I strongly disagree, theres alot of factors that come into place in the "real world" ... assembly programmers cost more money A wholy valid point I would consider beyond the scope of a "beginner" thread. I program in 6 languages (C, assembly, VHDL being amongs these) and about t...

Out of curiousity is the sony firmware written in C or assembly? or both? Ah, the language question. I'm guessing you might know this already, but since this is a newbie thread, let me ask "who cares"? Language choice is often a matter of preference. You see, the only instructions the CPU...

An interesting idea...

According to ye ol' wikipedia the PSP would need to send a RRQ (read request) packet to the TFTP server to get the firmware image. It also says TFTP runs on UDP port 69. Hm...

Re: (red herring)

Hmm, obvious answer: it is using the timestamp of the gamesave folder (\PSP\SAVEDATA\WHATEVER) Negative. Tried that. The date on the folder is the date of the first time I saved a game... about a month ago. Something else of interest I noticed. The save game manager says that the save data is 96KB,...

Yes, I have a MEMSTICK.IND also, but it is a zero length file.

Memory stick hidden data

I think I have found evidence that there is hidden data stored on the memory stick for saved games. Using the saved game mananger utility, I noted that the time stamp on one of my saved games was May 11, 4:35PM. I captured these files using my USB connection and saved them on my PC. I then went and ...

It's written in C, therefore you should use a C compiler.

Not quite sure what you mean by using C++. You mean using a C++ compiler? If so, the GNU C++ compiler (g++) will usually work.

Give more details. Are you getting compile errors or what?

AES exploit theory

The other day I got an idea for discovering the AES key used by the PSP for saving games. Basically the machine applies the function AES(DATA,KEY) = ENCRYPTED_DATA. Typically all we know is ENCRYPTED_DATA and it's pretty much useless to us. But what if we knew what DATA was in the first place? If we...
