レトロNESエミュレータ

[Experience 8-bit masterpieces on your smartphone]

This app is an emulator for the NES/Famicom, a home game console that took the world by storm in the 1980s.

You can easily recreate the gaming experience of that era on your smartphone by loading your existing .nes format ROM files.

━━━━━━━━━━━━━━━━━━━━
■ Immediate operation check after installation
━━━━━━━━━━━━━━━━━━━━
This app includes a sample ROM (test_rom.nes) created by the developer for operation checks.

(This is a self-made ROM with clean copyright, so you can use it with confidence.)

Simply launch the app, and the sample ROM will be automatically loaded.

The following "controller test screen" will be displayed on the screen.

HELLO NES EMULATOR
CONTROLLER TEST

A B SL ST UP DN LT RT

------------

The eight items on the screen correspond to the respective buttons.

• A / B: A / B buttons

• SL / ST: SELECT / START buttons

• UP / DN: Up / Down on the directional pad

• LT / RT: Left / Right on the directional pad

When you press a button, the indicator at the corresponding position changes from
"- (not input)" to "■ (input)".

This allows you to see the following at a glance:

● Is the screen rendering working correctly?

● Does it run smoothly on your device?

● Do all touch buttons respond correctly?

● Are all directions on the directional pad recognized correctly?

● Do simultaneous button presses (e.g., A + Right, B + Up, etc.) work correctly?

For those who want to "try it out before purchasing" or "check compatibility with their device,"
you can verify operation immediately after installation without needing to prepare additional ROMs.

■ Main Features

You can immediately launch ROM files saved on your device by selecting the file.

● Includes a sample ROM for testing custom key operations

You can check the operation of all buttons immediately after installation without needing to download anything additional.

● Touch operation optimized for the screen

The directional pad, A/B buttons, and SELECT/START buttons are placed on the screen.

Button size and layout have been adjusted for comfortable one-handed gameplay.

● Wide Mapper Support

Supports major mappers such as NROM / MMC1 / UxROM / CNROM / MMC3 / AxROM / Mapper 87, etc.

Many software titles will work.

● Persistent Save Data Storage

Save data is stored in the device's persistent storage so that it is not lost even when the app is updated.

resulting in smooth operation.
