I added an export to YM file, making it easier and more ZX Spectrum modules can be converted to SAPR and played on POKEY.

 

ivop has created a suite of programs that generate SAPR (stream of POKEY register values) files from YM, AY, SID, SNDH file

convert YM to POKEY:

ym2sapr filename.ym

lzss -6 left.sapr left.lz16
lzss -6 right.sapr right.lz16
mads -o:filename.xex asm\playlzs16-stereo.asm

Any examples of how it works out using this conversion method (ZX Spetrum -> Vortex Tracker -> Atari POKEY)?

You forgot to change songname.txt

 

After I read your PM this evening, I wrote a little converter that converts .psg to .ym and added it to saprtools. Only after I did that did I see this thread

I did two sample conversions here:

https://github.com/ivop/saprtools/tree/main/xex/ym2sapr/stereo

The two files starting with vortex-*

 

If you go up one directory level, you can also enter the mono and softbass directories to listen to how they sound on a single Pokey with either a buzzy bass, or a low CPU IRQ based softbass.

That's the original ZX Spectrum Pro Tracker 2.x file.

 

Edit2:

 

Added two more songs by MmcM. Originals were done in Pro Tracker 3. Files in the above mentioned directories, mmcm-*

Thanks. Nice stuff, in stereo. The mono and softbass version are alright too, except the bass is lacking in some areas.

Dupland is too long.

 

The ivop program requires address changes so that such long music can be loaded.
