I recently downgraded to 1.5 and I cannot put the PSP down since then. I was going to sell it before that but now I love it. I desparately would love to play FF7 on it and so I am very excited with the prospect of Sony putting out PS1 games for the PSP. However, I don't want to upgrade in order to do this. Does anyone know if we will be able to keep 1.5 and still play the PS1 games? Also, can somebody point me in the direction of the homebrew that allows you to play 2.71 and lower games and still keep 1.5?
