OK, I've got 3.02OE-B and I got MGS PSX working perfectly on my PSP. I beat revolver ocelot, raven, the ninja, and now I'm stuck on psycho mantis. If you've played this on the original PS1 or PS2 then you have to switch control ports from player 1 to player 2 during the fight. ALL U OLD SCHOOL GAMERS KNOW WHAT I'M TALKING ABOUT. My question is>
Is it possible to switch control ports for a PSX game on the PSP?
What if theres a game like FF7, FF8, or Xenogears with multiple disk. How will the PSP manage PSX disk swaps?
Don't know where the fix is downloaded from but the fixed game is on the usual torrent sites. Its 486MB in size and should say its fixed in the description.
I found beating psycho mantis a problem aswell but I've got a solution!
When you are about to enter the room where psycho mantis is, meryl will be following you from behind. Stand by the door to the psycho mantis boss room with the card key just enough so the door opens. Then equip the nikita launcher and fire a rocket in the room, then aim at the statue on the left that has a psycho mantis mask on, this will blow it up. There is another statue on the right of the room so fire another rocket to destroy the other one. Then enter the room and start the fight and he wont be able to read your mind.
Even in the cut scene when you beat him, he will say
"So...you used the other...."
Just like he would if you switched the controller on the original PS1.
This method definatly works, as i've did it myself. I've just got to metal gear rex and have to do that PAL key malarky. :D
