Hi man, thanks for your help...basically its the same as the older release.
Just change the background, instead of beeing separete full images its now a 1px PNG. The other functionalities are the same.
The 4x3 theme is the same, just make new images to the video frame and title info, and also change some percentages on the games wheel height.
Im trying to figure out how to mane it fit well on just 1 theme for both res but dont have to much time to investigate, thats why i create a new one, just to use it till i could fix the other one.
Also has some pending features, like adapt the second theme that the original designer did, try to add a nicer systems menu with pictures and some info of each one, and also add some game descrption feature. But i dont want to make it more heavier to, now it consumes about 100mb of ram for a gamelist of 80 roms.
