Usa Psp 2.0 To 1.0.

Hi I Am A Newbie And Have Usa 2.0 And Just Downgraded To 1.0. I Did Not Think This Is Possible On Us Version But I Have Just Done It. I Got The Black Screen With White Letters But Only A Few On The Left Hand Side Of The Screen In The Middle Not Across The Top. When I Updated To 2.0 The Psp Got To 99% Then Got The Failed Message And To Contact Sony. However When I Powered Up Again And Checked The Version It Was 2.0 And The Umds Worked Fine. I Have Done This About 5 Times Now And It Works Every Time. Is This Normal And Right And Will I Be Able To Play The Gba And Snes Roms Etc Or Are These Only For 1.5. Any Comments Will Be A Great Help.

WTF? can you rephase that...i dont understand last part you have to downgrade all the time?

Wtf I Don't Understand Either At The Moment I Have To Downgrade Every Time Because I Have No Umd Emulator. I Cannot Believe I Have 1.0 I Am Still In Shock Can I Upgrade To 1.5 To Play All The Gba And Snes Games Or Will 1.0 Do This. I Know S**t About Psp I am Doing This For My Son I Do Not Even Have A Decent Memory Card Yet. I Have Just Been Messing Around On The Web. I Only Signed Up To This One Tonight To Try And Get Some Answers.

You didnt downgrade to 1.0

You just forgot to update to 1.5 after the overflow file tricks your PSP into 1.0. Next time search around for these things.
