I've started using Recalbox with the latest Version 4 beta and updated to 4.0 final. All CD-based systems worked in the beta without issue, pcenginecd, segacd and psx. Now both pcenginecd and segacd do not work anymore and psx gives me a message that there will be issues when not using a bios file...
I've double checked my bioses, installed 4.0 final from scratch but the issue remains.
Is there anything that has been changed and that I might have missed?

I have verified that...
-the filenames within .cue files match the case of the actual file
-the files are added to gameslist.xml
-all emulator options have been tried out
-an entry in the log file is present, but doesn't give a clue about what's wrong.
-the systems don't work on my sdcard after the update (exiting after selection) and within a clean new setup (black screen but menus working)

Is there a way to debug my issue?
Any info on this would be very much appreciated, thanks guys!

Hey Guys,
I'm desperately looking for an option to tell piFBA NOT to stretch the image but do an integer-scale instead.
fba-libretro works ok with shaders but many games just don't work (romset verified with CMPro).
So I'd like to use piFBA exclusively on my PI3. I'm using fba.configfile=/recalbox/share/system/configs/fba/fba2x-custom.cfg to enable scanlines, but messing with the few video-options available doesn't help... When I enable my beloved scanlines and the image is not scaled to an integer-value the result is quirky movements every few lines, hope you can imagine what I'm trying to explain?

There's an option in the source "option_rescale" but it's useless adding it to my cfg-file.
Any help with this is very much appreciated. Thanks y'all!

Hey Guys, thank you for all your hard work, I just got into RPi and recalbox, I'm really having fun!
So, I'd like to ask -
It looks like all shaders that add scanlines to the video also add a certain amount of vertical lines to the output image...
is there a shader that only adds horizontal scanlines and nothing else?

Thanks again,
-Alex-
