Although the date and time match, the MD5 hash of my file is 510ed31b0b3c5a33bd822f5db290e00c.
I found that very unusual, because of the matching date and time. So I also did the checksum on the original CD, thinking it might have gotten corrupted on my hard drive, but the version on the CD has 510ed31b0b3c5a33bd822f5db290e00c too.
It could of course be a dodgy CD, but I've been able to play through the game itself without issues. Have attached a photo of the CD (which has the number "S0010304" on it), just so you might be able to see if it is indeed a different release somehow (I'm in the Netherlands - perhaps there is a European version that's different from the US one)?
Welp, make that a corrupted CD!
Having done a file compare between the file on the CD and the resource.aud from the GOG version, there is a difference, but only in that file, everything else on the CD matches GOG's version. The difference runs entirely from 018C3800 to 018C3FFF. Exactly 2048 bytes, which is too round a binary number to be a coincidence, and it is the sector size of a CD-ROM. So there is probably a single corrupt sector on my CD (or the master it was built from)!
In my CD's version, the 303 consecutive bytes at offset 018C3ED1..018C3FFF all have value FF, which is obviously wrong. I'll just use the GOG copy then, and apply the patch to that!
