Ok, over the last few days, I have purchased two PSP’s. I have one that is still unopened. The other one came with firmware 2.71. I upgraded to 3.5 then successfully downgraded to 1.5. Then I read that you were able to play your PSX games on PSP. So I read dozens of threads here and on other websites and am still a little confused on the firmware needed to run PSX. I've found that you can use 3.03OE, 3.10OE and 3.40OE. Is there any others you can use? In my situation, I have the 1.5 firmware and the new one unopened (probably containing 2.71). The reason why I got two PSP’s is to be able to play my homebrew games on 1.5, and still take advantage of the new games the require an upgrade to the newer firmware. So the question now is..... is there a way to play PSX games on my 1.5 and still use it for homebrew games? or should I use the new unopened PSP. If I do use the new unopened PSP, is there a disadvantage in going to 3.03 to play PSX games? Keep in mind, I want to be able to do all of the following between the two PSP’s I own: • Play homebrew • Watch video converted to PSP compatible files • Play PSX games • Browse the net • Play the newest UMD games What do you experts suggest? I have detailed instructions on how to play PSX games on the PSP, so that part is taken care of, but I just need help with the firmware options…. Basically, just looking for all of the options I have. I really appreciate any help you can provide.
