PSP, all the way from 1.00 to 5.50 GEN D2 - DS Lite w/ M3DS Real (M3 Sakura v1.34)
PS3 3.01 - iPod Touch 2G 16GB Jailbroken - Xbox 360 60GB - PC, Q6600, 3GB DDR2, GTX260 (216) 896MB
ok once i tried the 3.40 OE a on my friends psp and it had trouble playin isos, homebrew and ps1 games im not sure why, this was awhile ago, maybe it was unstable then? it was about 4 months ago lol i got a psp 3.10 OE a and it works fine
3.52 M33-2 is the most stable in my opinion. it plays all ISO's and most PSX and PS1 eboots. the only thing that will set it off is if u try to customize the battery icon. but thats not even big enough to notice anyway. just dont put system_plugin_fg.rco on the system flash and itll be fine.
