@JRX88 That's interesting, have to give it a try.

@amolloy said in Display rotation moving forward: This looked promising initially, as the text console was rotated and oriented the way I wanted. Unfortunately, Emulation Station still comes up in the display's default portrait orientation. Then it means the rotation parameters are not used by the DRM system and 'transparently' working rotation isn't implemented. I did notice that Emulation Station has a ScreenRotate option, and I was able to get it to be rotated the way I want. Unfortunately, so far anyways, the same cannot be said of any of the emulators I've tried. RetroArch supports screen rotation, so any lr- emulators should work, see https://github.com/libretro/RetroArch/blob/b89663e213d97894879e2c51fc25b6426ca9ebf6/retroarch.cfg#L272-L284 for what needs to be changed in the retroarch.cfg to get it.

@Gadgetguy said in Best way to do 90degree screen rotate?: Thank you Mitu. So using --screenrotate would affect both emulation station and all the emulators as well? No, the --screenrotate is only for Emulationstation, for the emulators you'll have to configure the rotation on each emulator.

im not sure what your issue is here the tate mode does rotate right this is what arcades do

@edwardthehuman said in lr-mame2003 TATE mode rotation direction?: ddonpchj doesn't run on mame2003, so you're not using mame2003.

@pkg04011979 Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

@langest said in Possible to rotate screen per rom file?: Now I am only wondering, where should I put the rom specific file? As the posts above said - and it's also mentioned in the Docs - , next to the ROM file.

Ahhh yes, I've been hoping for rotation and have been doing it manually. Maybe now ill just use some svgs and throw the rotation at them XD.

@dankcushions said in Cannot rotate MAME vertical games: @sTo0z luckily the issue was in the first few lines :) video_driver = "dispmanx" this is the problem - dispmanx doesn't support rotation. please change to "gl" see: https://github.com/libretro/RetroArch/issues/4898 Yup, that did it.. I'm a fool! Totally forgot I changed that. THANK YOU.

Any luck? Also, (I'm new to RetroPie) what are the steps you took to get the cocktail shader? I've been looking around, but have yet to figure out how to find it, let alone get it running. Help?

@Thorr69 - Just to add to that I think the folder change was to correct a Retroarch Netplay issue and not so much of a core or RetroPie issue/change. If you're using an older version prior to 4.5 like 4.3 or 4.4 it will probably still use the old path unless your update RA then the new path will apply.
