I bought a used X-arcade solo from someone on here recently. Honestly, as far as retail sticks go these are pretty decent, and a little better than the Streetfighter anniversary stick.
Like the stock controls: The KO happ concave with KO cherry switches, are pretty damn NICE for clones, and 100% better than what nuby put in the SFAC! Had they been convex i probably would have left some in.
The PCB, while its quality is questionable, it WORKS with converters such as for use on the PC! My modified SFAC won’t function at all with converters. Another plus for the X-Arcade.
The stock stick was identical to the SFAC’s though, definitely needed to be replaced. Anyhow once you modify it with Happ stick & buttons and correct the button layout, this stick is nice.
The case is good too, even though its smaller, it has all the properties of a larger case: Nice weight to it, does not jolt around during gameplay & stays seated, and enough room for comfortable hand placement. My only gripe is the way the stick is mounted higher than the buttons, but its not much of a problem and you usually forget about it once you start playing.
X-Arcade Solo: Underrated! I’m about to put a PSX PCB in mine soon.
