that uses it // * You MUST write down the names of the GCCMUX_ things // (see combine.cpp for details) // // You may create, modify, steal, use in another plugin, or do whatever you want with this code, but you MUST credit people for their work, and not claim it as your own. // Neither I, nor anyone who is working with me, take ANY responsibility for your actions or if this program causes harm to anything, including you and your computer, in any way, physically or mentally. // // Official Glide64 development channel: #Glide64 on DALnet // // Original author: Dave2001 (aka.
