Just wondering why it is that with OFW you can download demos from the internet and transfer them to your MS and you can play the demo. If you transfer game over it won't play. ARe the demos signed and thats is what the PSP looks for and notices? If not can't we somhow convert any game to appear like a demo and it play the game on CFW?

Downloaded games are called ISOs. You need a CFW to play ISOs. So you need to get to 1.50 and then from there upgrade to any CFW you want. The best CFW is 3.71 M33. When you're on 3.71 M33, get the ptahc and install it to get 3.71 M33-3, the latest CFW and the best.

Demos are legal.

ISOs are illegal that's why you need CFW for ISOs.

yea your right aout the signature thing because in the playstation store they are selling a wipeout pure download that can work on any firmware. But if other ordinary people just dump their umd and put it up for download nothing special happened there. I guess with CFW it skips the whole look for signature process.

But his last sentence is wrong, you cant convert games to make the PSP think it's a demo. We told him how, problem solved.

DEMOs are .EBOOT files.

ISOs are .ISO files.

two different file types.

i THINK, if someone could find more about the two, they could make a .ISO to .EBOOT if they could make a converter. and the converter could add a counterfeit "signature" so the OFW psp would think it was downloaded off of PSN.

kind of like the PSX emulator. you have the KEYS.bin file, and that gives the psp certification to play the .EBOOT file.

i have a CFW PSP, but seriously, someone should look into this.

i beleive it would be possible. cause it plays demos, even after new ones are released. so the New demos gotta have some sort of line of code or something that tells the PSP, "go ahead and let them play the file."

so if someone could download the .EBOOT of WipeOut, and the .ISO version, maybe they could do something....

i dunno anything about that stuff, as you can tell, but its just using common sense! (it MUST be possible)

Yeah I understand that in order to play the ISO you have to have a custom firmware to play. But what is that custom firmware doing that the original does not. Is the original firmware looking for a signature before playing the game? And the custom does not? In that case you should be able to sign regular games and they should play with the original firmare also. I mentioned a converter. If there were a program created that would take a game and convert it to whatever format a demo is in then you should be able to play the full game and the console think its a demo. In the xbox scene there is a way to take all the security on the disk and copy that over to the disk and along with the image. If there was a way to rip the UMD Security code and all then it should play from the memory stick with original firware. But the answer to my question would be answered also by answering this question. "What does custom firmware do that origiaml does not" PLease no-one answer "lets you play copied games" I'm talking a more technical answer explaining the inner working of the firmware and what it adds or skips or whatever to allow you to play the ISO's and homebrew.

CFW is able to play homebrew, change themes, play ISOs/CSOs and so much more that the OFW can't do -that's not even a question; why are you asking and then you're asking not to give an answer. We shouldn't be detectives to your post, you have to be clear if you want clear help.

That's it, there's no more, no less to that.

Good lord. I know that custom firmware will let you play that stuff......I don't know how much more simple I can put it. You don't have to be a detective to understand the question....Let me see how to put it....How does custom firmware allow you to play ISO's and homebew and Original does not allow you to play it?

No need to get mad we're the ones helping!

On OFW Sony block copyrighted data. On OFW, Dark_AleX takes that option off.

I'm not getting mad at you. I'm getting frustrated that I cannot figure out how to word myself correctly. What kind of copywrite protection does the OFW have? What does the Origial firmware look for that the custom does not. Please don't say "Copywrite protection" because that is obvious. I guess I am looking for a more technical answer rather than generic "OFW don't play homebrew and custom firmware does and thats how it works"

Somehow I missed all of what you said. I agree totally. There must be a way of doing this. If its a case of the porgram being signed then it should not be that dificult to rip a game with the signature and play it from the memory stick. Yeah there is something in wipeout downloadable full game that is allowing to to play from the card. Would be awsome to be able to just convert the games rather than having to install custom firmware. There will still be reasons to install custom like the emulators and such..unless it can figured out a way to sign programs. People that make homebrew use PSP Software development kits right? shouldn't that program have some sort of funtion to add signatures? anyways, thank you for your response and sorry I did not see it earlier. I got a bit distracted.

oh it's no problem. lol

im just now checking the thread after posting that.

your right! they could learn to add the signature to homebrew as well, so OFW could run it.

i mean, youve heard of ChottoShot right? its a App for the USB camera. and its runnable on OFW. so homebrew should be able to get a signature too.

if someone could make a converter for both ISOs and Homebrew, i would totally upgrade back to Official. cause i cant run LocationFree player with 3.52m33-4. and i wanna try it out.

but at the same time, with sony seeing this, they could possibly make new firmwares that cant run the counterfeit signature. :(

but i know that it must be possible. cause think:

if you have the right combination of 1s and 0s or whatever it reads in, then you can make ANY program for PSP. (cause the revisions of Daedalus are just changes of the 1s and the 0s. even though you have to revise it MANUALLY. not just change code. thats impossible)

so with the right combinations, anything is possible for the OFW PSP!

but you cant just take 1s and 0s and do whatever. they must be in order and stuff.

kinda like a lottery ticket. if you can make that pencil bubble in the right COMBINATIONS of numbers, you would become a multi-millionare. but you dont KNOW what the numbers are. (so thats why people have to make stuff the hard way...manually with luck. only then can you attain the right numbers.)

i might not make sense, but i hope people know what i mean going with all this. lol
