Which version excactly?
There are several SF2-roms available for MAME as SF2: The World Warriors, SF2: Champion Edition and many more.
Which MAME-Version are you running?
Which Version of Retropie are you using?
@dankcushions Switching the resolution to Mode 16 (1080p 60fps) in RetroPie seems to have resolved the remaining issue. The game takes up much more of the screen and now looks visibly correct while paired with using "Core Provided" for Aspect Ratio in RetroArch.
Thanks for your help, all! I'm still curious why my display settings got all changed around after upgrading to RetroPie 4.7.20, but I'll leave that to people smarter than me to figure out. :)
Pi Model or other hardware: 3 B
Power Supply used: inland 5.25V 2.4A Micro USB
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): I think 4.1?
Built From: Standard; haven't added any images or anything like that
USB Devices connected: Button converted to usb, keyboard
Controller used: none (unless you cant the button and joystick)
Error messages received: no error message, the screen just looks off
Verbose log (if relevant): idk what this means
Guide used: (Mention if you followed a guide): am following and using the parts from this youtube video:
Also looked up how to screen tilt (did the screen rotate 3) and remove black bar (took out the # in that code)
File: Don't think a file is the error, as it works fine on my monitor but not the arcade1up
Emulator: (Name of emulator - if applicable) using the retropi with atari and nintendo
Attachment of config files: don't think its a files issue as per the reason above
How to replicate the problem: to replicate the problem use one of the machines with a vertical screen (Ms. Pacman, for example) and use the parts that are listed in the youtube video: HDMI LCD Controller Board: https://amzn.to/2QlKKfr , Arcade Sticks Buttons and Encoders: https://amzn.to/2ItwRt5 , Pi 3 B
Select runcommand from the RetroPie menu (or through configuration/tools in RetroPie-Setup). Ensure Launch menu is enabled. Check Launch menu joystick control. If joystick control is disabled, either enable it, or use a keyboard plugged into any USB port, instead of the gamepad, to access the launch menu.
I would add that in the /boot/cmdline.txt parameters, I changed the resolution to 768x768 and everything is now centered and looks correct....except, the top few lines of the [TAB] menu in Mame are cut off....
@greenhawk84 to be clear they’re never going to fix dispmanx/omx support. these utilise features of the original closed source gpu firmware that they have replaced with an open, more standard linux solution. it’s not all bad news, though, as there’s typically an alternative solution (eg vlc rather than omx, but you may have to re-encode/replace your videos).
@mitu good point. So one can use rotation of 90 or 270 degrees BUT the width and height is not exchanged on my proposed setup. Thus my hint only works flawless for 180 degree screen rotate installations.
So here I am six months later pleased to report that I finally have got this screen working. Kedei have changed the download page to https://kedei.net/download.html On a separate computer I downloaded the driver as a zip file, which I copied to a USB drive. I then copied the file to /home/pi (in RetroPie) I then unzipped it. This gave me a new directory called LCD_driver. I then did a chmod -R 777 LCD_driver. Despite the page on ali saying do not use FBCP driver I used it with the ./LCD35_fbcp command. The screen now works. I hope this post helps anyone who is having difficulty with this screen.
