Ok why is there a problem with upgrading your PSP firmware? Doing something naughty?
If a game is not working because you have not enabled a feature on the PSP that this game needs or takes advantage of, then its a simple EULA issue - you take the game back to the store saying that you do not agree to the terms of the software and demand your money back.
Granted you opened a sealed game and the store will not take it back is probably true, I cannot see where the devhook software will make any difference to your scenario. You have to upgrade or you don't. Heck, at least it gives you the option to upgrade. Its not automatic.
The whole Tiff exploit issue I'm getting at allows you to play homebrew without changing anything. Consider it a hidden feature. Not a lot works with it, except that Ebook reader, I think Sony missed that out by accident - and maybe be in version 3.0 of the firmware....
In therory you could run the exploit and then remove it and take the PSP back if it developed a fault. Nobody would be the wiser. Changing the firmware voids your warranty and could brick it.
So I guess you are right when you say not to mention nintendo 64 emulators on the PSP. 
You obviously have zero idea on how DevHook works.
I have a firmware version 1.5 PSP. It is a SONY 1.5. I have not in any way, shape, or form altered the firmware on my PSP. I simply load DevHook, which enables me to play games that use a higher firmware on my 1.5.
I have not altered or flashed my firmware at all. My warranty is still in tact and I can return it whenever I wanted if I needed to.
And the TIFF exploit is a "hidden feature"
Give me a damn break. It's an exploit/hack/mod just like anything else. You can rationalize it all you want, but it's loading programs on your PSP just like DevHook does, and it doesn't alter a PSP any "less" compared to DevHook or similar.
As for why I don't upgrade my firmware... its because I don't want to. I've grown very attached to some of my homebrew and want to keep using it. A good chunk of it would work if I upgraded, but a good chunk WOULDN'T, and that's reason enough for me. Sony doesn't force us to update as you mention, so why should I?
As memory serves, you can run backed up ISOs on 1.5. The very reason that Sony noticed this flaw and filled it with a firmware upgrade. The kicker luckily is to lose that flaw with some improvements over Sony's firmware upgrade. Like being able to stream media to the PSP from your PC or to unlock downloading of PS1 games when they are available.
I cannot see where this devhook is of any value, other to prevent firmware upgrades, and give you full kernal access for using those said images. That's how I see it. Am I wrong?
Word of advice Lloyd: If you have nothing to contribute, we'll thank you to move on to some other area. Now STFU. You're making me want to stop coming here because of your evangelism.
I doubt you will stop coming to this board. If your hobby is arcade gaming, you will just ignore my comments like many of you do. I also think you should PM me and apologise for that comment. I know what STFU stands for.
You mis-understand devhook I think.
He seems to misunderstand a whole mess of things.
Yep you are right I do. I also misunderstand peoples actions when they try active engage in practices that are deemed questionable at best.
If in fact Devhook is simply a boot shell that allows the use of higher firmwares from within the 1.5 BIOS, then it is in fact likely not illegal. It is an emulator.
Again, you are making an excuse. You are not telling me anything.
I'm just against publicising software that "can" run backups of software which is being sold on the market right now. Something again which is not allowed to be posted here.
Sure, homebrew can enable piracy, but it doesn't mandate it. There are lot of neat homebrew games and applications for the PSP. I even considered developing some homebrew to enable me to use my PSP as a home-automation control system for my house. Would that be illegal?
while its true that devhook allows piracy, its also the only way to use homebrew, like emulators and still be able to play the games that require 3.0 firmware.
Bingo! Thank you. Some honesty at last. See? It doesn't hurt.
I love homebrew too. Being able to view PDF files now is a boon. I Use PDFs a lot in my studies, and my XDA is not the device of choice to view them on. I thought that way to go was the Tiff exploit to use this type of software, but its wrong and goes against what I'm saying here even if the exploit doesn't harm the indusrty like ripped ISOs do.
There is an unility called paperless printer. Its free (google it) and allows you to print PDFs out as Jpegs. Now I just view the Jpegs on the PSP. Clear type and I don't have to load as many pages into memory, something that PDFs have a tendancy to slow down the machine. So there is my solution towards non hacking protected software.
I don't see the point in playing MAME either, there are emulators on the open market like Namco Battle Museum, which seriously rocks. Check it out. I never thought Rolling Thunder could be as fun than on a bumpy bus.

Maybe Sony will listen to our pleas and allow homebrew to be run in a shell legally.
