lr-beetle-psx has aarch64 dynarec support, but not sure how viable it is (its arm32 dynarec support is lacking). i think on the emulation side the tide has turned somewhat in aarch64 support and i'm eager to try it.
but yeah, as said because raspbian userland isn't 64-bit it's not viable for retropie at this time, but i am curious how you get on with a ubuntu 64 base image on a pi4. i guess you could compile the mesa drivers from source (if they support 64-bit?), and then modify the system.sh retropie script to use 64-bit compile flags for the pi4 platform. you would probably have to modify many of the emulator scripts which make a lot of assumptions about rpi and ARM support, also.
If you want to set up a new model, simply clone your /home/pi/RetroPie folder to your PC, install RetroPie on the new SD card, delete the new /home/pi/RetroPie folder, replacing it with the existing one.
@mitu Cool! Thanks a million for that I appericiate it. Yeah the wonder of Chineseum arcade controller sets from Amazon... every time the keyboard encoders are ever so slightly different with some showing as something like Micronek (Microtek) and some as Dragon something.
@v-roshpi Contact the seller ? You can download RetroPie from our site, and try and get that to work but you will need to contact them for configuration unless you know what it's using to interface etc
I'm not sure if it's possible to remove a help option, but you can set a blank (transparent) image for the last/first slot of the help buttons row and then shuffle the other buttons left (or right).
You can also remove the mapping for the button from the /home/pi/.emulationstation/es_input.cfg file - make sure you back it up first, just in case editing it goes awry.
The device setup I was thinking would be like this on the raspberry pi
USB1: Usb image boot, raspbian? smaller.
Micro-SDslot: unformatted new microsd (the target of the image write)
USB2: Usb microsd adapter (the source of the image write)
rpi-clone; and I thought I made it sound confusing.
That doesn't give re-distribution rights automatically. There's a topic dedicated to how to legally obtain games/ROMs, you may post there - respecting the forum rules - links to games you think are freeware/demo:
Or maybe I overlooked, or jumped the gun on what was the problem.
If you see the pretty rainbow screen then you wrote the image correctly.
It may be very likely as I was reminded in the forums that there are different versions of the retropie image that will work for the different raspberry pi models. The pi 1/zero are bundled up into one image and the pi 2/3 are bundled into a different image, with older images not supporting the pi3b+.
I don't know about the 1b+
