As some no doubt remember, Sonic & Knuckles provided back when it was released "lock on technology" which allowed it to connect to Sonic 2 and Sonic 3. Is this accounted for in the current generation consoles emulators, the Xbox 360 Arcade and Wii Virtual Console?

Waited 9 hours before I went and did some more digging and found my answer. Hopefully it's all right that I waited awhile before answering my own question. – The Jug Oct 17 '10 at 2:03
It's perfectly fine. One can read up more in this Meta question, but to summarize - waiting some time or immediately answering it are both acceptable practices. – Grace Note Oct 17 '10 at 3:02
All righty, thanks =) – The Jug Oct 18 '10 at 13:26

Did a little more digging and found the info needed. On the XBLA site for Sonic & Knuckles it says it does. Additionally found on, it says the Wii VC version keeps the lock on tech as well.

Actually, in the original Mega Drive/Genesis, you could put another non-Sonic game on top of Sonic & Knuckles and it would allow you to play ONE special stage for that cartridge. On the other hand, putting Sonic 1 would allow you to play countless special stages. It won't be the actual "lock-on" feature unless it allows locking on any cartridge. (but, still, allowing just Sonic 1 is good enough) – Denilson Sá Jun 24 '11 at 19:10

Yes, the lock on feature is present. Gametrailers mentions it specifcally in their review here.

Yes, the lock-on feature is completely present, allowing you to play Sonic 2 and Sonic 3 with knuckles, and includes the easteregg, which can be accessed trough a "fake" lock-on with the original Sonic the Hedgehog game leading you to the No Way? No Way! screen.
