  4. What Firmware do you have?

  5. What Versions are there? And what do each of them mean?

  6. Downgrading http://www.psp-hacks.com/forums/about17935.html

  7. 2.71 firmware emulation • Download Devhook 0.44 and put everything on the memory stick. • http://dl.qj.net/index.php?pg=12&fid=8807 • 2. Download the 2.71 Firmware update. • http://dl.qj.net/Firmware-2.71-PSP/pg/12/fid/8046/catid/1633. • 3. Download PBP Unpacker: • http://www.pdc.me.uk/pbpunpacker.php?

  8. 4. Open the EBOOT.PBP with PBP Unpacker or similar and extract the DATA.PSAR file.

  9. 5. Put the DATA.PSAR in the root of the memory stick. 6. Run the included Devhook installer on the PSP (install flash0 and flash1). 7. Extract Devhook 0.44 again and overwrite everything in the dh folder (its going to be a couple of .txt which include the path for the prx's) 8. Get a decompressed 2.71 reboot.bin http://rapidshare.de/files/32183676/reboot.bin.html8. 9. Place reboot.bin in ms0:dh271reboot.bin

  10. Okay, now I have the PSP downgraded, what can I do with it? “Allows users to "view" the games memory and then edit essentially any part of a game through searching. You can find any code just by using search functions such as "Greater", "Less", "Equal", "Not Equal".” Which is similar to Artmoney, Tsearch or GameShark Pro http://pspupdates.qj.net/CheatMaster-0-6-Alpha-for-DevHook/pg/49/aid/69666
