Wrong screen resolution in ES and/or in game.

A. If you don’t have a 16:9 screen or your screen got issues to display correctly, you’ll need to update the config file in the BOOT partition. You can access the BOOT partition by connecting our SD card on the computer. You have to set the correct “hdmi_group=x” and “hdmi_mode=x” value according to your destination monitor. Find the correct values in this list https://elinux.org/RPiconfig#Video_mode_options

Nintendo 64 is showing the games in 16:9 or a wrong aspect ratio.

A. The emulator is already configured to output a 4:3 video signal. Often your TV or monitor will automatically stretch the image to 16:9. You simply have to go in your monitor settings menu and change the “Display Mode” to “Aspect” instead of “Full”. The terms may change depending on the brand of your tv/monitor. There’s no configuration file you can change on the RPI3 itself, everything is already configured.

Neogeo is set in home console (AES) mode. How do I change it to the arcade (MVS) mode?

A. To change the Neogeo bios to arcade instead of home console. Press Hotkey + X and in Retroarch menu Quick Settings > Options > Change “Force Neo Geo mode” option to “UNIBIOS” and also change the “BIOS” option to “Universe BIOS ver. 3.2”.

If this step doesn’t work and you have the issue bringing you back to the gamelist, just follow this manual troubleshooting tip. Navigate to “share\system\configs\retroarch\cores” and modify the “retroarch-core-options.cfg” file at line “fba-neogeo-mode = “AES”” change “AES” to “UNIBIOS”.

Temporary overlays fix for the beta arcade.

A. Some vertical games have a slightly different resolution making it not fit the overlay correctly. You can do them manually 1. Press Hotkey + X button to go in Retroarch Menu. Press back to go to root menu 2. Settings > Video > Aspect Ratio (set to custom) > Adjust the 4 values under Custom to match the overlay 3. Back to root > Quick Menu > Save Game Overrides. You can fix the games you play the most like that.

As for 1942, some vertical games are in 4:3 but they should be in custom. That’s a mistake as we were using a special overlay for that game back then but we haven’t updated the config file. You can add the overlays yourself though. 1. Press Hotkey + X button to go in Retroarch Menu. Press back to go to root menu and then 2. Settings > Video > Aspect Ratio > Core provided (so the overlay doesn’t hide the retroarch menu) 3. Back > Onscreen Display > Onscreen Overlay > Overlay Preset > arcade > arcade-v.cfg 4. Back > Back > Video > Aspect Ratio (set to custom) > Adjust the 4 values under Custom to match the overlay. 5. Back to root > Quick Menu > Save Game Overrides.
