so i'm looking at this url that the psp checks to see if it needs to update itself..
http://fj01.psp.update.playstation.org/update/jp/psp-updatelist.txt which contains
| Code: | # JP
Dest=00;ImageVersion=00000178;CDN=http://dj01.psp.update.playstation.org/update/jp/2005_0324_e32eb27980ba8b291eb803e3397e4b24/EBOOT.PBP;CDN_Timeout=30; |
and i'm looking at the similar file at
http://fj01.psp.update.playstation.org/update/us/psp-updatelist.txt which has
| Code: | #JP
Dest=00;ImageVersion=00000000;CDN=http://dj01.psp.update.playstation.org/update/nodata;CDN_Timeout=30;
#US
Dest=01;ImageVersion=00000000;CDN=http://du01.psp.update.playstation.org/update/nodata;CDN_Timeout=30;
#EU
Dest=02;ImageVersion=00000000;CDN=http://de01.psp.update.playstation.org/update/nodata;CDN_Timeout=30;

and i'm wondering... if you do a DNS redirect like was done for the browser... and host a fake "psp-updatelist.txt" on your server, and change the contents of the text file so that the psp fails the update check and tries to update. could you replace the url for the update with a different url and have it copy whatever was at that url to the memory stick? whats more is could you have it copy a file from the umd?
i'm guessing it would look something like
| Code: | #US
Dest=01;ImageVersion=00000000;CDN=file://disc0:/PSP_GAME/famename.here;CDN_Timeout=30; |
could be an easy way to pluck files off the UMDs... lol as long as you know the structure/filename

| well if you got it to download a custom update file from the url you've given it, then when it's run from the memory stick it would still check the firmware version and wouldnt run the update. If thats what you're talking about |

| He's talking about forcing the network update function to copy a file from the UMD to the memorystick by spoofing the psp-updatelist.txt. |

| It would be easiest to first test this by trying to copy data off the memory stick to itself. |

| This doesn't work. You can spoof it to download from http:// URI's but not file://. |
