@magzilla This may be a bit late since your original post was in April, but I thought others might be interested as well.

Over on the MiSTer FPGA forums there's been a lot of interest in this display:

https://nl.aliexpress.com/item/1005001689746001.html

It's a 9.7" iPad-ish display that can run at up to 2048x1536(but supports lower modes as well). I bought one and it's extremely good value for money, although you do need to purchase some extras (a better stand, a better video cable are probably musts).

Comes in three slightly different configuration - I got the miniHDMI/USB C version. Very happy with it. So far I've tried it with a MiSTerFPGA, a TheC64 and a Raspberry Pi 4 (running Raspberry Pi OS but I see no reason it wouldn't work with RetroPie)

Here it is running on my MiSTer:

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

Post your /boot/config.txt and /boot/cmdline.txt.

Post Update:
With this command I can display without problem "image-test.gif" in this case, I think the problem is something in the retropie configuration that I can't see

pi@raspberrypi ~ $ sudo apt-get install fbi pi@raspberrypi ~ $ wget https://ozzmaker.com/piscreen/image-test.gif pi@raspberrypi ~ $ sudo fbi -noverbose -T 1 -a -d /dev/fb1 image-test.gif

@mediamogul
It takes a lot of imagination to turn it into a football game , but it was the idea. 😁

Bump
Im assuming this is a brand new problem that no one has experienced before based on the screen I have being generic.

All right I'll try that!

@Impman66 said in Are those Game & Watch Titles (mgw) dumps or remakes ?:

I have quite a few now, somewhere in the house I have the original "Fire" which I have not yet been able to find.

I have a few as well like "ball" and "the exterminator" which sadly are not a part of the madrigal simulator set.

I don't know the author. I am planning to use this build I have as a temporary until I get my keyboard in the mail. BTW how are you always on here? You give replies 24/7! XD

You can connect a second display only over the GPIO - something similar to this setup should get your 2 independent displays - one for normal gaming via HDMI and a 2nd one over the connected over SPI (GPIO pins).
The 2nd display can be used for showing the images (via fbi) or even videos (via omxplayer).

Why not just use a DVI cable. I use this all of the time for old 4:3 monitors

@Amplifuzz

You don't really need a ton of custom video modes, since the resolution stays the same, and you only have seven or so different refresh rates at maximum to deal with. Two config lines like "lcd_native_res=1920x1080" and "lcd_range=50-60" or whatever the monitor supports would cover it.

on groovymame, sure, but raspberry pi only understands discreet videomodes. you have to tell it when you want to use a new videomode. in retropie, using the runcommand, you would have to add each videomode to the list, and when selected they would have to call the api command i linked above (since these aren't videomodes in the raspberry pi's limited list of videomodes)

I'm afraid that the whole 'snap to the closest available refresh rate once the native ROM refresh is detected' part is best handled by the emulator itself, as well.

agreed, but for that to happen someone woudl have to update CRT switchres (or something similar) in retroarch such that it can communicate with the pi's custom videocore API calls (see the link above).

i'm told that you can get crt switch res to work with pi, but only under X. we don't use X in retropie. there's some info on this on the (huge) crt switch res thread over at libretro: https://forums.libretro.com/t/retroarch-native-crt-support

Does anyone know the type of connection on the wires in my first photo please?

Figured it out, there was a custom runcommand script that was being ran during launch of each emulator. Once that was disabled, it fixed the problem entirely.

well at least you gave it a try!
