JP Bare Knuckle 3 compatibility?

[Jason Allen]

Does it work on a US Genesis without any types of converters?

[David J.]

You'll need a Game Genie. Here's a code:

AABT-AA5L
DJBT-AADN
RYDA-A608
AJDA-AAHA

You will need a regional lock-out converter cart like the Mega Key to play it on a non-JP Mega Drive console.

I play my BK3 on a modified EU Mega Drive with a Game Genie, no codes.
