MAMEWorld Forums - EmuChat - Run and Gun 2 throws errors and runs far slower from command line than GUI

Hi everyone, I hope I'm putting this in the right place - I'm still waiting for my account to be verified so I can post this to mametesters.

Running rungun2 from the command line with "mame64 rungun2" spits out a ton of errors when you get to gameplay that look like this:

Code:

GXT4: unknown protection command 125c (PC=209948)
GXT4: unknown protection command 3a56 (PC=209948)
GXT4: unknown protection command 1b55 (PC=209948)
GXT4: unknown protection command 3357 (PC=209948)

I saw this reported in the bug tracker, and the comments there made it sound like it shouldn't be that big of a deal, BUT when you run the game from the built-in GUI, it runs WAY faster than from the command line. When I run it from the GUI, I get 160% speed during gameplay (leaving plenty of headroom for 60fps all the time), and when I run it from the command line, I only wind up with about 70% speed (making the game unplayable).

Does anyone know what's going on with this or how to disable the error messages from showing up? I can't just "run it from the GUI" because I'm using a different front-end for my games and obviously they get run from the command line.

Any help is most appreciated! Thanks!
