Everything works great! System is boxed in great condition, comes with the "official" wireless controller (launched with the Mega SG, works fantastic and feels great), Model 2 comes with power brick (CD system needs power for proper Sega CD playback!). Including a Football SCD game so you can listen to those hot tracks.
Mega SG comes boxed complete with everything it came with (including system riser pad for the Model 2 integration, as well as the Master System adapter). System is running jailbreak firmware that enables sideloading, including loading other region CD BIOS to enable playing games outside the US region I believe, but don't quote me on that last bit, I didn't have any Japanese games to try this out.
Fantastic package, pretty firm on price. Would take $380 Amazon bucks.
