Hi. I've been wondering for a long time what would be the best possible AY emulation on SAA (unfortunately 100% perfect is not possible because of chips differences). Old conversions of ZX128 games and demos were rather poor. When Tygrys/speccy.pl wrote PT3 player for ESXDOS (for ZX Spectrum) I thought I would try to write one for SAM with the best AY emulation I could get.
And here it is! My own PT3 player for SAM! There are tons of great PT3 tunes on Internet. Some more tracker formats (PT2, STC and more) can also be converted to PT3 e.g. by Vortex Tracker II for Windows.
I have also converted some ZX Spectrum demos. One of them is Signal 3 - first conversion I've seen (heard) on my SAM, 30 years ago. Old conversions of Signal 3 are also included to compare with mine.
