Are CD games region locked?

[SignOfZeta]

Or just skip Altered Beat entirely because its f*cking shit. The arcade version is only passable as it is. The PCE version tips the game over the edge into pure garbage land.

I'm surprised this thread has seen so much discussion.  The answer is NO.  Altered Beast shouldn't even factor into the equation.  Whether a CD system can run a Tennokoe Bank Hucard is a heck of a lot more important than its ability to play Altered Beast.

All one has to do is make sure their CD system can use any necessary system cards.

If someone wants to play the one terrible game that requires the 1.0 System Card (which was only released in Japan), they'll need to make sure their system can run a Japanese Hucard (i.e. play is on a PCE or on a U.S. deck with a converter or region mod).

If you want to play the twelve ACD games, you'll need to make sure your system can handle the Arcade Card Duo or Pro.
 
Same for GameExpress games.

Necro and Sunteam - what are these several games with incompatibilities you've hinted at?  If there are actually any others I'd really like to know.

There's just a few, not several.  Besides the aforementioned Altered Beast, the only ones I can think of are Bonanza Bros., Shadow of the Beast, and A. III.

Oh, okay.  Thanks.  Do these games require specific system cards?  Or do they not work in U.S. decks at all?

[thesteve]

they require certain system cards.

Was this released on PC-Engine...? 

[Edmond Dantes]

No.  It just kinda came up in the Image Fight II topic because X-Multiply was on a compilation with Image Fight I

[farankoshan]

Bonanza bros is on a genesis compilation for PS2. Yay for cheapness!
