3) Install psardump02a in PSP/GAME (with kxploit for 1.50)

- For 1.00 firmware : copy MPHFL (in 1.00 folder) to PSP/GAME folder of your memory stick
- For 1.50 firmware : copy MPHFL and MPHFL% (in 1.50 folder) to PSP/GAME of your memory stick

so it runs on 1.5 and 1.00

- Load 1.00, 1.50, 1.51, 1.52, 2.00, 2.01, 2.50 firmware

it loads all other fw on 1.5 and 1.00, so you could have 2.5 fw running on 1.5, which is still really good

Yea that is good. That means u can play 2.5 games on 1.5 i hope

man i think im either stupid or did something wrong, but i don't think that it runs on 2.5...i put data.psar in root and put the firmware launcher in GAME folder, it's homebrew so it doesn't run on it.

EDIT: (with kxploit for 1.50) my fault sry lol

o nvm...i didn't read it right. lol sry

so it means that i can't use this with my fw 2.5
and make it 1.5

cannt download please help

THIS IS NOT A DOWNGRADER!!!! It is a homebrew app (which 2.01 and 2.5 are not capable of yet) that can load other firmware versions off the memory stick.

where do you find the program psardump02a?

It's not a downgrader but it could be possible to play 2.5 games on 1.5 using this eh
