Comment 1 for bug 502191

This is the .diff file for the new upstream release - sdlmame 0.136.

To build the source package use

zcat sdlmame_0.136-0ubuntu1.diff.gz | patch -p0
cd sdlmame-0.136
chmod +x debian/rules
debian/rules get-orig-source
mv sdlmame_0.136.orig.tar.gz ../
cd ..
tar xvfz sdlmame_0.136.orig.tar.gz
and the source tree should be in
sdlmame-0.136

Compiled binaries are available on my PPA as well:
