Still holding out hope for the original Crazy Otto. Scott Lawrence did a great job of the various revisions in Misfit Mame, but the true blue set that Steve Golson of GCC almost released a few years ago would be awesome.
Would also like to see the Donkey Kong, Donkey Kong Junior and Mario Bros 3-in-1 arcade game emulated. Did Nintendo encrypt this or something? I know we have all three separate games emulated, but I like the multi game cabs like the Ms. Pac-Man/Gallaga, Pac-Man 25th Anniversary and Space Invaders/Qix.
Laser Disc games too. Especially the ones Daphne do not have working like Goal to Go, and NFL Football from Midway.
More discrete logic games. Yes, I know about the Dice Emulator, but would like to see them in Mame with Mr. Do's artwork.
Donkey Kong Remix and Donkey Kong Junior Remix. The developer will not lose sales by releasing the roms. Hell, SELL them to us!! Most emulation people do not own a DK machine to run them on. If you DO own a DK machine, and you want this game, (and trust me, you do!!) buy the kit. It is AWESOME!! Sorry, but I do not have the space in my small condo for a DK machine to play the game.
Maze-Man and Barracuda. Pac-Man bootlegs. The former was mentioned in Ken Uston's book "Mastering Pac-Man". SIL did a pretty good interpretation of what he thought the game MIGHT look like, as only the maze was shown. He described the dots as hearts (already have a bootleg with this), energizers as beer mugs, and ghosts as "Richard Nixon Monsters". Obviously, we do not know if the attract mode was altered, and what the name of the ghosts were (if changed). Barracuda appeared in an issue of Electronic Games magazine. It was the Piranha graphics with the Hangly Man mazes. Again, no clue on if attract mode / monsters names were changed.
Keep the handhelds coming!!! What haven't the Mattel sports games (baseball, football, basketball hockey, soccer) been emulated yet?
