Check for mismatches in replays from Gentool Server

[helmutbuhler]

I checked a bunch of replays from Gentool and found some with some strange behavior:

• the replay itself indicates that the game didn't mismatch when it was played
• the version seems to be compatible with 1.04 (version string looks good and ini and exe crcs match compatible retail version)

But when playing it back, the desync message appears. Comparing the final scorescreen with the retail version reveals no difference though.
I found 33 such replays, but compared the scorescreen with the retail version only for 3 of those.

It seems these replays were generated with some incompatible ZH retail version. But to make sure this is actually the case and our repo didn't introduce an incompatibility, we should do one of the following:

• Compare each replays scorescreen with retail version and make sure they all match
• Make sure Gentool reports on all replays that the installation is incompatible (the replays are all from this date: https://www.gentool.net/data/zh/2025_04_April/27_Sunday/)
• Just ignore it and hope for the best?

Here are the replays:

What all these replays have in common is that they use AI players.

33 replays out of how many?

Does this replay mismatch also happen with bare bones EA build and just mismatch message enabled?

I only picked out replays which have AI players in them. Out of about 1540.

I haven't checked, but very likely

Can we see what exact action causes mismatch in any of these 33 replays?

No, sadly retail replays only do crc checks every 100 frames. (and even if they did every frame, you still wouldn't be able to pinpoint the exact action without crc logs)

My suggestion is to check if close-to-retail version claims mismatch on these replays in the exact same way. If yes, then this is simply the way it is currently and we accept it as correct behaviour.
