Illegal opcodes #4

Open greyrogue opened 5 years ago

greyrogue commented 5 years ago

At least some cartridges call illegal opcodes (e.g. Moon Patrol). Just pushed a small change to allow the opcodes listed as known illegal (just waits 6 cycles and moves to the next instruction). Not sure if you want to support this or not. https://github.com/MiSTer-devel/TI-99_4A_MiSTer/commit/383f03c0beebc745c520424cca6c1ce923753cb2
