Says its a PAL checker on the box, it seems to have a 220-240V psu but haven't had time to test it yet, however I will do so very soon.

LMK if anyone is interested.

errr it checks addresses.

Stolen from another forum:

"This circuit conducts a simple check for illegal accesses on each Dreamcast bus.
If the result of the check is an error, the circuit lights an LED. The circuit can also output an interrupt if an error is generated.
This circuit checks for the following:
• Accesses to the CS2 and CS6 areas (unused)
• Accesses to the GD-ROM reserved area and writes to the boot ROM area
• Accesses to the flash image area, accesses to the AICA image area, illegal G2 commands (the entire G2 area)
• Accesses to the modem area, accesses to the G2 external area (2MB and 32MB are separate)
• Accesses to the texture memory reserved area. A total of 20 errors can be indicated."

I tested it today. It's fully working the LEDs light up and change according to whats the console is doing.

It has a Japanese shell, but the PSU is 220-240v and it only plays PAL games (I tested Jap and US, and other discs).
However if anyone wants it I can chuck in a free 110v PSU which will just slot into the console.
