It's time for another test ROM... this time, I need to see if my ADPCM-A encoder is producing good output. smkdan's demo would be perfect for this, but for some reason, I had trouble getting it running. Since the problem was on the 68K side, I decided to just rewrite the shell quickly. (The demo makes use of smkdan's Z80/M1 driver with some small changes.)

Download: http://ajworld.net/neogeodev/examples/pcmatest_dist.zip
Includes an ISO (CD testing), a ROMset, a CHD (for testing on MESS), and the source code.

If the samples turn out good, I'll release my encoder. Otherwise, I have a bit more work to do. :/

(I didn't want to just release the encoder without hardware tests, plus my output files look different from the ones in smkdan's demo... much less other people's converters/encoders.)

hardware tests be damned, I've sat on this for too long.

Source code and Windows binaries (32-bit and 64-bit)

I used your ADPCM-A-encoder for the sample in my twister-intro... works great, no problems so far! :-)
