NeoGeo CD Redux vs NeoRAGEx

NeoGeo CD Redux is an open-source NeoGeo CD emulator with build targets for Nintendo GameCube and Wii. The Wii target runs natively rather than requiring GameCube mode. It loads game media from SD cards and DVDs, with USB loading on Wii, plus FAT-formatted SD access through WKF and FAT-formatted hard-drive access through IDE-EXI. Wii controller options listed are Wii Remote, Nunchuck, Classic Controller, and GameCube controllers when the stated detection condition is met. Video output includes progressive modes and 480i, 480p, 576i, and 576p, with component-cable detection. MP3 playback from SD and DVD is documented. Save files can use SD storage or a memory card, while WKF and IDE-EXI write support was not included in the listed release. The project lists .bin/.cue, .img, and .iso images. It is free, and the latest changelog entry is unofficial version 0.1.52A.2 from July 18, 2013.

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.
