Did you still need a hand with this?

I've had a quick look at it in a hex editor at a triton rom someone sent me (will eventually disassmble it)... Most of the addresses for the tables of interest will be at 0x11fa8. (the addresses look repeat themselves - this is due to the fact 1 rom can have 8 configs - much like SuperH and H8 roms)

The table layouts and header info seems to be very similar to a H8 - I'd say ROM is complied from similar code that h8/superh is complied from.
