EverDrive GB / Re: GB/GBC Everdrive!

I have a multicart which actually lets you select a game from the multicart and then manages to reset the GBC (and not the cart), thus making it possible to play the games on the multicart properly colorized.  It obviously is possible--it just requires the correct hardware in the cart to send a signal over the reset line (which is available in the cart slot).  I don't see why an Everdrive wouldn't be able to take advantage of this--if it's designed to do so.

Edit: I looked up a pinout.  The reset pin on the Gameboy is the third from the end.  Looking at the circuit board image in the initial post shows that that pin is connected to something, so it's entirely possible that the Everdrive does do it.

It does depend on the ROM.  The GBC recognizes specific ROMs and colorizes them.  The problem is that in a normal multicart, the GBC sees the menu, not the ROM.  The user then runs the ROM from the menu, but at that point the GBC has already started up, and is past the point where it would do any automatic colorization.

In order to get proper colorization, the user would have to pick the ROM from the menu, the ROM would have to be loaded, then the hardware in the cart would have to reset the GBC (without also resetting the cart) so that the GBC starts up again seeing only the ROM and nothing else.  The GBC then sees the proper ROM *while starting up* and colorizes it.

Here's my own request: proper automatic colorization.

Some GB games (for instance, Metroid II) were automatically colorized in a GBC (or GBA) based on a list of palettes in the GBC BIOS.  The reason I bring this up is that multicarts with a menu--including the EMS 64MB--won't properly colorize the game.  Unless the game is in the right place in memory at the moment the system is reset, the automatic colorization will not happen.

Will the Everdrive run such games properly colorized?
