Update: Dark_AleX discovered PSX problems in 5.00 M33 due to a bug in M33 code that is caused sometimes with certain icons. He stated, "I'm not gonna bother do an update only for this but I'll post the file that fixes this for anyone wanting to fix it manually replacing the file."
Dark_AleX has issued an update to the 4.01 M33-compatible plug-in, fixing numerous bugs along with adding support for UMD disc titles. Additionally, savestates can now be created on a per-game basis.
Keep in mind that PSPStates is compatible only with Slim units currently, due to increased memory usage.
* Fixed important bug in inter-thread code (semaphore wasn’t waiting due to interrupts disabled), that caused the load state to not be completely read in some cases.

Dark_AleX has released a new Custom Firmware Plug-In that allows users to save/load savestates of their current progress on PSP titles. Dubbed PSPStates, the plug-in is still in the experimental stage and currently is only compatible with Slim units, due to the increased memory usage.
It is advised to disable any other plug-ins while using PSPStates, as well as backup all data on your memory stick in case of data loss. Additionally, the plug-in is written specifically for 4.01 M33. Savestates created likely will not be interoperable with future Custom Firmware releases.
As a final note, it is highly stressed that you do not use the plug-in with a UMD inserted. Use of the ISO driver March33, which can be selected in the XMB by pressing Select, is recommended.
