ZSNES Screen Problem

ChronicKurt · Post by **ChronicKurt** » Tue Nov 13, 2007 2:38 am

I am using ZSNES on my PC which is not that great its only like 256 MB of Ram and Intel Celeron 2.0 processor but any way I bought a brand new Samsung 32" HD TV LCD and hooked my PC up via VGA.

Heres my dilema ZSNES looks great but when I am playing games like final fight or Tales of Phantasia or any rpg or side scroller the screen gets all shaky and sort of bumpy whenever you move off the screen and cause the background to move like in side scrolling beatem ups like Final Fight.

Can anyone help me it woul be much appreciated.

if you mean jitter, there is a option in the programs configuration files to have the emulator always run @ 60hz... then you just enable vsync and the jitter is gone.

or leave the refresh rate and just untick vsync and/or triple buffer to have screen tearing instead of jitter.

do this and it should run silky smooth... turn the auto frame rate to 0 as well.

edit: look for this

; Force Refresh Rate (0 = NO, 1 = Yes)
; Enable this if you are experiencing visual tearing
; WARNING: Setting a refresh rate that your monitor cannot handle will have
; consequences! The DX Refresh Rate Override in dxdiag must be set to default
; in order for this to work! The refresh rate is only valid if it is supported
; by your system! This option is only useful in fullscreen modes.
ForceRefreshRate=1
SetRefreshRate=60

in ZSNESW.CFG and set it to force your refresh rate to 60hz. now run zsnes and turn on vsync. now adjust the frame skipping so that it is at 0 instead of auto.

what are your computer specs? it might be just the game uses something thats not fully emulated yet.

I'll be nice and not put up a franpa alert sign... yet.

My original guess is that the LCD is not quick enough to keep up with the action.

It isn't about the specs, it is more about the latter part of said statement. There are missing holes in the info (but I don't think it is a significant factor except I want to shout FEED ME RAM).

man my specs suck but when i turn off hq filter it runs fine do u think its just my pc?

Somewhat.. if you compiled ZSNES to take advantage of your processor, HQx filter's overhead is much smaller.
