Question here is what instructions are missing I don't think that the Amiga ran an entirely different
68K instruction set. Yes may be the instruction coverage may be different but in practice most sequences are going to be covered. Also there are several 68K cores so the question is also which one. Yep I know the other question is who fixes it all ??? By the sounds of things some one feels volunteered ? Either way who knows what needs to be fixed ?! Also Pete is right software and FPGA programming is different we appreciate that !

Not sure what you mean. In case you are thinking about rewriting QL software so it avoids misimplemented CPU instructions, that would require knowing all CPU instructions which are still affected. I can't tell yet, otherwise I would probably have fixed them. In case you are thinking about hiring someone to design a better CPU, I'm not sure if software developers are the ones to ask. This is not software, it's hardware design. I'm sure folks like Daniele, Richard and Marcel know a lot about 68K instructions, but it seems unlikely one of them would also like to learn chip design. Many people misinterpret the fact that the logic cells and connections within an FPGA can be reprogrammed. They think some emulation would take place. But there are real logic cells and real wires just like in a fixed 68K IC. The integrated circuit design process has very little in common with writing software.
