@mitu OH sorry it's the default Gnome

@mitu I'm not sure how to describe it. I've tried 3 different versions of Ubuntu and Pop OS and they all do the same thing after installing RetroPie. It will crash once when starting for the first time then work fine. The 8bitdo buttons don't program correctly the first time but will all map the second time. Then after I run a rom it stops recognizing the 8bitdo or it won't even load the rom and just locks up the system. The bluetooth stops responding on the OS desktop as well. I'll try to look into the 8bitdo firmware and see if that is an issue. I'm at a loss at this point.

@wolfyn-claw I have had similar problems experimenting with Ubuntu 64bit. I don’t believe your going to get much help with that. However you could try installing retropie on raspberry pi is beta 64 version. It worked for me.

Ubuntu 18.04 has 5 years of long term support (LTS, i.e. updates) for many of its software packages, whereas 18.10 only has 9 months. See https://www.ubuntu.com/about/release-cycle for more information. The number behind an LTS' version (e.g. 18.04.1) indicates the "point release" or "snapshot", a downloadable installation image which includes any previous updates. An installed Ubuntu LTS becomes the point release via the regular updates.

This may be negligible for a completely local RetroPie. But as soon as it's connected to a network and thus, prone to remote attacks, its system should be updated regularly, and an LTS strongly recommended.

ok. built fine here on my Ubuntu 18.04.

Thanks.

I just found out on the emulators forum which is in Russian that as of April 2017 the author had no plans to incorporated command-line launching of game image (iso) files. This means you can only launch 3DO games with Pheonix v2.8 via the GUI unless he decides to update the emulator to support it. He said it was a lot of work in his post. Its too bad because the emulator is the best one for 3do.

lr-4do has lots of bugs and many games are not worth playing IMO.
