im not really sure what im supposed to put in the iso folder (i know an iso but i dont really know what that is) i extracted everything off my lumines umd but what do i do with it?

I guess it would be mean to laugh at you. So I'll explain it and then maybe you can laugh about it.

Technically an ISO is the raw make up of a disc. Usually created by having a program dump it into a ISO. The files you have from Lumines doesn't work with this type of loader. So what you should do is find a dumper and dump your own UMD games, you will end up with a ISO file that you can put inside the folder and then just run the program.

i tried a dumper program but the only one i found was for 1.0 but have 1.5. are there any that work for 1.5?
