what is "PPSSPP style" ?

[mtsh1000]

hi, PPSSPP is a sony psp emulator and imo has best key binding functionality. It allows multiple keys bindings (many-to-many) without any restrictions and that makes possible to create multi button press macros which are very helpful in fighting games for example.

One button can be set multiple keys. Mame & supermodel are same. I think add marco like dojo version is better than it.
