I missed this when it was first posted. I have used my 3-bit ADPCM decoder over all Waixing VT03 games, including all suspected or obvious titles that were originally from Cube Tech, and sadly found that Waixing completely purged all ADPCM sound data except from Get Lost and Ocean Prospect, even as the code that sends the data to the ADPCM sound chip is either retained or poorly NOPed out.
