IGN
Is it worth mentioning something about the unofficial IGN instructions on the 6502 and the IGN websites? Or should we give the unofficial instruction terminology a little more time to settle? --Eighty5cacao (talk) 00:19, 2 January 2014 (UTC)
- I'm aware of the old "can't spell ignorance without IGN" joke. But you're right that some of these unofficial instructions' opcodes are hastily chosen. For example, I recently renamed a bunch of opcodes that are called KIL or JAM in certain documents to STP, which matches the official mnemonic used in WDC's 65816 datasheet for an instruction with the same semantics (halt until reset). If anything, these 2- and 3-byte NOPs with non-immediate addressing modes are similar in semantics to "anticipatory load" opcodes on other architectures, so the mnemonic should probably allude to those. PREFETCH on x86 is probably too long to be a good example though. --Tepples (talk) 05:40, 2 January 2014 (UTC)
