[Playable] Ridge Racer 2 DEMO

[solarmystic]

Rashiraj, the demo that you modified for CFW 2.71 works perfectly on the latest revision 0.7.6-627-windows, but the unmodified one doesn't work, and produces the "Failed to load executable:Missing Key" error instead.

How did you modify it to work for CFW? Perhaps we can do it for other game demos to get them to work for the emulator.

Okay firstly you'll need a modded psp and also a windows pc.

Instructions : With some pbp utility, such as pbp unpacker, extract the files from the Ridge Racer 2 demo pbp. Put the extracted file DATA.PSP in the root of memory stick.
Run the decrypter test with 1.50 kernel (GAME150 folder) if you are in 2.71 SE-A or in devhook emulating 1.50 if you are in HEN.
The decrypter test will output a file called "DATA_OUT.PSP" in the root of memory stick. Using this file as the DATA.PSP, rebuild the pbp. Change the text in the SFO "2.81" with some hexadecimal editor to something <= 2.71.
You're done. Please note that this only works for ridge racer 2 demo and nothing else but feel free to try it on other demos.(Exploit by Dark_AleX)
Also i can't find the pbp unpacker tool which i had downloaded years back in my laptop now so you have to google for that. Sorry.
