PSP

[aw3se4dr5]

I just had a thought that RockBox could be ported to PSP.   I got the idea when I saw my brother looking up 'psp homebrew hacks'.  So he found a few, and they were all in binary format.  Then i did some research(which took 2 min.  ) and found out that PSP has a MIPS processor.

So, Anyway, could we possibly program (or tweak) one of the existing bootloaders (for screen size, hardware i/o codes, etc...) and change some "makefile" or "sources" file so that GCC compiles for a MIPS target.

Then of course, we would take the binary, put it on PSP, and test it with a homebrew hack (however they work )

would this work or am i oblivious to some obvious fact that would make this impossible?

GCC can do MIPS, but you'll need to write drivers and a bootloader for the PSP, just like any new port.

Yes, were Rockbox to replace it as a default firmware games and UMDs would be completely out.

In theory, for those who have homebrew-capable firmware (or using the TIFF exploit, depending on what is accessible through that, and whether Rockbox can function without the kernel-mode on a PSP) it might be possible to adapt Rockbox to a stand-alone binary for use as an audio player.

Loading the binary isn't really a big problem since PSP homebrew already has a variety of methods for loading one, so the bootloader step can mostly be skipped. Some SDKs have been created for the PSP as well, so really you have a starting point for a port right there, since there's a good deal of hardware information among that I'm sure. In all honesty though, it'd be much more like running a simulator on the device, since Rockbox *is* structured as an actual firmware.

I wanted to have rockbox on my psp for 2 main reasons the sound doesnt get loud enough and i want my music more organized...here are my idea's for it...

Its needs to be an eboot file, not a complete replacement.
the eboot file can be just a bootstrap.
it can refer back to the .rockbox folder like any other firmware replacement for an MP3 player so it can be easily updatable if the source rockbox code is used...
a .prx file can be made for Custom firmware 3.71 M3-3 and any higher M3 CFW for autoboot in its recovery menu.
The PSP has two 32-bit MIPS32 R4k-based CPU that runs at 333mhz
The rest of the information can be found here... http://en.wikipedia.org/wiki/PlayStation_Portable

There are many engines that can run on the PSP which include:
LUA
C and C++
Python (Stackless)
Java
Basic
many more...

I'm know that a SDK for each is out there for free...although I dont if any of this will help...
