It seems that Retropie does not currently handle dual monitors. I am going to try a few different options. Maybe loading the Pi right into Mame, or maybe start an OS with retroarch and load a core.

More to come….

@danturn I made the switch to lr-puae2021 recently on pi4/pi5 on Bookworm.
Had to adjust a few core options initially, but plays well.

@mitu I don't remember I haven't booted Linux on arcade in a while. Sorry.

@Lolonois
Thanks for some more directions to go, as yours seem WD targeted i will begin with them in my troubleshooting process.

I was unaware that there was a particular issue with some pi4 models that forced me to use an official pi4 power supply. Perhaps I should attempt this first to resolve my issues or start here to eliminate the possibility.

I have just received my external usb enclosure and have shucked the drive. To my disappointment the drive has no data interface and in fact has an integrated USB interface.

I suppose to proceed with even considering putting this in an external sata enclosure I would have to match this hdd model # with another that has the actual sata interface pcb to use as a donor for this drive. I’m not even sure how well this would work but in theory it should. Does anyone have any other possible work arounds for this issue? I don’t even know when they started doing this, it used to be buy an external shuck it and put it in whatever device you chose.

Does anyone else have any input thoughts or ideas with this?

This has quickly gotten way over my head….maybe I will just buy a different hdd and move on I don’t know yet.

@roslof Do you have a folder with "lr-mame" 0.278 for rpi5 64bit that you can share? Thanks

@BlackLord
note : my understanding is that this modified genplus-gx core is breaking some stuff, so it is not recommended to replace the original genplus-gx core by it (which is probably what you did)

@mitu thank you problem solved:
Deleted 1st partition (unused 16mb)
And now /dev/sda1 is correctly mounted ...on my hdd2...465gb
Retropie boots quickly and without warnings.
Thanks

For the record the 'X' button on my XBox360 Controller is detected as 003 via hypjsch

So I doubled checked that against the Joystick API config:

KEY_BUTTON2 = SDLK_LALT 0 3

And again 'X' was FEET and played fine.

@BurndtJamb said in help installing screen driver on pi zero 2 w with retropie:

. I can't get ssh working since i don't know the ip address due to not having a screen. is there either a way I can install the necessary stuff without ssh?

If you don't have a direct interface (i.e. monitor + keyboard) to the RPI, then you need SSH. If you don't know the IP, you can try connecting using the hostname instead - for the RetroPie image the hostname is retropie (you can also try with retropie.local)

@duglor

The only thing I can think is to enter the runcommandmenu when you start a game and try to select a different resolution.
Really a long time ago since I used this stuff and no time to look into it.
Might be that someone else has an idea.

Please include all the info requested in https://retropie.org.uk/forum/topic/3/read-this-first to be able to assist you.

I just started to begin with DSi Emulation, using lr-LemonDS, and came to the point the tutorial ends: games will only start via the DSi-Menu, so "boot directly into rom" has to be disabled in the core-options.
Only difference: i have full access to the DSi-Roms in the /ROMS/DS-Folder from there and dont have to use prestuffed NAND-Files (would also be a fishy way imo, not the way it should work)

And this is an issue:
first of all on the official FAQ-Board it is recommended to keep this option at its default (=off/boot into rom), in special when the DSi-Bios is used.

Secondly the Retroachievements for DSi-Games only launch up when booting directly into the rom, you can see the widget, everythings fine.
Only problem: the screen keeps being white and silent.

Booting into menu works as mentioned, so the BIOS-Files are good for sure.
I can start all my games from there, but without Retroachievements Support, so i hope to find a way to boot directly into the game (as it should work :)).
I allready tinkered with further core-options, but had no luck.
If anyone has an idea it would be much appreciated.
