I've been having problems with getting some ps1 games and some homebrew games working. recently i've been trying to get command and conquore working (either disk); it shows me a screen saying "slippery when wet" which i'm assuming this is who the game was presented by. But it never reaches the Playstation logo before i get an error saying "The game could not be started. (CA000005)" i have got this error before with other ps1 games (but only like 1 or 2 others) and several times with various home brew games/apps. I've been relatively successful with getting ps1 games to play on my psp. I am running 3.02 OE-B - do i need to upgrade? is this my problem? if so can some direct me with link to upgrade to the latest custom firmware? Another thing i wasn't so clear about is what game folder to put ps1 or homebrew games in (i.e. "Game", "Game150", "Game270"), besides the obvious explaination that is: the folders indicate what firmware version the game/software is intended for. Does it really matter? and how can you tell which folder to use?
