No idea, maybe with LUA embedded in the .lay file?

Meanwhile, Berger dumped a second Blitz version, it's a newer revision.

Well, I've no experience with LUA scripts in a layout file, and without buttons accessible via PORT_CODE(KEYCODE_UP/DOWN/LEFT/RIGHT) in the driver I have no idea how to write a plugin for this Blitz engine.

And there's also an other problem with the cursor keys - the line between pressing these buttons too short or too long is very small:
too short --> no reaction at all
too long --> immediately starts repeating the key

Is there any way to make the reaction on pressing these keys faster and to delay the time for key repetition, or is this predetermined by the hardware?

PS: and a small mistake in the driver saitek/mark5.cpp:
"Black' and "White" should be swapped in the input ports, i.e. it should be
PORT_NAME("G / 7 / White") and PORT_NAME("H / 8 / Black")

Go, go, gooooo!!!

They are 2 analog dials and emulated as such, though MAME provides digital inc/dec keys that rotate the dials by a fixed amount per frame (the cursor keys in this case).

On the real Blitz, rotate the dial faster to scroll through the settings faster. And if you rotate the dial a tiny bit (like tapping the key in MAME for a brief moment), it hasn't moved enough yet to go to the next setting.
