    I DONE MAKED GAMES.
    Thanks, Sik. I should have thought about it harder, I never used to swap out my 6-button controllers for any reason, so of course MODE worked. They're by far my favourite controller ever; practically touch-sensitive D-pads on all four of mine. Yeah, four. I don't want to ever end up with a bad controller during multitap Mega Bomberman sessions.

    The manuals for the 6 button controllers (and the Nomad) mentioned which games wouldn't work with them.

    Off the top of my head, I can remember Forgotten Worlds, Arch Rivals and Ms. Pac-Man.

    EDIT: Oh yeah, and Golden Axe II was also mentioned.

    Penguin Land on SMS won't work with the 6 Button and maybe not even the 3 button. Love the game though.

    I think the way Hivebrain made Template:Releases was done specifically for some functionality that we have set up now that could possibly be used for this, but I can't remember the name, it's a three-letter acronym starting with D

    After Burner 32X uses it to fire the gatling gun. I forget if AB2 has 6-button controller support at all.

    I think Star Wars 32X also uses it to change camera but I'll have to look it up.

    No, it was released way before the 6-pad was made (actually before even Street Fighter II, which is what the 6-pad was made for). That said, it does support the analog joystick.

    Aerobiz Supersonic uses the mode button ingame for showing a map or something ( I can't quite remember what it did, but I remember it did use it as a regular button)

    Out of curiosity, does the 6-button arcade power stick have analog features? I don't have one to test, and have next to no idea which controllers have analog support and which don't.

    No, the analog stick in fact doesn't even remotely resemble the MD controls.

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

    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!

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

    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...

    Star Wars Arcade lets you select the camera using it.

    A Pikmin fan engine - Pikifen (https://pikminfanon.com/Pikifen)
    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.

    ...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. :psyduck: AFTER ALMOST 20 YEARS.

    The reset button is the same way.
