ER File – What is .er file and how to open it?

ER File Format

ER files are associated with Newer Super Mario Bros. Wii, a fan-made modification of the original Super Mario Bros. Wii game for the Wii console. They contain audio data used by the game, such as music, sound effects, and voices. ER files are typically packed into ARC archives, which are then loaded by the game when needed.

Technical Details

ER files use a custom audio format developed by the Newer Team. The format is similar to the WAV format, but with some additional features and optimizations for use in the game. ER files typically contain uncompressed PCM audio data, but they can also be compressed using the ADPCM algorithm to reduce their size. The format also supports loop points, which allow audio to be repeated seamlessly.

Opening ER Files using Emulators

To open ER audio files associated with the Newer Super Mario Bros. Wii (NSMBWii) romhack, you will require an emulator capable of playing modified Wii games. One such emulator is USB Loader GX, which allows you to load NSMBWii ISO files from an external USB drive. Once you have installed USB Loader GX, follow these steps to open ER files:

1. Extract the ER file from its archive (if necessary).
2. On your Wii console, launch USB Loader GX.
3. Insert the USB drive containing the NSMBWii ISO and ER file.
4. Navigate to the NSMBWii ISO and select “Load.”
5. Within the game, navigate to the “Options” menu and select “Advanced.”
6. In the Advanced Options, enable “Custom Audio Patch.”
7. Select the ER file from the USB drive.

By following these steps, you can successfully open ER audio files in NSMBWii using the USB Loader GX emulator.

Additional Methods for Opening ER Files

Alternatively, you can use a specialized tool called Wii Homebrew to open ER files. This requires a modded Wii console with the Homebrew Channel installed. Once you have Homebrew installed, you can install ER Player, which is specifically designed to open and play ER audio files. This method is a bit more technical but can provide additional functionality, such as the ability to adjust the volume and playback speed.

Newer Super Mario Bros. Wii Audio File Format

The .ER file extension is associated with the Newer Super Mario Bros. Wii Audio format, specifically used in the fan-made game “Newer Super Mario Bros. Wii” developed by Newer Team. It contains various audio assets such as music, sound effects, and voice clips employed within the game. To play or manipulate these audio files, specific software or tools designed to handle the .ER format may be required.

Technical Details

The .ER file format utilizes a custom audio encoding method developed by Newer Team. It is not a common or publicly accessible format, and detailed technical documentation is limited. However, enthusiasts and developers in the fan game community have created tools and plugins to support the playback and manipulation of .ER files. These tools allow for the extraction, conversion, and editing of audio assets within the game, enabling modifications and enhancements to the game’s audio experience.
