The main security of the PSP is in the "Kirk chip". Currently there is no public knowledge of the exact algorithm & keys used. The "main" & "payload" part of the IPL is not directly protected by AES. Your question seems to suggest you are questioning about the p...

My wild guess would be some problem with OPENSSLDIR

"usr" "local" "pspdev" "psp" "ssl"

looks like the path to your openssl. It is probably not being "quoted" properly.

Some quick test indicate that 0x700000A1 was introduced with 3.70
sysmem.prx & loadcore.prx upto 6.20 seems to be using the old reloc type (possibly because it is handled by IPL so the reloc type hasn't changed)
All the order files with 0x700000A1 reloc table format use the new reloc type.

names in C++ are mangled.
Usually

A quick look review end of text section is calculated from imports, it will have problem with any file with no imports like sysmem.prx.

"ModuleInfo" is probably a good point to split code and data.

Problem with prxtool release 245x

Any person using prxtool release 2457/2458/2459, the version with updated reloc format? I don't known if an issue with MinGW or prxtool, when I tried to dump files from 3.71 and above (e.g. the simple clockgen.prx), prxtool have (slightly) random crash which seems to be releated to memory. This file...

If you want to understand the Makefile, read the doc/spec on the Makefile :) The basics I know is that the format is like this: target: source files required to build this target command to execute That "%" will looks like a template, i.e. to build "a.prx" requires "...

file is of type char*, sizeof(file) equals to sizeof(char*). The result is always 4 in this case. I don't know if you can get the size of the memory allocated from the pointer.

It seems LED flashing is not working properly with PSP-2XXX. At least I found when writing stuff to MS with PSP-1XXX, MS led will flash. Writing stuff to MS with PSP-2XXX, it will work but MS led will not flash. PSP_IPL_SDK_05 only work with gcc version 4.0.2 (or maybe lower, but not anything higher).
