well i wrote this on wololo first and i thought to post it here too:

I have seen a lot of ppl having truble getting this to work properly, therefore thought it wouldnt hurt with a quick guide/tutorial for this awsome plugin ...

First of all i just wanna say i dont take responsebility for anything that happends should your psp brick while using this plugin (i havent exprienced or heard of this ever tho) and i suggest you dont use savestates from other ppl or firmware versions ether, as i can not garantee what will happend when you load up af diffrent firmware into you memory than the one you got in the flash. (at least i think it sounds like a really bad idea to do and i dont think any good can come from doing that)

so in case of a firmware change, REMEMBER to delete your old savestates while your at it ...

first of all you will need the plugin:
5.00 : http://www.psp-hacks.com/download.php?id=1571
5.03 : http://www.psp-hacks.com/download.php?id=1769 + the above one
5.50 : http://www.psp-hacks.com/download.php?id=1771
6.xx : http://www.psp-hacks.com/download.php?id=2070

Now to install this correctlly you will need to first copy the plugin(s)to your seplugins folder, including or just make sure your seplugins folder have a folder named "SAVESTATE", this is important for this to work as the plugin itself do NOT create this folder and this is were it will save your states.

Now to activate the plugin(s) you will need to write a string or 2 in your GAME.TXT depending on your firmware:

ms0:/seplugins/pspstates.prx 1
ms0:/seplugins/states_patch.prx 1
ms0:/seplugins/pspstates.prx 1
6.xx :
ms0:/seplugins/states_patch.prx 1
ms0:/seplugins/pspstates.prx 1
and for 6.xx pspGO on internal :
ef0:/seplugins/states_patch.prx 1
ef0:/seplugins/pspstates.prx 1

I suggest to only use this on games you have backed up to your memory stick on "unhackables" becorse in order for this to work correctly with UMD games you will need to flash to file umdcache.prx to your flash0:/kd folder, and I STRONGLY RECOMMEND NOT TO FLASH ANYTHING TO ANY "UNHACKABLE" PSP!

and now for the activation controls, wich i guess can be a bit confusing, so i made a pic here wich will properbly explain this much better :

This means actuall 16 special save slots with this plugin, as GLOBAL and regular savestates are diffrent ... tho to change games with this you will need to do a GLOBAL savestate, just remember that when you load a regular state, you HAVE to be within the game you saved the state from ...

... and now i only need to say remember which buttons you use to save wich game states too, becorse loading a savestate from a game or state that isnt there (or regular state within the wrong game) will result in a nice psp crash

Big thanx to:
Dark_AleX for creating the plugin in the first place
Total_Noob for 5.03/5.50 patch
neur0n for the 6.xx patch
http://www.psp-hacks.com/ for having all the files ready to dowload

Happy state saving


ps. i will gladly answer any question if can answer

Edit: ... i forgot to metion that its NOT a good idea to have lots of other plugins active while using this plugin (is it ever?) as it will proberbly crash, i use it with tempAR and sometimes mp3plugin_lite too, that useually works for me
