Yes overlay partially working now on my own ( have problem with scaling with multiple overlay but single scale fine, and also with input overlay that not input for now)
Iv'e had a quick mess around with the ScummVM Core you released a few pages back. The touch works well and seems to track the stylus really good, took my a while to figure out I had to hold the stylus to the screen to "click" but that's just me being me I did notice a few DSi Error's when loading a couple King's Quest games though
Wouldn't multiple overlays cause Emulation speed to suffer? compared to a single overlay?
