That is correct. However, most of them will work, and the remaining few (5) can be simulated correctly by other means. > Though I'm not sure > that all undocumented opcodes are actually that important. For a CPU that is going to be used in a C64 (or vic20) they are - all of them have been found in real world code, including the unstable two. <shameless self promotion> see https://csdb.dk/release/?id=212346 </shameless self promotion> -- http://hitmen.eu http://ar.pokefinder.org http://vice-emu.sourceforge.net http://magicdisk.untergrund.net I, personally, as a Linux geek, just don't give a shit about someone using it or not.
