Title: Flickering Stuff
Post by: Fulg0re on February 01, 2018, 02:02:51 pm
hi there ...

I found 2 Games which have some kinde of flickering problems.
Samurai Shodown 3 and 4.

Character and Lifebar are flickering very strong.
I tried out every blitter and soft fx. Always the same.

Are there other " working" roms out there which do not have this problem ?

Kind regards

A lot of these games use a flickering effect to simulate transparency. Not a bug, but a feature.

As iq_132 wrote, many 80s/90s games use the "flickering trick" to simulate trasparency effects... in the old CRT screens the "flickering trick" has a good outcome, it blends with the intrinsic refresh interval on Cathode Ray Tube (CRT), while in the modern LCDs the outcome is rather mediocre...

Hi Fulg0re,
It's really hard to get this effect (flicker-blur) perfect in emulation, but it can become close. 
Here's some tips to try:
Set blitter to DX9-Alt and enable: Blitter Options -> Advanced Settings -> Motion Blur
or if you don't like motion blur, try enable triple buffer, force 60hz rate and play fullscreen.

bye for now,

Hi there,


i tested it on my Laptop Works perfect no flickering !!!

BUT ...

On my Arcade PC i am not able to run DX 9 Alt. FBA will crash with GURU 3D Error Message.
When i run DXDIAG i can see that DX 11 is installed which is also compatible with earlier DX Versions.
This is the last thing i have to fix but dont know how.


kind regards

Did you try installing https://www.microsoft.com/en-us/download/confirmation.aspx?id=8109 ?
To my knowledge, DX11 is not really compatible with DX9 games, you shouldn't trust microsoft too much.

Hi there...

No it runs almost perfectly !!!!!!!
It was my fault :)

I have checked after receiving GURU Failureinfo the Log. I dont know why but
the DirectX 9 wasnt installed. So i just downloaded and installed it.
After restart i set the FBA as recommended here. Motion Blur and so on ...

Wohoooo !!!!

- No more flickering Shadows of the characters.
- No more flickering lifebars in Samurai Shodown 3 and 4.
- Also nice trancparents WIN Logo in Streetfighter Alpha 2 and 3.

This is how i call emulation close to real !

Thanks for your great support !!!


Kind regards.
