The GP32 is a really cool predecessor to the GP2X and has been very successful on the homebrew scene. Although it looks like a Nintendo Game Boy Advance, it can do a whole lot more.

The GP32 was only really available in Korea at launch and it took months to get the GP32 into Europe (by which time the GP32 had evolved to the more feature-rich GP32 BLU). There was a lot of confusion surrounding the European launch and despite lots of very developer-friendly features; it was never really noticed by mainstream press / users. Additionally, the GP32 never made it officially to America.

The GP32 has a single processor compared to the dual-processors of the GP2X, both of which are faster than even the most overclocked GP32 by about 40Mhz. Additionally, the GP32 only had 8Mb of RAM at launch and the GP2X has 64Mb plus 64Mb NAND flash memory that can be used as storage. That's not all the storage you can use either. There's more of course but effectively the GP2X is a big leap forward from the GP32.

the moment, I don't know the answer to this question. You could overclock the GP32 somewhat, so perhaps you will be able to do the same with the GP2X. Still, the 200 MHz speeds are already faster than an overclocked GP32 by ~40 MHz.

The short answer is no, the long answer is probably not. I believe that Game Park hold the rights to the GP32 and anyway, the OS on the GP2X is just too different. Linux is a computer operating system and its kernel. It is one of the most prominent examples of free software and of open-source development: unlike proprietary operating systems such as Windows and Mac OS, all of its underlying source code is available to the public and anyone can freely use, modify, and redistribute it."
