The demo starts but after initial credits is looped in the part of the milkyway rotation.

Hi,

what kind of settings are you using? If I remember correctly, the Nexus7 demo has some CPU speed issue in minimig, and you need to have turbo (both) and some fastRAM enabled. I'm sure the demo worked for me.

Yes, I tried with turbo=both and works correctly, thanks!.

Other curious problem with this demo occurs at gouraud donut part, the texture looks "glitching".

This was picked up by Toni Wilen's cputester.
Source/Destination register bits suffered from some confusion when an instructions that could only work with Data registers and had a bit set for address register. The result of this confusion was manifesting itself as wrong results or even writing the results into Address registers rather than Data registers.

According to @retrofun  this has been tested on MIST and resolves the said issue. https://github.com/retrofun/minimig-mist/pull/2#issuecomment-544207071
