None the less,
alochol 120% is the best one out there. Converts lots of your games to almost anything (including .iso, .bin, and even .msd, plus lots more!)
It will check whether its a playstation cd or playstation 2 cd (or more) dump it, give you you're file, and you are good to go.
If you want to play playstation 1 on your PSP, tell me your firmware (must atleast be 1.00-2.80 firmware). If it is, then you will have the choice:
Of Upgrading from a 2.71 SE-A/B/C custom firmware
or
Of Upgrading from a 1.50 firmware. (1.50 reccomended)
So get to 1.50 (reccomended) and download the
3.02 OE-A auto installer! Once you are
at OE-A, update to OE-B by using
this updater.
After you are at OE-B, update to 3.03 OE-A using
this updater.
After that, PM me for the files to get playstation going on your PSP Firmware 3.03 OE-A!
For all the files located above, please read the readme on how to install, if you are un-clear about anything, post here.
