It is quite simple to work with MAME-engines in version 3. But I have trouble adding the Polgar engine. Tried it a couple of times, but it does not work (for me only?).

Anyone else had a try?

Hello Henri,

Just tried Polgar (that I own) and get frozen at Engine Set up. I guess my rom is not compatible with mess 225 (it was working in Picochess 2.01)

I don't know how to figure out if a rom is compatible or not.

Regards,

Etienne

Henri,

Did you check that your rom was actually in the roms folder? I am using Filezeilal and I thought I did transfer the files but it wasn't actually the case . The roms folder permission need to be changed (chmod) to enable to write the files

Now Polgar is at work: at least one sister.....

All the best

Hi Etienne,

Yes I have checked. I already added two other roms of computers that I own in the folder and they are working fine.....

Maybe you are right about the compatibility of the rom. Shame.

Hi all,

It’s working for me, although starting it manually does give a warning message:

Al@RPi4-SSD:/opt/picochess/engines/armv7l-MAME $ ./polgar

Error opening translation file English

Warning: -video none doesn't make much sense without -seconds_to_run

But it does respond, here’s a link to a quick video before I have to remove my Revelation II etc from the dining room table for XMAS dinner. It’s the only day every year when it’s removed, else it’s always up:

Sorry for the noisy kettle, the misses talking and for the poor quality of video overall ...

Merry Christmas

The unexpected answer by Randy was in another thread in this forum: You also need the file 'hd44780_a00.zip' in the roms folder.

You can find this file here: https://www.retrostic.com/roms/mame/hd44780-a00-53665

Thank you Randy, I never would have figured it out!

Hi Henri,

If you start the engine manually when you have a problem, it normally tells you what’s wrong, as in Luigi’s case, it showed that the hd file was missing.

Cheers,

Al.

Hi Al,

Thanks for the advice, learning ALL of the time here! :)

Huh, hope your Revelation II is back on the dining room table again, where it belongs! ;)
