Namco Museum DS (E)(XenoPhobia) ROM

This game is just what you want for your old arcade fix. All the games are rendered well on the large screen of the 3DS XL, and the lower screen is often useful to quickly check various data while on the fly. An often overlooked game, Mappy, is in this compilation too. Every one of these games is worth the download.

(Note: I only briefly tested it on DeSmuMe, but it seemed to run well and looked good.)
