Deep Junior Yokohama

[gordonr]

I tried it with ponder-on online play for Joost's monthly tournaments. Intel 10th Gen no problems. But with the exact same config on a Rysen 5900X, sometimes it would play a game just fine but other times it would just stops making moves, CPU usage drop to zero, and lose the game. Never got to the bottom of it, but no matter.

Same for me. Intel fine. AMD Ryzen 5950X issues as you describe.

No, I'm not.

I'm referring to the 64-bit version. It works fine on Intel 10th gen but has issues on Zen 3, configured exactly the same.

And can you show how you have the Zappa Mexico engine set up.

See above - another forum member confirms exactly the same issue with Ryzen 5900x / 5950x. That is it from me on this subject. Old engine, I don't care about it anymore. I just use the Intel on the rare occasion I want to use it in Joost's online tournament, to provide some variety and something different in that tournament. Never use it otherwise.

I simply mentioned it to demonstrate the point that Deep Junior Yokohama is not the only older engine that can have issue. There are probably more.

Perhaps you can try with an old version of msvcrt.dll.

From which year is it worth downloading this dll to make it work maybe.

I'd say from around the time the last patch was released, which would seem to be 2013.

Or just take the msvcrt.dll from the Intel computer on which Deep Junior works.

Rodent, Capivara, Crafty (havn't checked all versions) and FrankWalter won't run on my 5950x either.

Do they give similar errors?

They just won't open.

This version is almost 10 years old, and the majority of the codebase probably several years older than that. Older software often does continue to work perfectly fine on modern hardware, but sometimes you have to accept that it simply won't. For me, Zappa Mexico is a case in point. Works on Intel 10th gen, but on AMD Zen 3 it frequently just stops calculating and doesn't make any more moves.

Because you're setting up the Zappa Mexico engine wrong. I also noticed something very important.When I use the 32 bit version, the engine works fine.If I use the 64 bit version it no longer works.

No, I'm not.

I'm referring to the 64-bit version. It works fine on Intel 10th gen but has issues on Zen 3, configured exactly the same.

I use the Zappa Mexico II x64 version now and then, and I have no problems with that one either on my Zen 4800H either. I like using the Dissident Aggressor settings.

It always makes me smile when I see someone using my creation! Good stuff! Glad you like the settings!
