well thats how it worked for me, did u try install it through app manager??
all u do is copy and paste the two files in the installation and java folder, then u go to app manager and find the game, open options and select install and now start the game from the main menu.

i only tried XIII from that list and it worked. Splinter Cell Extended Ops doesnt work for me

Ahh I saw in some other forum that 6600 can only run .sis files? Can someone confirm this and it'd be cool if you can tell me if there's any way to convert jar/jad to sis too.

Hey I downloaded a couple of games from the s60 thread(rayman3 & prince of persia). How do you get the games to run on a 6600 exactly. I've tried transfering the jad and jar files to the phone via drag and drop and installing them via nokia pc suite, but the games don't work eitherway. Do you need a 3rd party program to install games or sumthin? Any help is greatly appreciated, thanks .
