    Amiga has 'PrtSc' under '*'.

    As for the sometimes jammed '`', I still don't know where the problem is. I've tried everything I can think of.
    I'm beginning to suspect that it's some bug in the ROM that sometimes reveals itself at non-standard CPU speeds.

    I used to have an A600HD , then a cd32 + SX1 and this problem occurred as it does here.

    >>21122771 .

    What I mean is, is it not possible to switch the video modes on the A586 to another key, not PrnSc, for example End, F12 or other. Because now I can't exit some games, instead of exiting, the video mode changes, the A586 captures the PrnSc press )

    I didn't even know there was an option to switch modes. Interesting, what modes are available?
    I would suggest mapping it to a shift+prscr or shift+ctrl+prscr combo so it doesn't interfere with anything, because the END is there for a reason.

    The ctrl+alt combinations with F11 and F12 will be occupied by reset and menu (as you manage to squeeze in fpga).
    For PrScr I may add ctrl+alt, but that too as it will fit.

    PrScr cuts the frame around the workbench, or turns on interlacing.

    Added after 2 [hours] 57 [minutes]: .

    CTRL+ALT+F12 - menu
    CTRL+ALT+F11 - reset
    CTRL+ALT+PrScr - change of resolution

    Thank you! And it's still possible to have one, but the "slow" version)?
    And a question about the mouse wheel - AmigaOS 3.2 added support for the mouse wheel, is there any way to force this to work on the A586?

    So now the question is about the NES core - neither the joystick from the NES clone nor the joystick from SEGA (Atari) work. The core itself works and is controlled from the keyboard. Maybe some settings are needed?

    I don't have a gamepad for the SNES, can't I plug in a regular NES or Atari compatible one?

    I am almost sure that the purpose of the key is described here))) I need to study Veriliog)

    Verilog code describing electronic components.

    Hi Piotr_go, is there any chance to get your C64 core for 1.9 board?
    Thanks.

    I'm not going to investigate the gamepad ports on the NES core yet, I don't have time and I don't know Veriliog)))
    But I rewired and connected the NEC FD1231H floppy - It works))

Modified NEC FD1231H floppy disk connected to a circuit board with visible wires and a chip. A pink controller is in the background.

    Maybe in the future. I didn't make the current one available due to source licensing:

    Hello,
    In version 1.9, the keyboard from the amiga500 does not work
    Is there any chance to correct this.

    Hi,

    Can't get ZX-Spectrum core to work properly.
    It loads esxdos, F11 runs menu, but after selecting any file (trd,scl, tap) its either hangs or resets.
    I bet early (7-8 months ago) it ran well,
    Amiga and NES work brilliantly.

    Hi,

    Fresh board, after it starts if I use microsd to sd adapter and press f4 or f10 or ins screen gets black. If I use standart sd card - it is ok, I see the file manager.
    Tried different adapters and microsd cards..the same.
    What could be the problem?

    Thanks

    What µSD cards are you using?

    Different ones. Kodak, Kingston, Apacer. From 2 to 32gb.

    Cards must be >4GB.
    I had no problems with Kingston.
    Sandisk, Kioxia (Exceria), Patriot (V30) also OK.

    Hi,

    All not working cards were sdhc (I) 1 21/20 read/write
    SDHC (III) 3 80/80 read/write are working as expected.

    Thanks.

    I realise how "helpful" this sounds, but in my case U1s work:
    Purple PCB named DIY A586 with various electronic components, connectors, and a SIM card. .
    I have yet to have a card not work.
    Didn't you sometimes buy them on aliexpress/ebay ?

    Yes, these ones from aliexpress, and strange - the only uSD not working.

    SD cards are one of those things you should avoid on aliexpress/ebay. :D .

    I have a suggestion for you and others. let's buy Peter a keyboard and he will add support.
    I have looked on ebay.co.uk myself, there are several options for the price of £30-£40, or allegro.pl or olx.

    I personally do not need an A500 keyboard with DIY, but I can add something from myself because the whole project is free.
