(adsbygoogle = window.adsbygoogle || []).push({}); Most of my mod menus are GSCs and I have no idea how to inject them
and also is it required to use eboots that come with mod menus?

Use GSC Studio in order to inject the GSCs man It comes with a tutorial I believe, but for the most part it's pretty self-explanatory.

Is GSC studio for pc or ps3?

Try following this it should narrow things down for you.

Thanks, that really did narrow it down...

Enjoy. :p

Ugh, I really want to downgrade my PS3 so I can do this.. Just for fun of course

You cannot perform modifications to the system or any game without having a downgraded console.

Yeah i got that much Nat, I just did the Min downgrade checker on my Ps3 Slim Cech-2501a and it said it's down grade-able to 3.40. I'm looking at E3 Flasher vids now. My question was, do i NEED that flasher for the slim since it is down grade-able to 3.40? or is it because it's able to go down low as 3.40 tells me that i CAN use the E3 Flasher??????
EVery drip of knowledge you guys can give me I would appreciate it.

I wanted to go the CFW with the Spoof to play online and maybe learn how to use custom menus for fun.
I'm learning as I go and I am catching on quickly thanks to everyone's help here.

If you want you can add me on ps3 and I can use a mod menu which I can share so you can use it, without a jailbroken ps3.
