The problem with just leaving the ini file there is that you get the black screen problem.
That's why I think deleting it before loading ES and copying it back before ES loads RA is the best solution unless someone cleverer than me figures out why the blackscreen occurs.
I think I have confused things for you by using variables in the paths. Check the megadrive run script again.
cp $ESSET/powervr.ini $ESPND/
core=$(zenity --list --radiolist --column 'Select' --column 'core' FALSE "$pico" FALSE "$genesis" --title="Megadrive")
This is
cp...
It's not quite working with the powervr.ini. It loads ok but the powervr.ini is essentially doing nothing :/
Putting the powervr.ini in the root of ES app data folder fixes the tearing but causes the black screen as before.
I'm surprised you don't see any tearing - easiest way to notice in ES...
I added:
killall emulationstation
To the snes run script just before the zenity dialog is displayed and this does work around the black screen when using the powervr.ini.
However, I couldn't seem to get back to ES after, no matter what path structure I used in the call to the runES script or bin...
Yes I did try that, but the only place it appears to do anything is in the Base of the appdata folder for ES. Obviously with the previously mentioned blackscreen problems. In the .emulationstation folder, the tearing is there, although I'm not sure why.
Pretty neat. I've been trying this and found I couldn't get anything working...
It turned out that it was the powervr.ini that I had copied in the appdata to fix tearing. It fixed the tearing in ES but causes problems when launching roms. Sometimes it kicks you back to ES and sometimes it...
Well I think @canseco is currently porting releases of retroarch, so I would have a chat with him for a collaborative effort?
Doesn't stop you extracting the PND and getting things working in the meantime! ;)
It's only a guess but it sounds likely that Emulation Station is hogging the gl driver.
I guess in the launching process ES should be told to kill itself as it launches the emulator and started up at emulator exist?
Sure!

The implementation is in c++ so I was looking into the possi8bility of using our optimised neon asm versions within the filter. (https://pyra-handheld.com/boards/threads/neon-scalers.65538/)
I gave up trying to optimise the shaders. I instead began investigating the soft filters.
Attached are the neon soft filters contained in the retroarch git compiled for pandora. extract them to filters and change them using the video menu. It includes scale2x which seems to be running fast...
Thanks for the responses!
How is the scale2x shader on https://repo.openpandora.org/?page=detail&app=NESemu_ptitseb working so well?
That's all I'm looking for and I like the idea of having a unified experience, plus it's easier to synchronise save data with my RaspberryPi and phone if I also...
