Harrumph.
I saw in a post about importing/exporting settings that there’s very little memory left to play with. But this was in 2017. Don’t know if this is still true. If it is why is there so little memory available ? Surely that defeats the point of having an open source firmware if its paralysed by lack memory ?
Anyway, I’d like to see a way to dump a raw screenshot from what is being sent out over HDMI. My HDTV does not have that functionality and I find it a real pain to have to photograph the screen all the time. Do other HDTV’s have a way to take a screengrab ? I used to have a Hauppauge TV Tuner that could. I could invest in a capture card but only really want to record still images at the moment.
The memory problem was alleviated some time after by rewriting the code for the ”soft CPU” (afaik this is the code for the minimal OS of sorts that runs on the ARM processor).
In any case, I don’t think it’s possible to do screenshots, in simple terms because there is no frame buffer. I suppose there is some theoretical possibility of saving from line buffer, but perhaps write speed sets some limitation. And I also think there is no file system (I may be wrong here). What needs to be kept in mind is that not all information from fpga side is necessarily easily retrievable at all times, unlike more traditional PC emulators.
I am not really technically versed, but I think this may be a case of ”had it been possible, it would have been implemented already”.
