EXCLUSIVE INTERVIEW WITH JAMES BUNKER is some top-notch tchotchke material.

From NintendoLife:
Pre-Orders through Dec. 19th:According to Retro-Bit, there won't be a digital release of the game on modern systems, and there are no other plans for more reprints – so once it's gone, it's gone. As noted above, a donation from each sale will go to the Video Game History Foundation.
Retro-Bit has also confirmed that the cart will be compatible with North American and PAL consoles, as well as "most" third-party consoles that are able to run Genesis/Mega Drive cartridges. However, due to the shape of the cartridge, it won't fit in Japanese Mega Drive consoles.
Retro-Bit also states that the cart uses a 5-volt chip "to retain your console’s performance" and that its edge connector is bevelled "to allow for proper insertion without damaging the pins in the cartridge slot". This might seem like an odd thing to mention, but other re-releases – such as Gleylancer – came with unbevelled edges.
