I have a Doctor 16M cart and have successfully used the GBPACK.V13 menu to make multi-ROMs.  These do run fine on an original DMG, but when used in an AGB or CGB (I have only tested in an AGB), they load in CGB mode.  This is generally a good thing, as it allows you to use Color games / software.  However, it also means that when I am using original Game Boy ROMs in my AGB I lose the ability to change palettes (I especially like the look of Nitro2k01's Shitwave with the various palettes).  I can still do this by flashing a single ROM to the cart, but would also like to have this ability when using a menu.  Does anyone know of a suitable multi-ROM menu which runs in Game Boy mode (i.e., does not have CGB support)?

I might also consider making a GBC compatible version of Shitwave (that is, including the graphics) but it was all meant to be a half joke originally.

Thanks.  I'd had a look around Subport previously, but all the menus there seemed to have CGB support (not that I tried them exhaustively).  The source code from the other site was potentially promising;  I was thinking I could compile it as a DMG-only ROM.  I was then struck with the idea to change byte 0143h of the header of GBPACK.V13 to disable CGB mode, and then recalculate the header checksum.  This worked successfully.

That being said, I would still very much enjoy a Color version of Shitwave, especially if it has a Color randomize option.
