The software you could get from any number of places, probably. The thing you really need is the dongle. As I recall, they were just encoded for standalone (i.e. dedicated worlds) vs upgrade. I don't remember if the upgrades were discriminated (like needs Safari vs needs Open Season, etc.) since that was 10 years ago, so as long as you have a relevant full set (like, the single one for your Safari) you should be OK. It IS a possibility, though. It's also possible that BBH Pro was one path, and that Safari/OS were another path. Mostly just be safe with specifically what kind of World dongle you get.

Dongles are required for all older models you are upgrading from so that dongles aren't orphaned to create new games.

World has a standalone version and upgrade version. Upgrade needs a prior game, Safari or one of the bbhs. For the bbhs, if it was open season, that also has multiple flavors: standalone or upgrade. If upgrade, then it also needs pro and or online. The worst possible case was 4, world, os, online, pro, but it was long enough ago that I can't remember if I actually checked for all 4 or not (but, probably).

I'll assume that's a generic sorry since I haven't worked for Play Mechanix in 9 years, heh.

That wasn't true when I was there, but times certainly could have changed.

If you're talking BBH/Safari/OS/World, the software is most definitely different for standard vs. deluxe vs. whatever the giant one is.

I would ASSUME the dongle is also different, but my memory is fuzzy on that one. It might actually be the same now that I think about it. I just don't remember for sure. But the software is different because the resolution and aspect ratios are different.
