Well folks, in the process of compiling and then building debs (amd64) for these 3 apps advmame, advscan, and advmenu (http://advancemame.sourceforge.net/)).
For advmame and advmenu there were some 64-bit fixes just released (changelog says it now "works")... I will then test it, and upload it to my webspace (hopefully some time soon).
As a side note, anyone like to do their pages locally? I've been working with docutils and trying to make a very clean simple site. However, it's proving a bit tedious... I'd like some sort of local wiki that generates xml html pages, then just use sitecopy or ftp it... It should be easy to customize the page to make it very accessible (follows standards, simple design, dynamic resizing, etc)... My pages are mostly static, running all the fancy stuff server side doesn't appeal to me... Also, not having to use a database would be a plus too... Thanks!
EDIT: Both the latest advmame and advmenu work flawlessly now! (advmame .99 worked for me before though...)
