This one goes out to all of the Resident Evil fans out there, especially those with a NegCon (Sorry, a bit of a joke some people seem to have missed). This tech demo was developed by Raylight Studios as an engine test to show off their shiny technology. This demo, along with a Street Fighter and a Metal Gear Solid demo, popped up on YouTube quite a few years ago.
Shacknews recently posted a story regarding a Diablo port to the Game Boy Color or Game Boy Advance. In the interview with David Craddock, who is writing a book about Diablo history, it was said that the game was to feature three separate versions, allowing players to trade between them as in Pokemon.
This is all great information, but it really only confirms what we already knew : Diablo was being tested on handhelds. Back in 2008, I was able to purchase an early tech demo of Diablo running on the original Game Boy handheld. It didn’t feature a whole terribly lot : An animated menu, some walking around in a dungeon, and the ability to swing a sword, but there it was, as real as could be. If you haven’t seen the screenshots of the game before, I have added some to this post. It was looking quite nice, even as an early tech demo!
