As all may have known, since E3, Sony has been releasing PSX classics that you can download to your PS3 and then copy to your PSP. And I have got to say, THANK YOU THANK YOU THANK YOU!! I've been waiting for the metal gear solid game and Original (well any resident Evil)for PSP for a very long time. I am enjoying playing these games so far and are a great buy. Metal Gear has some control difficulties, but is still worth having. Meanwhile Resident Evil has perfect controls for the PSP beacause it does not require the anolog stick or L2 R2 buttons. I have so far beaten Resident Evil with Chris Redfield. I'm playing as Jill currently. I have not beaten MGS yet, but it is very fun so far.
Switching weapons in MGSis very difficult due to the fact that the PSP has no L2 or R2. So to switch weapons you must use the anolog stick. In MGS I'm stuck on the boss Psycho Mantis.
I wish there were more PSX classics on the PSN like Resident Evil 2,Tetris, Marvel VS Capcom, I honestly did like Jersey Devil, I'm not sure if its there but last but not least,Tomb Raider.
What I would really like to see though now are PS2 games for PSP(Mostly Resident Evil). Like Resident Evil 4,Resident Evil Outbreak, Resident Evil Code Veronica, Metal Gear Solid 2: Substance, Metal Gear Solid: Sons of Liberty, Metal Gear Solid 3, Rogue Trooper, Devil May Cry (the series), Kingdom Hearts 1, and a few more.I do hope very soon(and I know because of our technology we can) is to make PS2 also available for PSP. I woudln't mind having to downgrade the graphics, becuase to have some of these titles, it is well worth it.
