I just had another look at the code and I can only think that this will work with a code generator. If you enter this code into an assembler, it will complain that 'timer_b1', 'timer_b2' etc is a long address and can't fit to word. I also tried move.w #timer_b1&ffff,$122.w but this just generated code that had the label's address at assembly time (at least in Turbo Assembler), so again it's useless. With a code generator you can bypass all these problems and just write down the addresses by yourself :).
Also another small point: you actually need to point to #timer_b1+2, #timer_b2+2 etc for this to work on any other 64 page than the first, otherwise you'd be just writing the high word of the address over and over :).
(yes I know that all the above are pretty much apparent, but I'm just writing this to keep me awake! Really nice cycle crunching, Defjam :)).

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
