Modern arcade controllers are pretty standardized. The 8 buttons on the right are your four face buttons and four shoulder buttons. That plus your 8-directional dpad means they work for just about any 2D game or 3D game that doesn't need analog sticks or a mouse. The left half of the 8 buttons is where the four face buttons go, in their standard positions more or less, but rotated slightly. Top two are the west and north buttons, bottom two are south and east buttons. This means PlayStation Cross and Xbox A are the same button, but in Nintendo layout that button would be the B button (gets even more confusing when you consider that PS3 can use Cross or Circle for confirm depending on the region). For the other four you have your triggers on the bottom and bumpers on the top, but right is before left. You may think that's backwards and confusing, but I think of it as putting the more important action first / on the stronger finger. You see the same with standard pad controllers vs the mouse. Left click on a mouse and right trigger on a controller both tend to be your primary fire. With that in mind you'd probably just treat it like a standard xinput controller for the bindings. I've pretty much just gotten into arcade controllers this year thanks to the new leverless (4 buttons replace the 4-switch stick) arcade controller trend + accompanying DIY scene. They're fun for fighting games, platformers, puzzle games, shmups, whatever they can work for pretty much. With the modern firmware options you can even emulate an analog stick if required for a game. I've been using them for as many games as I can lately. They even make arcade controllers with extra buttons now to play Smash Bros and other platform fighters (e.g. Rivals of Aether).
