Original gray unit. Not sure what mod is inside but I do know that it played my US and Japanese games. Light wear, including a couple missing bits on the spindle (does not affect performance). No hook-ups/controllers.
Do-Don-Pachi has a cracked case but is in great shape otherwise. Includes manual, registration card, back insert, and disc.
$75 + shipping takes both. Send zip code for quote, won't be more than $11.30.
