    Neo Geo SD Pro

    The Neo SD Pro is a wonderful device in my opinion. I like the completeness of being able to do the Neo CD. Admittedly for me the RAM slots are less important-but very nice to have. If you are tossed between the regular Neo SD and the Pro, Go Pro:-)

    NeoSD Pro

    Just get the original, not the pro. The ram slots are just impatience, and the CD support isn't the full monty.

    The best way to play the entire Neo Geo library (with Neo Geo CD support)!

    Posted by Tony Sakich on May 11th 2021

    After purchasing a 161-in-1 multicart for my Neo Geo AES, I realized that I'm missing a ton of the best Neo Geo games that are not on the cart (Windjammers and Ghostlop come to mind).

    I decided that the NeoSD Pro would be the best route and I'm definitely not disappointed as it plays every game perfectly, even supporting newer roms that have been released in the past year or two. The huge bonus of supporting a large percentage of the Neo Geo CD library is fantastic too as many CD versions have enhanced soundtracks.

    If you own a Neo Geo AES, this is a must have as it will give anyone access to every single Neo Geo game on original hardware.

    Does what it should.

    I've played through some AES and MVS stuff, no flaws there. NGCD support isn't perfect. You hear occasional loud blips and noises, but the load times are glitchy, but minimal. I recommend either way, hopefully some updates in the future are still possible.
