In this version, the main differences with the previous are:
1.- CRT Filtering working: And it can be activated or desactivated.
2.- VICII chip is much better emulated: The sprites info is read per raster line. The sprites 0 to 2 info is read at the end of the previous raster line, while the sprites 4 to 7 info is read at the beginning of the current raster line. When either the info of the graphics or the sprites is read the mainCPU is stopped for a couple of cycles as per original VICII works.
3.- The cartridge games have been clasified in 4 folders: The ones working perflectly, and the rest hacing some kind of issue (control, video or unknown).
4.- The very detailed debug info can be activated or desactivated even only for the interruptions. This feature allows to trace how they work very carefully.
