Pac-Man Connect & Play Debug

Imagine... the year is 2012, which is somehow ironic since Pac-Man's 35th birthday was three years later, which was when the PAL version of this Plug and Play was released. You go to the "Games" section of your nearest retailer and buy it to enjoy the many arcade classics.

If you happen to have no knowledge about its secrets, this article is here to go over a few through its debug mode, which is a secret in and of itself.

'''NOTE: Any information here is pertained to the NTSC copy. If you have any info on the PAL version, please add proof of it here.'''

Access Code
In order to access the debug menu, you need to hold both the A and B buttons during the copyright screen.

After this is done, you should see the colors red, green, and blue in that order, each flashing once for a second. This will confirm that you did the code correctly. You should then be redirected to the Factory Test Mode.

Factory Test Mode
This screen shows most of the system's info and values used during gameplay. You'll see the following once being taken here:
 * The build title ("BANDAI AMERICA NAMCO CLASSIC GAMES")
 * Sixteen IOA values possibly connected to controller inputs (0-15; ten values are presumably unused):
 * 10-13 are for Down, Right, Left, and Up
 * 3 and 5 are for the A and B buttons
 * Eight test pattern colors each shown to the right of and below the IOA, with fading gradually applied to the right one: White, Light Grey, Yellow, Cyan, Green, Magenta, Red, and Blue
 * The bLEN and bSUMB values
 * The build date and time
 * The region output (NTSC or PAL) and GPL16250 version

Test Mode: Checksum
This shows the SDRAM (synchronous dynamic random-access memory) code being swiftly read, checking for any errors during its repetitive pass cycles. You'll see the following once being taken here:
 * Four vertical strings of 62 4-digit values that, from top to bottom, change color depending on whether or not they were read:
 * Unread = Cyan
 * Read = Green
 * A pass and error counter, sharing the same traits of the aforementioned values (each value going from 0-F)
 * A note reading "This code reads from the SDRAM."

Test Game
For both of the modes listed above, each has a message reading "Hold A+B for 3 seconds to Continue." If said action is done, you'll be redirected to the New Rally-X game with an added volume meter, which is only there for you-know-what.

If both buttons are held again, you'll be taken back to the Checksum regardless of the amount of times that the code has been entered. Getting a GAME OVER will result in the game restarting and auto-crediting the player, meaning the only way to exit the game is to either hold A and B for three seconds again or turn off the console.

Turning off the console is also the only way to exit the debug menu.
