OK, I wrote a little test program that uses the LAX instruction and tried it on my PAL VCS 2600jr. and a Supercharger. Unfortunately DASM doesn't support illegal opcodes, so I had to insert them as byte values. Can anyone modify DASM so that it accepts illegal opcodes or recommend a PC assembler that accepts them? Anyway, the demo program works on the VCS and the results were as if the LAX gets executed properly, so I would say if Thrust doesn't work, that's a problem of the emulators.
