NJ has released an update for the recently released build of MVSPSP, his NeoGeo MVS Emulator for the PSP. As the name of his update states, MVSPSP v2.3.0 now has a fix for King of Fighters 2003, allowing it to run properly on the emulator.

Here's the post from NJ, translated through Google Language Tools:

EBOOT.PBP3 species and source code difference. EBOOT.PBP only because of the following: 2.3.0 Each of the files to download, please use the override.

2.3.0 is compatible AdHoc and rendering software rendering in conjunction with the memory usage is increasing, thanks, but Experiment for private building, the per absolutely consider it. 2.2.4 these features are not just like me, so you use, or 2.3.0 AdHoc to disable, RELEASE flag to enable the compilation would slightly increase the available memory.

2.2.4 is generally safe for the creation of the 2.3.0 is like, for an experiment by adding code and the code itself is old. Using the API did not AdHoc and implementation of the samples to the public only in the update is performed. Remodeling and corrections are welcome, so please do continue.

In any event, here's the latest version of MVSPSP, along with the source codes. Enjoy!
