0002212: Incompatible saves between Intel and PPC Macs-OSX
Save folders going from PPC to intel are not recognized on the intel machine, even if its just a copy of the whole DF folder.
This is probably minor and maybe a unique case. I can only see it interfering with succession games.

I'll see in a bit Intel saves can work on PPC macs

Is save compression possibly not consistent between the two files?

That's my guess -- different compression libraries or something.

This sounds like it could be an endianness issue. If so, fixing it probably would mean rewriting endianness-awareness to the whole save system wherever it uses units larger than a byte.

It's because DF uses fread/fwrite on raw memory instead of dealing with endianness. It also uses longs all over the place, which means converting it to 64-bit would be a lot of work. Pity, really.

Do we still have PPC support? Only info I could found that it was dropped with 31.13. In that case this can be closed.

Yeah, this is obsolete. Thanks!
