Analog stick? I thought it was an analog controller, specifically called the XE-1AP and made by Dempa.

[Sik]

You know what I mean =P Technically the only times I've seen it referred officially is as "analog joystick". And I'm starting to think it's actually several third party joysticks that happen to share the same protocol.

Playing with my Everdrive tonight and messing with the MODE button, I stumbled into a game that uses it.

Batman: Forever. Hold the mode button while moving to moonwalk backwards, and hitting punch / kick while doing this gives you backwards-style punches and kicks!

[Chilly Willy]

Wolf32X uses it to bring up the auto-map. 32xrick uses it (with X, Y, and Z) to activate the cheats.

Here's how Forgotten Worlds reads its controllers:

maybe someone can figure out what Sega did wrong here?

[Sik]

It isn't doing any wait between the write to the DATA port and reading back from it. It isn't giving time to the joypad to react. Guess the 3-pad is much faster than Sega thought, but the 6-pad isn't anywhere that fast...

DOOM uses it. Although it's not written in the manual, you can hold it and press A, B, C, X, Y, Z, or Start to select any one of the seven weapons in the game (assuming of course the player has the weapon of choice).

That's about all I have for you though.

Star Wars Arcade lets you select the camera using it.

[Espyo]

I know that in Beyond Oasis/Story of Thor, if you hold MODE and press B, you switch between your last selected weapon and the dagger. It's also used for a recently discovered cheat code.

[MooMoo]

...and today was the day I learnt that Mode can be used in game and wasnt just something you held while turning the Mega Drive on. AFTER ALMOST 20 YEARS.

The reset button is the same way.

[MooMoo]

What games does it do in-game actions for?

MY WHOLE LIFE IS A LIE. ;__;

The first X-men game requires you to reset the console to complete a level.

[ChEeZeBaLL]

You have to hold the mode button for a good 10-20 seconds when you turn the console on when playing King Of The Monsters with a 6 button controller or else the controller won't work.

As others have said, certain games weren't compatible with 6 button controllers and holding the mode button when turning the console on disabled the X Y and Z buttons.

[SpeedStarTMQ]

This is interesting, I just got my 6 buttoned controller through the post and had no clue what mode did. Now I know! When you lot are saying to hold it when booting the system, what the heck does that do!? :S

[MooMoo]

I cant even remember what games you need to hold mode on...I think maybe MK1 was one. I don't know exactly how it works, I assume it maps the buttons out correctly somehow, else otherwise they go all screwy and XYZ just don't work. :T I'm curious to find out, since you're essentially teaching the MD to use 3 new buttons I guess.
