I have MinPSPW + DevC++. I've tried to compile Flash Led sample.
I've got an error:

but it creates pspboot.bin anyway. So I can just ignore this error?
Yes, you can ignore it.

[How To] Make Booster's IPL SDK work with GCC > 4.0.2

Hi. Today i was experimenting with Booster's IPL SDK and my IPL wasn't working, even if it compiled correctly. Searching in this forum i found that the IPL SDK doesn't work with a GCC version highter than 4.0.2. I found a solution to this problem, so i wrote this short How To. The solution is deleti...

You can't get the size of a malloc'd memory region with standard libc functions. But you can take a look at the mallocr.c for the newlib: http://sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/src/newlib/libc/stdlib/mallocr.c?rev=1.17&content-type=text/plain&cvsroot=src You can see this: chunk-...

I've got some info. In PSP GO! you can check for updates in the MS. The PSP will say the updater version and run it, if you want. When doing this with the AR on the MS, it says there's an update to 9.99 and, if you run it, it runs the AR. Some years ago (tested on 2.50) taking 1.50 update and changi...

Re: Strange Entry Point in Datel's Action Replay

I think they used an exploit. Look at the Entry Point - it's 0x000000AC!!! What do you think about it? That's probably an offset from the module base. Remember, it's relocatable. Oh. Yeah. You're right. I'm so sorry :S Well, there's another thing. Can someone explain why the number of segments is 1...

The eLoader isn't complex. It just load the ELF in memory (along with all the sections), resolve imports and jump to start address of ELF. The really PSP-dependent part is resolving the imports.

parts 2 and 3 aren't decrypted by psardumper... otherwise is would be too simple :P

take a look at this: http://forums.ps2dev.org/viewtopic.php?p=84468#84468

you need to take decrypted part1, reverse it, decrypt part2 & 3, decompress them and find the keys.
