Wilhelm - you'll find that there are other engines that won't run on Ryzens as well.

Capivara, Rodent and FrankWalter immediately spring to mind, and there might be a few others as well.

[Wilhelm]

Yes, you are right Graham, a lot of engines. Crux, Francesca Mad befor 0.15...
Most problem I run into was that the engine is starting but stops during the game. They hang in ram or closed. Most of them run without any problem in a virtuall WinXP machine.
Retro engines need Retro Pc's

Zappa Mexico II does this.

Hmm, the 32bit version runs with no problem here, it's in my rating list. The x64 give me the error "no protocol supported".

Made a test in Arena-Gui and here the x64 version works. Seems there is a problem with Banksia-Gui too.

Well, try a ponder-on match with the x64 version and it will at some point just stop thinking and lose on time. Not every game, but many. Another user has confirmed the same thing.

I could initialize ZM II x64 in Banksia v0.53! Then it works also in newer versions of Banksia! Very strange.
Now I run a 50 game test against Komodo 1.0 with ponder on. Got no errors. If there is an ini file in the Zappa folder delete it try again (make backup). This was also a prolem with Zappa 1.1.
