I know that this thread is a year old, but as it seems to be the official thread I'm asking here:
First, there was a 1.3.4 update (the 6.xx plugin thread has it, as well as the official developer's page).
Second, I'm trying to make this work with pspstates under 6.60Me 2.2, but so far I had no luck either with pspstates_kai.prx (I think the one from neuron doesn't work under 6.60 fw) and pspstates_kai_mod_umdid.prx (renamed) from pspstatesmenupict MOD (which works fine uneder 6.60ME 2.2). Has someone managed to make this work under 6.60?
Also, I don't know if I'm supposed to add "ms0:/seplugins/pspstates_kai.prx 1" to game.txt or the only requirement is to have pspstates_kai.prx in the seplugins folder (I tried both, neither worked).
Finally, if ABCanG is still here, I'd like to request (if I can make pspstates work under 6.60) a change cpu/bus speed feature (maybe by pressing start to toogle speeds or L/R, just the usual 166/83, 222/111, 333/166...). It's the only thing I'm missing from this plugin.
I really like the plugin, but all its features can be obtained in 6.60Me 2.2 trough combining "game vhs menu" + pspstatesmenupict MOD, but I think a single plugin handling it all is better than two (and I realy like having a custom image as home screen and the pause game feature when pressing the home button (game vhs menu has this feature, but it isn't as quick).
Anyway, great plugin, too bad I didn't discover it until now.
EDIT:
I realized that the problem was that customhome/pspstates doesn't create the folder ms0:/seplugins/SAVESTATE by itself and can't save anything if the folder isn't present. 1.3.3 works fine even with pspstates_kai_mod_umid.prx modification by LMAN which has some improvements.
EDIT2: I made a couple modifications to 1.3.4, it is more stable now for pspstates/game pause function:
