Also, don't forget that the Vita can also use moving blocks of data, which necessitates the B200 codes, on top of pointers.
So until someone figures out how that works, all pointer codes are a crapshoot, and the vast majority of the time, will lead to some kind of crash at some point, no matter how good someone might be at finding pointers on another device.
Until someone restarts the research on properly hacking cheat codes specifically for how the Vita allocates memory, anything that is not a static code is pretty much false hope.
And before anyone chimes in to argue, if your solution is to restart and the code will work again, it means that the code doesn't work. It just works a certain amount of the time. The only time a working code will crash your game is if there is a built-in sanity-check (like Dragon's Crown) or you exceed a game's allowed value for something (as in, making your infinite money code for 999999, when the game maxes out at 9999).
Obvious exceptions being codes for effects in a game that may conflict with the way the game engine works, in some way.
The only codes as of right now that are solid are the A### codes, since they modify the actual programming of the game, rather than random values. And those are only solid on the exact version of the game they were created for. Want those codes for Binding of Isaac 1.1 [USA] [NoNPDRM], but you have the EUR version at 1.22? Good luck. Vitacheat won't even let you anywhere where those codes are to find the values and port them over. You have to decrypt the EBOOT and decompile it. Then you have to know what what I just said means, and you have to know what the decompiler is telling you, what you're looking for, and what to do with it. I'm one of the folks who figured out what we DO know how to do with Vitacheat, and I don't know anything about the things I just said.
I mean, keep it up. By all means. Maybe one of you will figure it out. But for those of you who are frustrated with it, it is what it is. The folks who can do stuff can only do so much, and the folks who know how to do more don't give a sh*t.
On top of that, the firmware you're on can have an impact on how codes work, whether you have to use a different version of Vitacheat, just so many things, so almost every non-static, and I might even go so far as to even non-B200 static codes, are just really good, at best.
We can't even search for 64-bit values, which game devs LOVE to use on Vita games. If you have a pointer with a 64-value, how are you going to find it, let alone make a code for it? Don't have the option for 64-bit values in Vitacheat. We have to chop them in half and use two codes.
My point is, don't beat yourself up or bash your head against the wall because you're having a hard time making codes. Making cheats for the Vita is a sh*t show for everyone. It's not just you.
