Released a very early version of the NeoCD RX emulator , the Neo Geo CD/Neo Geo CDZ emulator, running on Wii U GameCube , Wii and Virtual Wii consoles .

A fork of the NeoGeo CD Redux (Infact) emulator and Wii port of the NEO-CD REDUX emulator for the GameCube , originally coded by developer Softdev .

The program also includes pieces from other less known emulators ( NeoCD-Wii and NeoCD Redux Unofficial ). By the way NEO-CD REDUX was itself based on the NeoCD/SDL 0.3.1 emulator (Foster) and NeoGeo CDZ (NJ), which are ports of the original NeoCD emulator (Fabrice Martinez).

Installation and use

To use the NeoCD-RX emulator on the Wii/Wii U Virtual Wii, extract the folders (directories) appsand NeoCDRX from the archive .zipwithin the SD or USB device.

Comes pre-packaged in the Homebrew Channel format, which is also compatible with official shippers. Then, you need to place your game files and music tracks into individually named folders within the \NeoCDRX\games.

For the GameCube port, you only need to deal with theNeoCDRX included folder.

Finally, you need to obtain an appropriate BIOS dump of the Neo Geo CD/CDZ console. Copy the file inside the directory \NeoCDRX\biosand rename it to NeoCD.bin. The emulator only works with the following files:

Neo Geo CDZ BIOS (NeoCD.bin)
Size: 524.288 bytes
CRC32: DF9DE490
MD5: F39572AF7584CB5B3F70AE8CC848ABA2
SHA-1: 7BB26D1E5D1E930515219CB18BCDE5B7B23E2EDA

Neo Geo CDZ BIOS (NeoCD.bin)
Size: 524.288 bytes
CRC32: 33697892
MD5: 11526D58D4C524DAEF7D5D677DC6B004
SHA-1: B0F1C4FA8D4492A04431805F6537138B842B549F

At the end, you can proceed with running the emulator, you can also install the NeoCD-RX Forwarder Channel on the Wii or vWii System Menu, or the special NeoCD-RX Channel for Wii U, which reads the necessary configuration and files from the device folder , be it SD or USB.\NeoCDRX

Configuration

To configure NeoCD-RX , press in the “Settings” box. A screen will appear where you can configure the items “Region”, “Save Device” and “FX / Music Equalizer”.

“Region” allows you to change the region of the emulated console, access other languages and, in some cases, edit or uncensor game content (fatalities, blood, difficulties, lives, title screens, etc.) . Reload the game (do not reset) for the settings to take effect.
“Save Device” offers two options, use “SD/USB” to save the SRAM memory (a sort of virtual memory card implemented inside the real Neo Geo CD console) directly to the multimedia drive, or use “MEM Card” for saving to a physical GameCube memory card, like you would on a real Neo Geo AES, for taking your progress to another console, or just for the nostalgia factor.
“FX / Music Equalizer” allows you to turn up the volume on audio FX or MP3 tracks, or increase the gain in the low / mid / high frequencies to your liking.

Preparation of the games

For each game disc, you need to create a subdirectory within the included ” \NeoCDRX\games ” with any name you like, and copy all game data files there. Inside this folder, create another subdirectory called ” mp3 “, where you need to copy your music tracks. IMPORTANT : even if you will not use the music, the folder is necessary.

Music tracks must be encoded from the original CD’s 44.1 kHz Red Book WAV standard, to MP3 format (minimum 128 kbps or higher), named exactly “TrackXX.mp3 “ where XX is a number always starting with 02, since the data track is always 01. Free audio ripping software for CDs is readily available.

Examples and images are inside the NeoCDRX_manual.pdf https://github.com/niuus/NeoCDRX/blob/main/NeoCDRX_manual.pdf

After this, you are more than ready to start playing. Each game folder created will be treated by the emulator as a complete CD.

Changelog

First outing.
SDHC and USB support fully functional. You shouldn’t see the emulator complaining about BIOS not found again, if you already have the correct file in the correct folder, especially on USB devices.
Saving Neo Geo virtual memory card is fixed again. Use SD/USB or GameCube memory card, the latter also works on Wii (backward compatible unit).
Fixed GameCube controller analog stick support. It didn’t work on the Wii, only when used on a GameCube console.
Internal menus reorganized for future expansions.
Some order.
