Download from App Store

How to install on Android

Open Google Play (or your APK file from mi9.com) and install an NES emulator.
Copy legally obtained .nes ROM files into your Downloads folder.
Open the emulator → choose Load Game / Load Content → navigate to the ROM file.
Go to Settings > Input to map touch controls or pair a Bluetooth controller (PS4/PS5, Xbox, 8BitDo…).
Enable VSync (and Audio sync if available) for stable 60fps.
Create Save States before tough sections for convenience.

How to install on iOS

On the App Store, search for Delta (or RetroArch where available) and install.
Copy ROMs to your iPhone (via iCloud Drive, Files, or AirDrop) if permitted in your region.
Open the app → tap Import/+ to add ROMs → tap to play.
Pair a Bluetooth controller (iOS Settings > Bluetooth) and configure it in the app.

Availability on the App Store may vary by region and policy. If you can’t find the app, try a different region or wait for developer updates.

Optimization & controllers

Low latency: enable VSync, avoid heavy shaders; RetroArch’s Latency menu helps fine‑tune timing.
Display: use light scanline shaders for a retro look; skip heavy shaders on low‑end phones.
Saves: rotate multiple save‑state slots as a backup.
Controllers: PS4/PS5, Xbox, and 8BitDo work well; map once and save your profile.
ROM library: keep ROMs in a single folder so the app scans faster.

FAQ

Can low‑end phones handle NES?

Yes. NES is lightweight. Most budget and mid‑range phones run smoothly. Disable heavy shaders and keep VSync on for a steady 60fps.

How do I pair a controller?

Turn on Bluetooth → pair your controller → open the emulator to map buttons (Input/Controller). Popular options: PS4/PS5, Xbox, 8BitDo.

Should I use apps with built‑in ROM libraries?

Be cautious. Ensure the ROMs you use are permitted. The safest approach is using ROMs you legally own and dumped yourself.
