Sorry for the Necro post but this is kind of related. James & Mike Play Godzilla for Turbo Grafix PC Engine (aka Turbo Duo in US) .
Now keep in mind its their first time, so thay don't play it well, but tis a fun watch. My friend actually has the English verison of this game, and we were able to get to , and defeat Super Mechagodzilla (the most difficult ending)
The the next year, I got the follow-up game for Super Famicom (before it was teased in Nintendo Power for SNES, but never released) .
