Subject: Turbo Outrun Megatech


After talking with ANY and a few other people I've decided to change the 
rom being used by the MegaTech version of Turbo Outrun.

In all other cases the roms in Megatech carts match the Genesis roms 
(and have the same Sega part numbers where we know them) 

In the case of the Turbo Outrun dump, 1 byte differed.  This seems 
highly unlikely, and the Megadrive dump has been verifeid by multiple 
sources.  ANY suspects the mask rom in his cart has developed a fault.

I've left documentation of the old dump in the file, just in case 
another cart comes along which is the same as the one dumped (as long as 
it isn't the same cart ;-) but chances are it's just a bad rom.
