The Toshiba chip itself can not have SW decompression. That's by definition HW decompression. The ROM is feeding the uncompressed data to the chip which it decompresses on the fly. There is no point at this stage figuring out what it does exactly, since writing a small routine - although would consume more space - could at least get you going. So don't use the SAY command and forget about BASIC. Write a small machine code routine that sets up the parameters, perhaps an IRQ and then feeds the chip with raw uncompressed data that you obtained from the SPTK (and bitformatted appropriately). A compression can be implemented later.
