    Default Raspberry Pi as HDMI adapter for Amiga?

    Would if be feasible to use the Rasperry Pi's GPIO interface to capture Amiga's video in all formats (including NTSC50) and output to HDMI? I know nothing of programming or how said interface even works so apologies if it's silly question.

    No other options really work for what I want to do. I have a GBS-8220 which doesn't seem to handle PAL (or NTSC50) properly (though I'm sure it could be futzed with more). I need my CD32 w/sx32 PRO to be portable, useable on all sorts of NTSC televisions (as I'm not going to lug around monitors every time we want to play miggy stuff).

    Highly unlikely the way you plan to do it. The thing is, the GPIO does not actually directly support video input. Yes, there's webcams for the Pi etc, bu there's circuitry involved before a module is plugged in. Had a look at various Pi forums, and my understanding is that you need a video capture device supporting Linux. But before you go out and buy something, make sure you read what other people had success with, just to be on the safe side. I'm talking about USB dongles that capture video.

    Even if you could do this, I'm sure whatever latency it introduced would make it an unsatisfying experience

    That's a shame.. I guess in my mind I'm thinking that any electronic input can be programmed to interpret signals of all sorts. But again, I've no clue how any of that works.

    thats is "freakingly" cool no pun

    elcheapo HDMI for an Amiga.

    Would be cool if the push on over the chip method ( like the vampire ) for an A600 or even the Lisa chip.

    have you got a photo of the inside of the A600 where it fits ?

    will it collide with an over the cpu ram expansion ?

    where can i get one

    oh. P.S.

    does 50hz work with smooth scrolling ?

    Only on the A500/+ as the denice chip has to fit into the adapter and the RPI zero's gpio header fits into the adapter.

    My biggest question/concern.. can the black bars be filled with something during the process to keep the aspect ratio intact? Like the sides of a 1084 or something... Or just any logo/graphic.
