Since NJ has just released an update for his EMUs for the PSP Slim, but without adhoc support, AhMan made some little changes and compiled them to support adhoc. Also, the original 2.2.1 versions from NJ will only work on PSP Slim. The ones here also support the PSP Phat versions because you can only play adhoc with the same version.
