Emulator Choice (PC / Mac / Mobile) Walkthrough, Secrets & Cheat Codes

PC / Mac / Mobile · 2026 · Open-source community
Quick Answer

Use RetroArch if you want one app for everything; use a dedicated emulator (Mesen, Snes9x, mGBA, DuckStation, PCSX2) if you want the best accuracy for a single system. The real decision is 'one app vs. best-in-class per console' — not brand names.

1Game Basics

Approach ARetroArch (one app, all systems)
Approach BDedicated emulators (best accuracy)
Price100% free
SkillBeginner to intermediate

RetroArch unifies many 'cores' behind one interface; dedicated emulators focus on doing one console perfectly. Both are legal and free.

2Core Gameplay

Accuracy matters most for timing-heavy games. A highly accurate emulator reproduces frame-perfect behavior; a fast-but-loose one may desync audio or break a trick. Pick accuracy for puzzle/platformers, speed for casual replay.

3Step-by-Step Walkthrough

  1. NES/Famicom: Mesen (most accurate) or puNES.
  2. SNES: Snes9x (easy) or bsnes (cycle-accurate).
  3. GBA: mGBA — the clear winner.
  4. PS1: DuckStation for ease, Mednafen for accuracy.
  5. PS2: PCSX2 (still the only serious option).
  6. Prefer one launcher? RetroArch bundles cores for all of the above.

4Hidden Secrets & Easter Eggs

RetroArch's 'shader' library can make pixels look like a 1990s TV or a crisp modern screen — a hidden rabbit hole players enjoy for hours. mGBA has a built-in cheat-search that finds values live.

5Cheats & Codes

No codes needed: RetroArch's rewind and save-state buttons replace most classic cheat devices. Original in-game passwords still function inside the emulated game.

6Player Reviews & Tips

Veteran users recommend starting with RetroArch to learn the interface, then switching a favorite system to its dedicated emulator for the cleanest experience. Either way, own your games.
