Because of the lockdown I did use my idle hands to setup a tournament between (emulated) dedicated chess machines and stockfish* (m68k-binary)running on a Macintosh Quadra 800 (qemu-machine) with the help of cutechess(-cli).

Questions:
-What would be sane time-controls for the dedicated machines? 30sec/move?
-Do they ponder, when invoked through cutechess (cpu-usage indicates it, but I doubt it) even if the settings (like 'Aktivschach' etc.) have not been entered through the chessengine-for-mame-plugin from Sandro Ronco (a hero!)?
-Is it possible to play with opening files (with cutechess the moves get executed too fast I suppose for the lua-based chessengine for mame) - mind you: linux only/no wine etc. solution please?
-Why does cutechess complains if "-wait 2000" or so is entered? Why can't it wait 2 seconds or more bewtween moves, or can it? What does it even mean ('operator's time'?)?
This gets continued nevertheless: TascR30/The King 2.2 vs The Stockfish m68k now (40 moves/40min)..
