Yes, I'm learning Russian, because there're a lot of excellent Russian writers!
I've tried to involve more people at this project,
because if a lot of people will be doing a brainstorm,
in that case our chances are rising!
There're a lot of professionals at this wasm.ru forum!
And they already have some results!
My player can play Rockchip games, but only these:
"Tanks", "Snake", "Pirates" and "Head Space".
I can't launch "Fighting Space" and "Rumble Cube".
So, the results are: my player supports all *.rkp were created for RK2608 (Tanks&Pirates)
and half from created for RK2606 (Snake&HeadSpace).
When I launch Snake/Headspace, screen is rotated, and buttons are weird.
