@fuchsiii @nixCraft #Funfact: There were modded Gameboy setups that provided output to a TV but those were purpose-built kiosks / demo stands and AFAIK they were never sold and the few that weren't scrapped are extremely expensive collectors' pieces.

As for modern #Gameboy #ScreenCapture, there's the #GBinterceptor by there.oughta.be:

I bought a #gbinterceptor #capturecard
for my #GameBoy. With it I can finally livestream and take part in official #GameboyTetris #tetristournaments.
I have hacked my #gbinterceptor to be an #LcdMirror. I used an Arduino Nano with an HD44780 compatible dot-matrix display as the DUT. The display data is reproduced in the #RP2040 and streamed via serial (USB CDC and UART0). Additionally recreating the display content as video stream would be one of many other additional ideas. So far no gbinterceptor firmware reused, "only" its hardware. 1/

@gameboyscene @ganonmaster @DiConX @ferrantecrafts They arrived today and both seem to work at least USB-wise. No Gameboy here for testing though.
(I can run the firmware on a plain RP2040 which is also recognized as USB video device, however it does not stream the idle screen. Probably because it's not running the TinyUSB task properly then.)

Großartiger sympathischer #37C3-Talk zu einem #Videograbber, der zwischen #GameBoy und Spielmodul gesteckt wird und aus den ROM-Zugriffen auf das Modul den Bildschirminhalt rekonstruiert und als USB-Webcam an einen PC liefert:

Dabei kann nicht auf das VRAM zugegriffen werden sondern der Bildschirminhalt muss aus den CPU-Instruktionen zusammengebaut werden.

Die #MJPEG-Kodierung mit #RP2040-Hardware-Statemachines ist ebenfalls eindrucksvoll.

The talk's recording is online now. If you're even slightly interested in how to get a lossless 60fps #UVC #MJPEG video stream from a #GameBoy by watching its memory bus with a commodity #microcontroller, go check it out:

Also, the slides are beyond beautiful.

Thanks, @DiConX!

I'm still blown away by this.

"We can stream 160×144 pixels at 29fps and lossy, _or_ we can stream 1280×1152 at 60fps and lossless. Oh, and did I mention that we're doing this from an #RP2040, which _also_ keeps track of all memory bus operation in a Game Boy and reconstructs its VRAM at the same time."
