What firmwares do you use atm? I have 3.52 M33-2, and Castlevania doesn't work for me (after launch just black screen). I think it's because Castlevania requires higher FW than 3.52, but I've heard that 3.71 (the newest) has problems on fat PSP. Does it work on perhaps 3.52 M33-4 or 3.60?
EDIT. Got it working, just had to change the ISO mode from m33 driver to sony np9660 driver.
Yeah, I'm on 3.52 M33-4 and I have to do this with a lot of games.
Also, this game (or this series, actually. Maybe even this GENRE) isn't for me, man. Castlevania, Megaman, they're all games I really tried to like at some point in time, but it just did not go over well. They're hard and I'm not especially good at them to begin with, and it all just comes together into one unfun experience. I really wanted to like this! Question, though. Is SotN any better/less difficult than this? The port of Rondo of Blood felt slow and difficult, and if its sequel is basically the same, then I won't bother. I think I liked older ones better, if only because it took way more hits to kill you. I can do 3D action games, but once it starts going back to the 2D action ones, I just immediately start sucking at them and having zero fun. I sort of feel like I'm missing out, but oh well!
