I used PSP Filer 2.5 to rip my own legit .iso of Mega Man Powered Up, but it doesn't work, and said as such on some list somewhere. Some OTHER compatibility list said it WOULD work with tweaking, but didn't say what. Anyone know how to get it to work with NOUMD mode, or where I should look? It's the last of my collection I need to get working on my memstick. I love batterylife + lower load times + not ever having to change UMDs.
