NCDZPSP vs NeoRAGEx

NCDZPSP is a Neo-Geo emulator within NJEmu, a collection covering CPS1, CPS2 and NEOGEO (CD) emulators for PSP. It is listed for PSP, PlayStation Vita and PPSSPP, with Neo Geo CD support and save states. The latest listed release is version 2.3.5, published May 11, 2018, with an NCDZPSP2.3.5.zip download. That release records a game-list limit of 512, cheat support, multilingual support and command hotkeys. Its ROM set uses MAME 0.152, with some hack and bootleg sets added. The README maps O to OK, X to Cancel and SELECT+START to the emulator menu. The 2.3.x series is described as experimental; its notes warn that added features reduce free memory, some games may require cache files and some may fail to start. AdHoc online play does not apply to NCDZPSP, so netplay is unavailable. The project is GPL-3.0 licensed, and source builds require PSPSDK 0.11.2, MSYS and Makefile edits.

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.
