I was happy to see Wolfenstein 3d on GOG. Is there any chance GOG would get the original Wolfenstein for the Commodore 64?

I know they love using DOSbox but the Commodore 64 would need a different emulator. It would be nice to play it again.

It also opens up a new world of "Good Old Games" to choose from.

Hey it looks like there was a MS-DOS version.

I remember playing it on the C64 so I just assumed that was it.

You can get it from any number of sites. Archive.org has it on page 1 of its commodore section:

If I'm not mistaken, emulators need access to the original OS file in order to run games, which would be illegal to distribute without acquiring the rights for that first, if possible at all, and selling ROMs only to those who still own a C64 would probably be "too niche" for GOG. So chances for a GOG release are very slim, I would say.

The presence of the original OS is not a requirement for emulators.
As far as the game is concerned, all that is needed is for calls into the OS or to the hardware to behave as the software expe

DOSBox, an emulator used by dozens of games here, does not contain MSDOS (although you can actually run MSDOS within DOSBOX if you so desired)

WINE is a tool for linux to run Windows apps, and it certainly doesn't ship with its own copy of Windows.

Perhaps you may be thinking of Virtual Machines such as VirtualBox or VMWare, which require a client OS.

I think he may have meant to talk more about emulating the hardware, which often needs ROMs in place to do it (e.g. if you emulate a PSX, you need the BIOS ROM to do it). Distributing these sits somewhere between grey and illegal. I'm not sure if you can do a C64 without BIOS or other hardware ROMS (given the simplicity of the system, you might be able to). Otherwise, you'd need a licensing agreement with whoever now owns the C64 IP.

This is correct.
The C64 needs three ROM files for emulation perposes. I think Cloanto still owns the licence to them.

Definitely a question for GOG, Bethesda, and Id - as long as they are the ones who own the rights to this; and could port this over to Windows and all.

The page does load the game but I can't find a control scheme anywhere. I've been pressing random buttons and my dude keeps walking into walls and falling onto the ground.
