NeoCDRX vs NeoRAGEx

NeoCDRX is a free homebrew emulator for Neo Geo CD and CDZ games on GameCube, Wii and Wii U through Virtual Wii. It supports region settings for USA, Europe and Japan, which provide different languages and can affect some game content. The listed processor cores are Z80 3.6 and M68000 3.3, and audio controls include a three-band equalizer for music and sound effects. Supported controllers include Wii Remote, Wii Remote Plus, Wii Remote with Nunchuk and GameCube controller. Media options include SD/SDHC, USB and DVD, plus GameCube options WKF and IDE-EXI V1. Virtual memory card saves can go to SD or USB, or to a physical GameCube memory card. Setup requires a Neo Geo CD/CDZ BIOS file named NeoCD.bin in NeoCDRX/bios. Each game goes in its own folder under NeoCDRX/games, with an mp3 subfolder for music. Wii and Wii U Virtual Wii installations are packaged for Homebrew Channel; using the Wii version requires a way to run unsigned code. The README describes the project as GPL open source, while GitHub lists LGPL-2.1.

NeoRAGEx 5.4e is a free Neo·Geo emulator for playing arcade games on Windows 10 and 11. Its portable edition can run without installation from a USB drive. Display options include CRT effects such as scanlines, curvature, bloom, and vignette, as well as pixel sharp mode. Fullscreen supports integer scaling and 4:3 or widescreen aspect ratios. Xbox, PlayStation, arcade stick, and generic controllers are supported, with automatic detection and button remapping. Save states, rewind, and screenshots are included. The listed minimum requirements are 64-bit Windows 10 or 11, a dual-core 2.0 GHz CPU, 2 GB RAM, and a DirectX 9-or-newer compatible GPU. NeoRAGEx does not include games or BIOS; it requires a neogeo.zip BIOS file and users’ own ROM files. The download page publishes SHA-256 and MD5 checksums for the installer, and the site links to setup, configuration, and troubleshooting guides. The project describes itself as independent and unaffiliated with or backed by SNK.
