Half-Boiled Save Game Data Exploit Found.

Save games exploits are popping up everywhere as of late. The PSP scene makes it strike 3 for save game exploits, as Japanese coder mamosuke found a new exploit. He’s calling it the “Half-Boiled” exploit. This save game exploit is from an unknown Japanese region game and has been tested on a PSP-2000 running 6.20 OFW.

Why Mamosuke is calling this a half-boiled exploit as he can only change (Value1) and (Value2).Maybe something useful could come of this, perhaps someone in the know could get in touch with Mamosuke and see if this game exploit be worked into something of use?

Some notes from Mamosuke

I found a PSP savedata exploit in a certain game(region:Japan) which could be able to put any data you want in some registers including $ra. It is available in OFW6.20.(I tried with PSP-2000)
Now I call it “Half-Boiled” SAVEDATA Exploit.
Some of the registers can be changed to any value,but only half of them.
$raを 0×00(Value1)00(Value2)
For example, $ra to 0×00(Value1)00(Value2)
It means that I can change (Value1) and (Value2) only.
Ya,half of .So this is “Half boiled” exploit.
I can’t confirm where a balue “00″ come from.
(“Value1″ and “Velue2″ are confirmed.)
I tried to change all of the data “00″ in SAVEDATA to “61″ or “41″, and found crashing as before, but the value of registers did have no change: The situation remained unchanged.This would be distinctive of this game.
I have not investigated all of them so that I don’t know this is useful as an exploit.What do you think?
