Hi Pudding ! Thanks for this great port !!
May I share a couple of remarks ? BTW I mentioned some of them in the mame4all thread before, sorry for the duplicates.
1) I noticed that the sound of some NeoGeo games didn't work properly : for instance Pulstar.
2) Other little bug I noticed : if you only display the available games, if there are not enough games to fill the screen, and if you hit the "right" key, you won't be able to move in the list anymore until you've kit the left key.
3) I would absolutely LOVE if there was a way to get scanlines to work properly at the same time as the bilinear filtering (or if a PNG mask can be specified. It can improve the rendering a lot !)
4) I noticed that some games seem to have a bad picture ratio : for instance Strider should use more vertical space. (I checked on sdlmame on my PC)
Sorry for all those requests
Hope this helps ! & thanks again a lot.
