Yup, Genesis is the American name for the MegaDrive. The MegaCD is called SegaCD in the USA. And yes, 95% of cartridge games will run on any region MD/Genny. Unless its a chiplocked game (region lock), then you'll either need a pass-through region cart or just hardwire 2 switches into the MD to choose between 50/60Hz and Jpn/Eng language.
Ok, so Run n' Gunners aren't shmups, we've established that (lots). But they are close enough. Is it possible we could have a separate R&G forum on here? Then all us fans of the Metal Slugs, Contra etc would have somewhere to post instead of here in the Shmups Chat forum. Also, what about a small R&G mini-site attached to the main Shmups.com site?
I really like R&Gs. I've finally got all 6 MetalSlugs on MVS

and I'm looking forward to getting a MD (again) so I can play Contra and GunStar Heroes.
