No, I believe you have the right to put the DVD in your computer, rip it to an .avi, and play it on your PSP even though your PSP doesn't have a DVD drive. Which is essentially what Dark is doing except with GBA games.
Except that there are legal ways of doing this. The PSP natively plays video files and a large number of DVDs and Blu-Rays come with Digital Copy features.
There's no legal, manufacturer-sanctioned way to rip a GBA game and the PSP doesn't play GBA games natively.
