Japanese coding powerhouse NJ has just released the newest version of his CPS2 test Emulator for the PSP, updating it to version 5. If you would recall, NJ has sent word a few days ago that version 5 is in the works. Well, now it's here and it's ready for you to download.

We've been told that the cache files (system) that had to be written prior to running the games had to be overhauled. As such, those who will download the the CPS2 Test (and that's most of our PSPUpdates readers) would have to make a new cache file for their game, otherwise the games will load up an error.

Also, the sprite management and processing were re-written anew to improve speed and stability with shooting and side scroll action. Sprite drawing and processing were substantially modified. NJ managed to correct the problems encountered with sprite masking process. He used a method that does not decrease the speed of the system.

NJ has posted some screenshots that show the problems he encountered when running several games (CS Club, Super Street Fighter II: Tournament, Dimahoo, Giga Wing, Progear, Dungeons & Dragons, and Shadow Over Mystara). If you encounter problems, just let NJ know through the comments section.
