NCDZPSP vs NeoGeo CD Redux

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.

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.
