Since SDLMAME for Ubuntu now has a repository I am no longer hosting the files locally.
The repository has the latest builds for Ubuntu v18.04 thru to v22.04.
You can add the repositories to your box in several ways. Here's a quick how-to, you can step through it or look for full details on adding PPA's on my Launchpad Page.
Open a terminal window (commands may be typed directly or pasted into it) and:
- Remove old sdlmame repositories (if any):sudo rm -f /etc/apt/sources.list.d/sdlmame4ubuntu.*
- Add the main repository for unofficial builds:sudo add-apt-repository ppa:c.falco/mame
- Now update the information on your box:sudo apt-get update
- Finally install the package from the repository:sudo apt-get install mame
The update manager will now take care of upgrading the package for you each time a new release is available! :)
