Ever since I got my PSP there have been a few things that I have wanted to fix. First, I updated the face with a liquid platinum face plate I bought from Lik-Sang. Then I ordered Street Fighter Alpha 3 Max from Capcom and got a bonus D-pad fix. Finally, I added an Naki Analog stick replacement.
Capcom's Dpad fix is pretty simple, it is justa piece of plastic that has double stick tap that you use to attach on top of the PSP's junk d-pad. Once installed there is a noticable improvement, and Darkstalkers is playable! Too bad I would have to upgrade to 2.55 frimware to play it! I will be staying with 1.5 for now. Thank you Sony!
