SP0250 support

[smdjeff]

Any thoughts on supporting output for the SP0250? It's very similar but with a voiced/unvoiced and fixed 15byte frame.

Thanks for checking out my project! I can take a look at this.

Cool! I have made some progress building one that does run in the SP0250 but doesn't sound great. Might be something useful there for reference in your efforts. https://github.com/smdjeff/sega-vector/blob/18e1a19cfa7e23ee0a2a3532814778675877913e/tools/wav2sega.py

Thanks for sharing! I can use that as a starting point. How are you driving/emulating the SP0250 to evaluate the quality of your output?On Feb 24, 2026, at 20:34, Jeff Mathews ***@***.***> wrote:smdjeff left a comment (tornupnegatives/TMS-Express#64) Cool!

MAME has an SP0250 emulation for several games. I've used that. But also I have a script that converts SP0250 frames to WAV. It sounds very close to MAME. So you could use that too. https://github.com/smdjeff/sega-vector/blob/main/tools/sega2wav.py
