ZSNES problems

[snesbmg]

I can't open zsnes as I set the resolution too high. When I open zsnes in terminal it says:

Could not set 1600x1200-GL video mode.

How do I open Zsnes now?

To get access to the /dev/input/event* devices (to get rid of the 'unable to poll ...' messages) you have to be a member of the group 'input'. You can probably do that from some graphical applet for changing user accounts or you can use usermod from the command line 'usermod -aG input username'.

ZSNES has a configuration file in '~/.zsnes/zsnesl.cfg'. Open that file with any editor, it's human readable and quite well commented. The setting you want to change is 'cvidmode='. It' probable set to '19' now (at least that's what the comments in the file say would be the value for 1600x1200). Try '15' (which should be 1024x768 in a window).

Alternatively you can call zsnes with the '-v num' option with num being the number of a video mode. So 'zsnes -v 15' should give you zsnes running in a window of 1024x768 pixels.
