OK, I will provide a tar.bz2 next time. Any convention on the naming of this file?
That's great. If you pm an email address I'll give you permissions to edit the google drive folders directly (never tried, I guess it's possible).
As for the naming convention, the actual binary needs to be "groovymame" regardless of the bits, so GA can handle it. The compressed file is labelled like this:
For default Linux builds:
groovymame64_162.015g_linux.tar.bz2
For XInput enabled builds, which is required for lightguns:
groovymame64_0160.015g_wiimote_linux.tar.bz2
Ves was providing the later ones although last one he built was 0.160. I don't know how many people out there are really using lightguns but I believe the default NO_XInput build is safer for compatibility according to the comments in the makefile. Anyway the mouse support is broken in current GM with whatever option and I don't have the time/energy to investigate the issue right now.
