I've decided to try one of the new beworld ports, namely ZeldaNSQ. It seems fun (and my children are very interested in it) but it has one big issue - the save dissapears every time you exit the game. As long as the game runs you can load it again, but the next time I start it I the slots remain empty. I don't think that's normal?
OK, now it works flawlessly. Thank you, beworld! By the way - is there any option to upscale the screen a bit? 640x480 is less than quarter of my monitor...
