I can’t seem to find any info on these (can’t find it on hori’s JP site) - besides assuming stock hori stick and craptacular buttons. The one thing that intrigues me is the size of the case. If it’s easily moddable, that’d be pretty sweet.
The word is that there are certain requirements both Sony and Microsoft mandate for their licensed software and accessory developers.
MS has the (infamous) requirement for multi-colored buttons on all the third party 360 controllers.
Both companies supposely have requirements for 8-button faceplates on the joysticks for not only macro (aka “easier super move execution”) reasons for less experienced gamers but also to make the joystick controllers more versatile and usable across games besides fighters.
There are actually a few fighters that DO use 8 buttons (Marvel Vs Capcom 3) and quite a few earlier generation other genre games on consoles like the Sega Saturn that require an 8-button layout. It’s not as typical for games today but it does pop up occasionally.
I remember the PS1 Hori Compact Joystick was one of my first retail console sticks back then, from what i remember, it makes a great novelty stick or casual playing (i used it for shmups more than anything else)
