Am actually running the windows version of fceux using wine. It works fine though not as perfect as the native version.
the subversion url is: svn checkout http://svn.code.sf.net/p/fceultra/code/fceu fceultra-code
this can be seen from the "code" section of the fceultra project page: http://sourceforge.net/p/fceultra/code/
i wanted to post this and confirm this because the url has changed -- sourceforge has upgraded their software stack and the fceux svn url has changed in the process. you WILL need to recheck out fceux with the new URL to get the latest code.
Just built FCEUX '2.1.6 debug' (i386) from the link above. Seems to work better than my previous install (2.1.0). Only problem I seem to have is when I click on something under Options, it crashes and I get the following error:
Code:./fceux: symbol lookup error: ./fceux: undefined symbol: gtk_combo_box_text_new
fceux --inputcfg gamepad1
That dialog should work without issues on any more recent versions of Ubuntu (at least natty). I've just now added some code in subversion (r2542) that hides the "gamepad config" option on older versions of GTK, preventing a frustrating crash in the middle of a (unsaved) emulation session.
Let me know how you make out with the most recent revision. FYI the subversion repo has officially changed, please use the repo as described on the sourceforge page:
If you run into further issues let me know; I'm trying to get as many bugs ironed out before the 2.1.6 release as possible
