0.198 (I like to keep up to date even when a ROM set needs replacing)
Short answer: Launchbox CAN do that command line but it makes things trickier.
Long answer: To launch that particular line, I have to set LB to not use quotation marks, file extensions or paths. This WILL work but it breaks every other platform I use MAME to emulate (which is currently 11, not counting arcade ROM sets). The other option is to set up a new emulator listing for MAME specifically for TI in LB but that requires putting the ZIP files in MAME's roms directory, which, for various reasons, isn't ideal for me. I also just really want to know why this RPK isn't working for me. Among other reasons, it could indicate a problem with my setup that needs to be addressed.
