Ok, yesterdey I tried to install the new gui...and I got an error message, something like: you need libqt4-core (>= 4.7.0~git20100909-0maemo1+0m5)
So I tried to install libqt4 through apt-get, and after a few tries it began to download lots of things.
Finally I installed the gui, and now I can open it, configure my keys and play the games (but for now I think it is slowler than the previous version).
The thing is that now I can't play with mupen64plus :S I don't know why. I mean, I can open the emulator and chose a game...but when I press start, the emulator stops working and closes the window. The games just don't work.
I would prefer not to flash the phone -.- I have lots of things in it, but I like to play my N64 games too. Any help? I don't know what to do, I've already uninstalled the mupen64plus and downloaded it again...and same result.
Thanks
