6-Pak
From Sega Retro
Are we sure that the cardboard box version is Asian? It says Genesis, whilst it was known as Mega Drive in Asia. Googling "6-PAK Genesis" in Google images brings up pictures of carts some of which have a "not for resale" variant (they both have ESRB ratings). So maybe this was just a late bundle in the US (or possibly some other NTSC-U country in the Americas).
That brings me onto to Mega Games 10, it uses a Euro cart without a cartridge lock slot, so wouldn't be compatible with Asian MD1s. This must have been only bundled with later compatible hardware (which would also explain the lack of PAL/NTSC sticker on it).--Pirate Dragon (talk) 15:56, 29 July 2016 (CDT)
