Last versions:
v2.0 (03.2026) smk-512 with single HDI support, some music demos
v1.j (02.2026) fullscreen exit to the main window, csave
v1.i (12.2022) small bugfix for sound
v1.h (07.2021) debug mode on F11
v1.g (03.2021) fullscreen, updates for games 

Defects:
Performance issues. Try change sound options selector to 3-channels, then mix, then back.
Try adjust better speed option for each case. Sometimes just have to tune for the best fit.
In reality, there are loads of skipped interrupts, screen & sound updates, keyboard traps.
But it looks fine anyway.
