Claus Windeler (GoodOldGames to those who frequent BeShare) sent me an-email about this. Here's what he said:

"BeEmulated is searching for a maintainer of MAME for BeOS. Over the last month and years Yoshi and Caz spend much time and work in keeping one of the greatest and most popular emulators alive on BeOS. Now it's time for someone else to step foward and complete the work. We don't need someone who "only" compiles the latest version, but adds new features, like a nice GUI, and tweaks overall performance. BeEmulated will help wherever it's possible. A free website, unreleased source code and all possible support is waiting for you!! If you are interested mail me."

So that's it. Anyone out there with the guts to step forward and volunteer? MAME is a great asset for BeOS, I for one enjoy playing games like Metal Slug in it, with thousands more to chose from. So write Claus and make yourself heard.
