Again I made my own FPGA core version based upon YQ100818.

Release FSB100820 provide following changes and additional feature:
- Bootloader color and OSD transparency altered.
- Power-LED turn off completely
- Memory config affect instandly without resetting the Amiga (use with caution)
- EHB (32 sub colors) is disabled in OCS-A1000 chipset mode (for nostalgic reason)
- Floppy step sound simulation available via speaker/buzzer at Spare-I/O pins 5+6
- Keyboard reset also possible via Caps+Alt+Alt keys

Obsolete file removed, please use this release

Im also working on another keypad function for a normal/permanent joystick fire button ("."/DEL key) even when auto fire mode is active.
In Turrican its hard to use the surround-beam, it first require auto fire disable.

As usual, its not very easy to make its way through somebody elses source code ;)

Thanks for the report.

But it seems I still need more practice in Verilog ;)

Release FSB100822 (all listed feature of former FSB100820 release are also present here)

New feature added:
- keypad joystick permanent fire at key "1", even when autofire is set active (done for Turrican)

I found the keypad "." too hard to handle while playing a game.

Handling: As long as keypad "1" is pressed, the fire button keep aktive and overlays autofire. It also affect real joystick at port JOY2.

If there is any error/problem, please let me know.

Attached file again contain FPGA binary and full (additional documented) sources.

It seems there is a sporadic keyboard problem present in FYB100818 and my own released core file.

In some cases the connected ps2 keyboard went totally dead (unuseable) at startup or after a reboot of the AmigaOS under Kickstart 1.x. This can be temporarily solved by entering the OSD via MENU button on the Minimig board and trigger a reset there using joystick.

If any Minimig user has big trouble with the keyboard, I will help out with an adapted FPGA core file. Just contact me.
