Mame, arcade platform/system dont match in rocketlauncher

[chito]

When i added my mame roms to LaunchBox, I selected "arcade" from the list of platforms and RocketLauncher as my emulator. it scraped the metadata fine.

Then in RocketLauncher under the System list "arcade" shows up. When i tired to select a default emulator, the list was empty and no matter what i did it was always empty. After a lot of time and trying different things i realised that RocketLauncher  doesnt know that mame is emulator for the "arcade" platform in LaunchBox.

i ended up renaming the platform in LaunchBox from "arcade" to "mame" and then mame showed up in RocketLauncher and i was able to select mame as the default emulator. This feels like such a crap way to fix this issue. is there a better fix, has anyone else had this happen?
