Nightmare Busters is an unreleased (never even announced, as far as I know) SNES platformer by Nichibutsu with utterly gorgeous, CPS Capcom-like graphics. A nearly complete prototype cart was discovered some years ago, but its owner has never publicly released the ROM. However, Super Fighter Team are finally giving it a cart release with box and manual, limited to 600 units. It won't be shipped until 2013.
Preorders are open. At around $70, it won't be cheap, but that's chump change compared to some of the PCB purchases that pop up here regularly. And it's about what new SNES games went for back in the day, when adjusting for inflation.
The game doesn't look that amazing, but I might get this to own a piece of history. The ROM dump will probably never make it out there for years.
