3 piece PSP Rom

Im unsure of how to get a 3 x piece PSP ISO to work.Do I need to connect them up before the game plays,if so,how?

What do you mean three pieces? Is it a split Archive? Just extract one and it will combine all the pieces into a single file.

Yes,thats what I meant Tirith.I didnt know the terminology for describing it.It was a 270mb file split into 95mb/95mb/80mb files as it was put on one of em free file sharing sites,which have a 100mb limit.I thought they had to be rejoined somehow,but its like you said,open up one and they combine.Thanks again Tirith,the bairn is playing Cars Race O Rama on his PSP now
