Comments apply to both games code, seems like a lot of changes to just silence a warning?

uint32_t is not unsigned long on all platforms.

I don't think this is equivalent?

The long type needs to go as its width varies between platforms but it should just change to int to match the ra code?
|
It's not only to get rid of the warning. Obfuscate() currently operates on an int, but in TD returns a long (unlike RA, which currently returns an int). Comparing that to a constant like 0xF7DDC227 may fail if the function actually returned 0xFFFFFFFFF7DDC227 because it was sign-extended to long. The only safe way is to declare them to return unsigned int (or uint32_t in this case), since this is what they actually calculate. |

I'd be happy to see it changed to unsigned int in both cases. |
