This may be a noob question so let me fill you in i got a psp for xmas and have been griping since seeing as i didnt know anything about cfw. well i finally bit the bullet over the weekend went out and bought an old phat battery from the local gamecrazy and attempted to make it pandora. after a couple poofs of smoke and praying that i didnt fry the battery i was sucessful. here is the questions i have the main question is i was searching around and do not want links or anything just maybe a list or something all the roms that i have tried with mame for all do not work they either dont appear in the list or if they do they do not work. are there only a certain few that work with mame 4 all? also as a secondary question i have been reading alot about time machine and would like to know how it works i understand the concept just dont understand as i am new to cfw does the cfw stay on the memory stick or does it actually load onto the psp itself and what is the deal with 3.90 m33-3 or higher for nand support dont know what that means or what it has to do with it. i want to help unbrick some friends and upload cfw right now i have desparter del cementerio v3. any help with my questions is appreciated

first question... mame4all doesnt work for me either... ive tried numerous times to no avail.

second question... time machine doesnt put the other cfw on your psp, they load onto the memory stick, so that they can be loaded from there.

third question... if you have a pandoras battery just use that with upms to unbrick it.

so what your saying is it loads it onto the memory card so if someone wanted cfw on there psp i should use cementerio not time machine. time machine is basically an emulator for cfw? or you run it off the memory card and if you want homebrew for a certain cfw you load it in that folder and it will run but as soon as you put your regular battery in it goes back to what ever cfw is loaded on your psp
