Would this be of interest & possible..?


It is lovely. I have my doubts as to whether the resolution that the Pandora has is high enough to pull this effect off, though...


(By the by, I removed the earlier duplicated copy of this topic - it appears that this is the later revision, anyway. :P )

You can have those effects in PanMAME already, as they are built in. But it hurts performance a bit :)
 
We have scalers coded to use NEON, so if someone would code that effect for NEON as well, it shouldn't be a huge performance hit.


However, as mentioned above, resolution would be an issue.


The filter works by displaying three pixels (RGB) instead of one.


That would mean, a 320x200 pixel game would need a resolution of 960x600 on the LCD - so it won't work.


So the only thing we could do would be simulating scanlines and the phosphor bloom.


Would make it look a bit better, but not as on the pictures on that thread.

The problem is, that you need a 2x or 3x scale for this stuff to work nicely, as well, as other scaling effects, what hurts performance not by applying the scaler, but from scqling the game itself.


Neon of course helps here, but in PanMAME for example, the screen gets virtually scaled to2 or 3x scale and is downsized afterwards to fit the screen, that costs performance and doesn't look too good, as pixels are reduced. Games that have a native res of 320x240 look great in 2x scale of course :)
