Re: Commander Keen 4 Tandy 320x200 16 color version

I've recreated the music in TNDY-Tracker and then I played it in DOSBox-VGM to create VGM files. Those files were converted to an IMF like format: 2 bytes to send to the Tandy 3-voice sound chip followed by a UINT16LE for the delay. I also get the corrupted graphics when I play it in PCem emulating ...

Other improvements include: Faster loading times, thanks to replacing Huffman compression by ZX0 compression. Disable the score...
