Huzzah! After a little bit of grep and quite some trial-and-error, I found:

$ xinit -- vt1 -keeptty

(Side note: while this works, it uses a small corner of the screen. How to make this full screen?)

With that, I was able to use xinput list and list-prop and get the device name and properties unique to my setup. This led me to:

$ xinput set-prop 'USB Optical Mouse' 'libinput Accel Speed' -0.25

This immediately slows the on-screen pointer by roughly 25% (acceptable values seem to range -1.0 to 1.0, and default is 0.0).

Alternatively:

$ xinput set-prop 6 275 -0.25

...also works, if I were confident the device number won't ever change. I don't know what happens if I reboot, or plug/unplug additional devices etc., though, so I stick with using the name.

Now, starcraftr.sh:

#!/bin/bash xset -dpms s off s noblank xinput --set-prop 'USB Optical Mouse' 'libinput Accel Speed' -0.25 matchbox-window-manager -use_titlebar no & cd "/opt/retropie/ports/starcraft/data" && ./starcraft.sh

(The trailing & used in the example was not necessary)

This worked, but still a little fast and so I dropped it down again to -0.5. Now that feels more like what I'm used to.

Now, let's say I am a user who can't or don't want to alter the root-owned starcraftr.sh in the install folder. Or, maybe I just don't want to lose my custom setting to a reinstall. So I copy it into config dir at /opt/retropie/configs/ports/starcraft/starcraftr-slowmouse.sh, make the edits there, and then edit emulators.cfg like:

default = "starcraft-slowmouse" starcraft-slowmouse = "XINIT:/opt/retropie/configs/ports/starcraft/starcraftr-slowmouse.sh"

Let me repeat my previous question - do you have a system override where the RetroArch settings are different for the gba system ? Is your gba system's configuration file custom/different from the default that RetroPie installs ?

Post the config file (/opt/retropie/configs/gba/retroarch.cfg) on pastebin.com. If you can, get a verbose log from RetroArch during this occurence and post it also on pastebin.com

@harelnaveh10 How did you solve it ? Other user that may encounter similar problems may learn something - so as we, that tried to diagnose and provide assistance.

@retropieuser555 @windg thanks for all the responds i solved the problem

Even though unlisted, xdf seems to be supported by the libretro px68k core. You can add the new extension as explained here:

create the /opt/retropie/configs/all/platforms.cfg file (or, via file shares, at \\retropie\configs\all add to the file: x68000_exts=".dim .hdf .hdm .2hd .d88 .m3u .xdf" reinstall the lr-px68k libretro core.

Copy the .xdf floppy image to the system's folder and restart EmulationStation.

EDIT: as an alternative, if the game has multiple floppies, you can create a playlist in .m3u format and load that instead.

@retropieuser555 I got some errors running cmake. It's fine. I'll use cmitu's incomplete script.

Did you try to login with the lowercase as retropieuser555 suggested you?
Login: pi
Password: raspberry

It looks that the system don't set to boot first into emulationstation, it's something that you can fix if something else didn't happen.

You can connect from SFTP or with Samba and take you files, see: https://retropie.org.uk/docs/Transferring-Roms/.

Or maybe can have an exemption condition to the retropie gamelist.xml
@Lolonois

@mozvillat Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Get a verbose log from the error run and post it on pastebin.com.

@spannernick1 Dude, retropie works without doing all that... only install with the script for debian and derivatives

OK, I finally got it fixed. and I really should have looked at this first, so I'm sorry for putting everyone who looked at this on a wild goose chase. But I've been putting off working on this because I've had other projects and while I can rebuild, I didn't want to. But the overscan didn't work, it would not pull it to the left like I wanted, I made sure the TV was on game mode and not stretching or adding any post processing. I had a spare TV and wanted to rule out the TV, and behold I seen this

I commented out the hdmi_drive=2 and it all works.
I'm not even going to pretend I know what was going on, but my guess the damaged connector was pushing sound through what was left working of the cable and had to push the video to the side to make room for that. I dunno, but new cord, and verified it's working. I'm going to buy some backup HDMI cables just in case and really try to come up with a better solution to where I sit the Retropie

@quicksilver I know this is an old topic, but the link seems to have changed. I was looking up the information for this issue and found this:

@mitu Hello,
Thank you for the suggestion, we will try that and keep you posted if it does not work.

@windg thank you, I will try that asap.

@SaltyApple said in RetroPi UI Falis to load for school project:

After running the lines of code at startup, the program will ask to configure a gamepad once completed it will take me to the screen where you are able to imput code,

That's the command line, you don't input code there, you just write commands which are executed by the shell.

I am unable to get past this screen to access the normal retroPi UI, with the game selection. I've tried re-intalling the OS on to the SD Card but to no luck, it's the same result. I've spent hours imputting sudo commands to allow the retro pi to boot to the UI, but to no avail. i am unable to format the usb as I can not access the standard settings, only the limited system settings. Is there a reason for this.

Not sure what commands you tried, but the UI (front-end) is called EmulationStation and can be started by typing emulationstation at the command prompt and pressing enter (execute command). Do you get an error when you execute this command ?

I apologise for any details that i may not not included, I'm very new to rasberry Pi, please ask for any info that is necessary if you are able to help.

See https://retropie.org.uk/forum/topic/3/read-this-first - provide the info requested in that topic.

Please fill out the info requested in https://retropie.org.uk/forum/topic/3/read-this-first - what Pi model ? RetroPie version ? Power source used ? etc.

The only crash I've seen in the last few years with EmulationStation was related to controllers disconnecting/reconnecting due to faulty USB connection or due to insufficient power fed to the Pi. Run emulationstation by typing emulationstation --debug at the prompt (after it crashes) and then post the error that it prints on the terminal after it crashes the 2nd time.

@antonlamers that's the output of function retropie_welcome which is defined in file ~/.bashrc and is called at the end of that file.

Issues solved.

The problem was that emulationstation didn't have permission to right to /opt/retropie/configs/all. All keybidnings are working fine now.

@StuMcBill I’ve managed to get it working somehow! No idea how.

@Arcuza I don't think that's quite correct. The SD card will have a few partitions on it already. 1 of them is readable by windows, the others are not. The Boot partition should be readable by windows.
