Configuring TI 99/4A in Launchbox

[Flickumbicus]

If I run the command line version of MAME without any parameters, and navigate through the menu that comes up, I can load and run TI 99 games just fine.

If I try to use Launchbox to run them, it just opens a black screen then closes right away.

I have added MAME as an emulator, and I have added TI 99 as an associated platform, put "ti99_4a -cart" into the Default Command Line Parameters, and checked it as Default Emulator.

Any ideas? I can't see what MAME is doing under the hood when I use its built in menu to launch games, so I can't replicate it. I'm guessing something is wrong with the Default Command Line parameter line.

The command line looks fine.  For your MAME emulator settings, do you have these 2 check boxes checked?

[Flickumbicus]

No, I don't. I do have "attempt to hide console window..." checked, though.

[JoeViking245]

Then "Attempt to hide..." doesn't matter.  Try checking those boxes and see if it works.

Well, that fixed it. Thanks! But, I do wonder if that's going to mess up other platforms I have running with it. Maybe I can add the Mame executable a 2nd time and configure it this way just for TI99?

[JoeViking245]

No. It won't mess up any of the other softlists nor MAME machines (Arcade Platform).  Assuming MAME is setup properly with the rom paths in mame.ini.

The only exception I've come across for this is neocd (neocdz).  I couldn't get it to launch with or without the checkbox's checked.  But using the exact same command line, it would load if I put that in the games' custom command line.  (I didn't spend a whole lot of time on it, so it's quite possible that it was operator error, combined with a lack of patience).

Good to know. Thanks again for the assist! I really appreciate the help!
