Abstract New Super Mario Bros. (2006) for the Nintendo DS remains a landmark 2D platformer. As original hardware becomes scarce, PC-based emulation offers a preservation and access pathway. This paper evaluates the technical requirements, emulator accuracy, control schemes, and legal considerations for running this title on modern personal computers. It concludes that high-fidelity emulation is readily achievable on commodity hardware, though input mapping and touch-screen emulation present unique UX challenges. 1. Introduction The Nintendo DS’s dual screens, stylus input, and microphone pose non-trivial emulation hurdles. New Super Mario Bros. (NSMB) uses these features moderately: touch for minigames and world map cannons, microphone for blowing away specific obstacles. A successful PC emulation must balance cycle-accurate CPU/GPU emulation with peripheral mapping. 2. Emulator Selection & Performance | Emulator | Accuracy | Performance on NSMB | Key Feature | |----------|----------|---------------------|--------------| | DeSmuME | High | Full speed on 2+ GHz CPUs | Save states, HD rendering | | MelonDS | Very High | Near-perfect | Local wireless, JIT recompiler | | NO$GBA | Medium | Full speed | Lightweight, older |
