Frankly speaking, just like some guys had pointed out before, that one of the biggest limitation on psp is that it has no mmu, thus userland programs would not be able to take advantage of features like share libraries which could have significantly reduced memory consumption at runtime. This is not...

Sorry for long delay guys, life has been kind of driving me nuts lately. I have uploaded the files to another file hosting server again. For those who still need the packages, you may have another try.

I was wondering if it is possible to get ADOM http://www.adom.de/ to run? I get some error about bad header magic, is it because of the file system? Any suggestions? The "Bad header magic" has nothing to do with the filesystem. The linux-binary on adom.de is an ELF-binary but the PSP need...

Has anyone had success using ncurses? I tried to cross compile ncurses 5.6 and ended up with ncurses.h missing function prototypes and I'm getting undefined references to initscr etc. Believe it or not, I did try that before when I tried to port the text mode mouse daemon, but encountered so many c...

I think it is possible. Recompile the kernel with the ISO fs support, and place your ISO files in MS, then just mount the file using the loop device.

I think I can answer this. Currently bmp2c can only handle 24-bit bitmaps (24 bits per pixel), and the bmp file that came with the original osk package is just one of those. If you wanna use your own images, you probably need to use one of those format converters to turn your files into 24-bit forma...

Perhaps let me put it this way. It is hard (for me) because the hardware specification (or the programming interface at h/w level) of that psp wifi device is still kept in secret by Sony.

Hi all. I have released a new version of uClinux which hasn't been tested on slim yet. Would somebody help to test it, to see whether it can successfully detect the extra 32M RAM on slim? It can be downloaded from the following link:

Well, theoretically speaking this is still possible but just highly impractical. You can still "map" part of the memory stick into an address space outside the physical RAM. As a result, any attempt to access that range will immediately trigger a bus error which could be caught by a specia...

You mean you are still getting the same compilation problem? or keep getting your psp shutdown during kernel booting? If it is the latter, did you try to boot it under the 1.5 firmware?
