Though I speak no word of swedish I believe they could be cool as long as they are unique? Would love to see more software in german, french, spanish and even swedish. What do the admins think?

That would be nice. If they're Swedish versions of already-uploaded games, just combine them into the same archive and re-upload.
(There isn't much foreign-language material floating around for old Macs ... what's left is mainly French / German from the Vieuxmac Archive, and whatever Apple provides for free.)

That depends. If it's a Swedish Doom-clone, then it's OK because it's easy to figure out. If it's an adventure game that has no English option, then it's a problem because few will understand what's going on.

Well, specify that it's in Swedish and that shouldn't be a problem ...

Ditto what Balrog said. Old mac programs in languages other than English really are pretty scarce on the web.

You'd use Disk Copy 6.3.3 in OS 9 or earlier. But make sure to archive those .img files using Stuffit (available here).

Do you plan to make this work inside an emulator?

If so (your dmg has been added to the emulator's GUI drives list), after booting up the first time the emulated Mac OS will ask you to initialize .dmg images, for preparing issues it's OK. After initializing (this time Mac OS 9 ready - using the emulated Mac OS), the emulated Mac OS will accept it.

Once initialized, you can prepare the disk as you want and there are no problems using it in emulated Mac OS systems (windows users probably have to rename the extension to .hfv).

Or you could use Virtual DVD-ROM/CD Utility.
Works even under Classic in OS X. Produces non-compressed Toast compatible disk images which can be assigned directly to Basilisk/SheepShaver or mounted witin.

@SwedeBear:
Toast images are NOT checksummed either.

@Balrog: where is the claim of checksum in this topic?
