Just do this. Relist the sucker, avoid keywords like 39 in 1, Multicade or mame in the title.
Best to give it a title like "(Insert game name) with upgrade kit for extra games".
Then make the entire contents of your auction an IMAGE. One image, all your pictures, all your text, everything in the image. The automatic search robots will never pick it up, but your customers will be able to read it just fine.
DO NOT make it a featured auction.
