I have the same problem like others, that my zsnes crashes when I'm selecting the HQ filter. I've allready changed the zsnes.cfg from
hqFilter=0
; Set HQ*x level [2..4]
; Recommended min resolutions
; HQ2x = 512x448
; HQ3x = 768x672
; HQ4x = 1024x896
hqFilterlevel=2
to
hqFilter=1
; Set HQ*x level [2..4]
; Recommended min resolutions
; HQ2x = 512x448
; HQ3x = 768x672
; HQ4x = 1024x896
hqFilterlevel=4
The result was that zsnes crashed directly while it started.

I'm using a custom resolution of 1680*1050. Changing the resolution to some lower supported ones didn't help at all.
Has anyone a clue or any solution for my problem?
Thanks
