I have been trying to convert Wing Over 1 to play on my PSP which actually works but the problem is that the ingame menus have no letters. Sadly Wing Over 1 exists only as either Japanese or European. I have tried the PAL version that is found in the forums in here and also tried another image from another site. I have 6.20 PRO-B10 on my psp and I tried with either the default popsloader or by adding 3.71, 3.72, 4.01 and 6.60. for 3.71, 3.72 and 4.01 I got an error while on 6.60 I saw no difference.
