Perhaps the best solution is to stick to the C64 documentation and avoid unstable opcodes, since they seem to cause a malfunction in the 6502 bus circuit, leading to processing undefined byte values. Esapecially if you notice that the behaviour is strongly influenced by the electrical design of the bus. -- +++ GMX - die erste Adresse für Mail, Message, More +++ Bis 31.1.: TopMail + Digicam für nur 29 EUR http://www.gmx.net/topmail ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
