Haha, that's funny, as I DO NEED the CPS2 kick harness...
As for the menu, move left to go left one game, move right to go right one game, move up to go right 10 games, move down to go left 10 games.
Last game rolls around to the first in the list, and first game rolls to the last in the list.
What about a filter color scheme for each type of game, maybe just a big round colored dot somewhere on the screen . RED = Fighting, BLUE = SHUMP, so on.
So if you sort by color, the menu will have all red games in a row from a to z, and then all blue games in a row from a to z, and so on.
Select one or more of the top lever filters:
All Games
Sort by Letter
Sort by Color
Sort by Folder (by Year)
Then once you are in that menu, select your letter, color, folder.
Or if you selected more than one filter, just go straight to that list. Example, all games that start with "M" and color of blue in the "1997" folder.
I like the original NEO*GEO logo on start up
