Compile your own TPU function set. It sounds scary but actually it is
fairly easy. You can mix and match any functions from sets A and G
(well, as long as the end fits in the TPU RAM) or you can roll your
specialised functions, if you are so inclined. Your code will be
a bit larger (because you will have the TPU code in it) and you lose
the TPU RAM as RAM, but apart from that it works as the original mask.

You can use the free (as in beer) Motorola TPU assembler if you are
running DOS or Windows or TAS, the free (as in beer and as in liberty)
TPU assembler if you run some sort of Linux or any other system that
supports gcc, bison, flex and make.

I don't know where to find the Motorola assembler. TAS is available
on http://www.bendor.com.au/TAS and you can find a lot of useful info
about the TPU on http://www.eslave.net.

The source code for the mask sets can be found somewhere on Freescale's
website, Motorola made them public a long time ago.
