In Raspi-Config, Select Advanced, Overscan and then Disable. That should allow your GUI to extend to the edges of your screen. if it's still not to your liking you'll need to change the Overscan value in Config.txt in the /boot partition on your MicroSD card.

@delirium_cordia RetroPie (and the Raspberry PI and other SBCs) are all about tinkering and learning new things. No need to rush things if you're not in a hurry - ask away in the forums if you cannot find the answer in the Docs.

@mitu Integer scaling fixed it. Thank you, good sir. :)

I believe these are the lines you need to look at. In this file --> dosbox-SVN.conf Found here --> /opt/retropie/configs/pc fullresolution= aspect= scaler= Use your monitor's native resolution for the first option. Use aspect=true, if you want the correct aspect ratio - after scaling. False, if you want it stretched to fill your monitor. scaler=XXXX - XXXX=your scaler of choice...none, normal2x, normal3x, advmame2x,....etc... Use this to scale the image.

@BuZz said in MAME 2003 "vector" games only displaying 1/4 of screen after updating - what needs to be edited?: BTW the vector games did work on the last binary so it may have been a core option affecting this. there has been some fixes since then though including some relating to the new vector code and the settings, but the last binary is not "old" (It's from the 11th October). I will update the binary though. Thank you @BuZz if there are still problems with vectors in mame2003 after this binary update I will work to resolve them.

@corbidorbi said in Need help making GB screen smaller: Of course that's buried in a bazillion other lines in the .CFG. That's because you enabled 'Config Save on Exit' and all the configurations have been dumped in this file. You shouldn't do that, core options are saved by default (in a separate file) and for other options you use 'Save Core Override'. Replace the retroarch.cfg file contents you have now in the gb folder with input_remapping_directory = "/opt/retropie/configs/gb/" #include "/opt/retropie/configs/all/retroarch.cfg" After that, start a game and use the RGUI to change the Video Settings, but use the Save Core Override option this time. Re-start the game and see if the changes persist. Hint: you don't need to download the file from the RetroPie system, just use Samba Share from your Finder to open the \\retropie\configs\gb folder and edit the file directly.

@juicebag85 please fill out the information requested in https://retropie.org.uk/forum/topic/3/read-this-first i ask because this behaviour (one core doing one overscan behaviour, another doing another) should not happen in standard retropie.

same here, any tip? SOLVED: Start Residualvm Enter graphics Check override... And full screen ONLY Quit Restart emulationStation Cheers

OK I don't know if this is the best way of doing this but it seems to be working. The new config files were saving to configs/all/retroarch/config. The retroarch file being looked at is in gba/retroarch.cfg. I simply copied the content of the new config file and overwrote the content in retroarch.cfg with the new data. I kept back ups of the original files in case anything goes haywire. So far it seems to be just fine. Thanks.

@mviars Yeah, I am using SCUMMVM and getting back in to Riven after transferring my 5 CDs that dug out of an old box. It works great. Fullscreen is working fine but it does leave black borders on the left and right sides which I expected. I am using defaults for video and render, but messing with some of the scale settings yields interesting results for games like DOTT and Full Throttle. Some settings slow down the interface. I am basically using default and OpenGL. This works great with my 8bitDo bluetooth controllers too. Analog stick moves the cursor. Myst/Riven is pretty fun on the big screen and comfy chair!

Hi all, So just to clarify you are saying its possible to: Disable the overscan via raspi-config to get rid of the black border Enable the overscan_scale=1 in config.txt I did these steps but ES still had its own ideas. Could I use the manual settings in config.txt for the left, right, up, down etc values to re-centre it. I also noticed that with overscan disabled my MAME games get cut off at the top a bit as well. Is there a preferred option I should be setting the display settings to in the rasp-config. I have a 55"4k Display. Thanks, Dwarfboysim
