firstly forget about try/catch handling, its more basic error handling....
yes the above statement is pretty close to the truth, the save game exploit DOES inject its own code if i remember correctly, havn't they made a hello world app for that exploit? and the tiff exploit is chickhen again.
the error handling has FAILED, and the psp waiting for input.... the psp error handling isnt that good really, but if it detects something it'll reboot/shutdown ur psp... but when it doesnt, the cfw is not running fully or has crashed, or is in error mode whatever, it allows you to bypass the security checks...
I think you understand better than you think my friend, exploits as you may know will differ depending on what type they are, for example the tiff files are not pictures there images of data in chickhen, but with the savegame exploit, u need an altered savegame. both of these will get the cfw to run the part of its own code that causes a crash or malfunction, allowing them to then load the files. but with the savedata one, the user has to do it from the xmb, instead of letting chickhen do all the work....
I'm sorry but i cannot give you too much information beyond this point, like i was saying b4, i dnt consider myself a hacker, nor a wannabe hacker

(even worst!) but if u keep asking questions I'll answer as far as I can, but really GOOGLE IS YOUR FRIEND!

Thanks for the info.. i'm really looking forward to know more about this.. i'd like to share and hopefully influence the concept of teaching a lot of potential developers how stuff came to be ( like chickHen, now i know thanks ).. i mean in a really, really in-depth manner. and in result it'll increase the chances of someone creating something useful and something better for our community Thanks ( not sure how to give an equivalent karma anymore LOL )

well if u wanna do that get on a forum that has developers, or at least active ones, I think I'm one of the few on the forum that can code 4 psp (mods/admins excluded) I wont name names of forums, and dnt leave here. this is because other forums arn't always open with people they dnt know, and can be blunt and insensitive. not a major problem, but thats the main reason i stay here.... o and thanks is our reputation, see at the end of each post u wanna thank me for...
@xionzz I will not help u unless u ask properly - more info needed and do not hijack a thread, i was enjoying talking about exploits, its not a normal thread topic XD
