@ditch123 I know this is an old topic. But it looks like a bunch of know it alls replied to this message, and didn't even remotely answer the guys question. To get run and gun to play and passed the load screen you have to hit f2 and f3 at the same time. You most likely never got this game to work. I hope you now will.

@BuZz Thank you. I just realized I could configure this within the input configuration of mame4all. I was working too late last night I think.

@Sailing_Nut

Arcade ROMS are confusing at first and there are a LOT of questions. The Admins have put together a lot of documentation to help people out and unfortunately, there are a lot of people that just expect the admins to do everything for them, Unfortunately, the Admins don't get paid and the expectation to have everything handed to people is getting really common these days.

Just as an FYI, The extra instructions are located under the individual emulators. For instance, MAME and FBA have the managing roms link. Other emulators have instructions for specific configs and such.

You can also always Google "Retropie MAME" or "Retropie N64" to get to the direct links as well.

@Haemogoblin said in RetroPie is v4.1 RPI2b advice:

I'm just looking in to how to direct Retropie to use one single rom directory for both emulators.

The /home/pi/RetroPie/roms/arcade/ directory was made for this use case. And then you have to define what arcade emulator to use when launching a game in runcommand menu (you just need to set this once).

edit: this post seems to have some useful info for you: https://retropie.org.uk/forum/topic/5674/solved-rom-version-numbers-to-match-emulators

@hepc as far as I know, you need to use ESC from a keyboard. Get a RPI 3 ;-)

@cyrus Never mind, you have to press TAB in game and then you can configure the buttons
