    2. Configuration -> Use NO-UMD (Disable it)
    3. Go all the way back to main menu

    hi, I have a black slim PSP, and I want to know how to get my PS1 games to work on it without having to make a Pandora’s battery or anything like that. I’m not very good with tools. Can someone help me? I have tons of firmwares that I downloaded, and I’m not sure what to use on my slim version. Please help.

    August 23, 2008

    Well, you have to have custom firmware installed to play any of you ps1 games, or any game you download off the internet. The only way to put custom firmware on the slim psp is to use a pandora battery, now you can buy a battery and magic memory stick package for around 40 bucks, or you can find someone to install the custom firmware for you. Now i know its risky, but there are people on ebay that will install custom firmware for you for about 20 bucks. If you are willing to take that rout, i will do it for you for Free, send me an email if your interested . player_x_slayer420@yahoo.com

    Nope, Pandoras battery is the only way to go if you have a slim psp, especially with firmware above 3.50

    well, you dont have to make the pandora if you dont want to, you can buy a package with the pandora battery and magic memory stick online for about 40 bucks. usually that gives you a pandora battery and a 1gb memory stick with the needed software to install custom firmware.

    Hey guys, I have a little doubt…I have a PSP FAT…firmware 3.71 m33-4
    but some games, as “harvest moon innocent life” crash my PSP when I try to play…it just turns off Oo
    I wanna know what can I do…update the firmware maybe?
    and if I do so…can I still play my MS games without a pandora and without an UMD? thanks for complaining

    Most likely you need to update your firmware, I have the newest version of the 4.01 m33 and i havent found a game that wont work yet. and what do you mean by MS games? there are settings where you can make games play without having a umd in the psp.

    yeah, just visit dark alex’s web site to get the updated firmware, or if you have a wireless connection you can do the update on your psp. i have the 4.01 m33-2 and i have no problems running any iso, cso, or psx game.
