Hi all!
Since all custom themes on Raspberry Pi are optimized for 720p it makes sense to force the system to run in 720p.
But what happens when my RGBDual arrives and I want to use it? Does the plug and play method still work or does the forced 720p interfere with it and I have to tinker to make it work? It would be great if someone could shed some light on this.
@olivierdroid92 thanks for the info. Glad to hear that this will be fixed in a future release 
Hi all
I'm running the latest Version (8.0) on a Raspberry Pi 4 and noticed that my favourite shader, namely crt-pi doesn't work anymore. I checked the forum and found a thread with a suggested fix:
Downloading shaders.tar.xz from /share_int/, unzipping it and moving all files to /share/shaders/
Well I did that and the crt-pi shader still doesn't work. All files are complete and where they belong. I restarted the system and also tried it on a completely fresh system. No luck.
Is there anything I can do or does someone know what's the problem with the shader?
I really would like to use the shader again 
@glascoyote-0 You have to click on the green button that says "Code" and then you can click on "download ZIP" on the menu that opens. I couldn't find it at first too.
@fagnerpc I have yet to try it out on my system, but from what I have seen here and on youtube I think your theme looks great! Great work!
@myst Thank you for your answer!
When I force Emulationstation to run in 720p, will I still be able to switch to CRT mode via my RGB-Pi cable or the RGBDual? Or does the "forced resolution" interfere with this?
Sadly this doesn't help. I already looked in the documentation and this is the place where I read that the buttons are switched.
It doesn't say how this can be fixed for some systems. As I said I can change the buttons in the Playstation, Mastersystem and Dreamcast retroarch Menu, but on NES, Megadrive and SNES this doens't work.
Would it be possible to use the 1080p version of the theme on a Raspberry Pi 4 with more than 1GB RAM? For example on a Pi 4 with 2GB? Or would I still have to use the 720p version? If this would work, I would think about buying the 2GB Version! I love the next pixel theme and since I want to emulate PSP, forcing the Pi to run in 720p isn't an option for me.
I did a little more testing and actually the remapping works on some systems.
The systems it works on are Playstation 1, Dreamcast and Mastersystem.
But on NES, SNES, and Mega Drive/Genesis the button remapping doesn't work.
Why?
