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.
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'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))
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.
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?

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 PLN30-PLN40, 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.
✨ Discussion of the DIY-A586 v1.9 FPGA-based Amiga-compatible board by piotr_go, built around a Spartan-6 XC6SLX9 with 32 MB SDRAM, 16 MB flash, HDMI, analog audio, SD, RS232, joystick, PS/2, floppy and A500 keyboard interfaces. The thread covers core architecture (own core with TG68 CPU), compatibility, FPGA resource usage, synthesis constraints, and comparisons with Minimig/MiSTer. A large part of the discussion focuses on assembly and bring-up: flash programming, ROM loading, SD card formatting, Kickstart patches, floppy-drive conversion, Gotek compatibility, SDRAM timing, oscillator choice, and soldering order. Later posts report fixes and updates for Amiga core, SD support, PS/2 reset, floppy reading, audio, and bitplane handling, plus questions about parts sourcing, connector footprints, and possible future ports or expansions such as AGA, C64, Spectrum, and alternative FPGA platforms.
