After spending a few days trying basically every ti99 emulator out right now, I finally have the latest version of MAME64 running, loading and playing Hunt the Wumpus.

 

While I consider this a great victory, my problem now is that I can't find any way of changing the inputs for TI emulation to, say, a controller, or even different keyboard keys.

 

Everything I find on the web suggests that pressing TAB from inside the game should bring up a menu where I could change Input (General) and update inputs as needed. Presumably this would change inputs for the entire ti99_4a subsystem, and I'm fine with that, but the problem is that TAB doesn't bring up any kind of menu at all. Probably it's being rendered as a keystroke within the emulation core and not as a control key for MAME or something like that.

 

Either way, I very much need a way of remapping inputs for the platform in MAME. Anyone able to help with that?

 

I do have xpadder available, but I'm not having great luck with that (though it has worked fine everywhere other than in MAME and could conceivably be user error). Either way, if there's a way to natively assign inputs in MAME itself, rather than keyboard emulation in xpadder or joy2key or whatever, it would be preferable.

For some TI-related information on MAME, see www.ninerpedia.org

 

In your case, you must first switch to "Partial keyboard mode" by pressing ScrlLock. In "full keyboard mode", all keys are mapped to the emulated system, so there is no way to get to the MAME menu.

Thanks, that worked perfectly. The keyboard I was using didn't have a ScrlLock key so I had to dig one out, but now it's detecting the joysticks fine!

 

I did bookmark ninerpedia for future reference, as I'm sure it will come in handy. It doesn't look promising that I'll be able to map "BACK" and "QUIT" in any useful way (please correct me if I'm mistaken), but simply being able to use a controller and a fire button is a night and day improvement :)

You can use another key for the mode switch. Search for "Change MESS menu mode key" in Ninerpedia.

 

BACK is FCTN-9, on the PC keyboard it is Alt-9 or AltGr-9. QUIT is FCTN-=, on my keyboard AltGr-´ (two keys to the right of the 0). On a qwerty keyboard it should be =.

 

To define your controller keys, go into the MAME OSD menu, "Input (this machine)" and scroll down (or up) to the end of the list.
