[Connecting 2 IPACS]

Hi I am having an issue with connecting an IPAC to another IPAC (no need to ask why I have 2, it's because my control panel is way too wide for one) in my 4-Player Cab because when I plug each IPAC as a separate USB connections, it basically overlaps the other configuration when I load up Big Box and play a MAME game. 

Can someone tell me what exact cord or connection piece I need to connect one IPAC to the other one? I also want to do this to save myself another USB port. 

Or if anyone knows how I can make the computer recognize that I have 2 IPACs at the same time to configure, that would be awesome too!

Thanks Neil, appreciate all your help!  

So I changed the rompath.

Now I'm looking to add three lines to skip some unnecessary screens when loading a game:

skip_disclaimer 1
skip_gameinfo 1
skip_validitychecks 1

Where do I add these 3 lines? Under "CORE CONFIGURATION OPTIONS"?

I literally do not have that file lol.  I have everything else in your image.  I tried unhiding the folder and it's still not in there.

Ah I see!  This is great because I've been looking for this file to remove the splash screen whenever a game loads.  But how do I access this mame.ini file?! I don't see it anywhere in my MAME folder.  All I see is a "ini" folder but this has two additional folders "examples" and "presets" which I don't think is what I'm looking for.

  

[MAME pointing to wrong folder]

Hi, so I'm having an issue where everything was imported fine onto my LB/Big Box except the arcade games don't load (it just says "Initializing..." and then quickly goes back to Big Box screen) because I had moved the roms to my HDD. The ROMs are so huge that I needed to store them elsewhere so I moved them to my HDD while my MAME sits in my smaller SDD.

The problem is that now the filepaths for all my arcade games are messed up. I know this is the problem because I tested it by copying a game folder into the default roms folder in MAME and it now loads fine.

I know there's a bulk file path change for Launchbox for emulator-directing, but how about the reverse?

I really don't want to re-import everything because it took me nearly a day to import everything.

Is there an easy solution for this? Thanks in advance.
