Proto:Shadowrun (SNES)

Two prototypes of Shadowrun exist: No-Intro lists both "Shadowrun (USA) (Beta)" and "Shadowrun (Europe) (Sample)", though it's not known what differences exist between them.

US Prototype
A prototype with the following MD5:

DGC Portable Phone
The DGC portable phone (which lets you make calls anywhere) is present in the prototype Debug Room and marks the location of the invisible exit. It can be picked up if you can get close enough without getting booted out.

Caskets
The crosses were changed in the final version. There was also a subtle modification to the dimensions of the casket lids.

Europe (Sample) Prototype
An (English?) PAL prototype with the following MD5:

Dialogue
There are occasional instances of "uncensored" dialogue which were cleaned up for the final, presumably at the behest of Nintendo.

"Chop shop" was changed to "morgue", and the bold font on Grinder's name (signifying a topic to ask about) was removed.

The only things held over from the last two lines were "a fox" and a question mark, plus a few letters to help spell "seen" and "before".
