SEGA VMU with RetroPie

[ignatius]

Hi, all.

I just got one of these units a few days ago. The Raspberry Pi encased in a SEGA VMU unit. I'm very new to RetroPie and all that. I'm curious, is it possible to "map" all of the keys (4 of them) to use the every key that is needed for a specific emulator. For example, the SNES emulator requires 8 keys. Is this possible? Maybe some sort of simultaneous key pressing? Again, I apologize. I'm a newb to this.

Thanks.

It's possible to expand those four buttons to ten inputs using an outside mapping solution like xboxdrv, but in practice playing any action-heavy game would be very difficult. Certain strategy games and RPGs that need the extra buttons might play well enough though.
