Run Time Error T.T

I wonder, why are you such a useless trash, I mean instead of actually solving the problem you keep pretending that your emul doesn't have this type of problem by repeating this "you haven't installed firmware, read the quickguide blahlbah" ?

I have my log saying

S Successfully installed PS3 firmware.
F LDR: class std::runtime_error thrown: Failed to load /dev_flash/sys/external/libat3multidec.sprx: Invalid stream or file not found

What, are you still going to pretend that the problem is "you haven't installed firmware" ?

I approved your post but you're still getting banned for it.

There's nothing that needs to be fixed besides your anger and manners.
Installing old firmware versions won't work.
You need to install the latest version which can be downloaded from the clickable PlayStation.com link found in the Quickstart guide.
Older versions don't have libat3multidec.
