DAX has released version 2 of his PSPStates plug in for 4.01 M33 firmware. PSPStates is a savestates plug-in for the PSP Slim that allows users to save and load save states as they please.

This version has a lot of bug fixes and now supports UMD discs.

Changelog:

* 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. This caused black screen after state load (unless you just saved that state, in this case state was still in ram), or even worse, game not working properly due to partial load.

* Added states per game basis. The controls are slightly different: old controls now do a local
savestate/loadstate of the game, while pressing additionally select button will save/load
a global state. See instructions for more info.

* Fixed bug that caused normal sleep mode waking up inmediately.

* UMD discs and isos in normal UMD mode are now supported. However, they require to nullify UMD cache, by flashing one file. For details on this process, refer to the readme file.

DarK_Alex has released his savestate plug-in called PSPStates for PSP Slim units. This custom firmware plugin allows users to save and load savestates on PSP games. Its only meant for the PSP Slim as more RAM than the older fat model.

Some notes from DAX:

It is recommended that you backup the nand and important data of memory stick before using this plugin, in order to avoid posible loss of data.

VERY IMPORTANT: because of technical reasons, DO NOT USE this plugins with umd’s inserted,
and do not use it of course with UMD’s in normal mode, even isofs mode is not recommended.
Use only in march33 (recommended), np9660 or in homebrew.

Please read the read-me file for instructions and usage.
