Great it is solved. What controller/handheld are you using?

 

Another change that could be added, is to use one of the Start/Select buttons as a "selector" to switch between different key mappins. E.g. pressing Select once is used for a mapping that fits for TI carts, pressing twice for Atari carts, etc.

 

 

I am using the 8bitdo SN30.

The switching sounds useful.

Are you sure to use the modified version? I don't remember if make install is using the correct RetroPie path.

 

Compile the modified version with your mapped buttons, then replace manually the binary in /opt/retropie/emulators/ti99sim to be sure.

 

My steps were:

 

sudo su -
cd /home/pi/ti99sim-0.16.0/
mv /home/pi/RetroPie/roms/ti994a-sdl.cpp src/sdl/.       <---- I'm editing the ti994a-sdl.cpp file from PC, then moving it in this Samba share. Change this step if you're editing using vi
make
cp bin/ti99sim-sdl /opt/retropie/emulators/ti99sim

 

Check the timestamp of the ti99sim file to be sure that you are using the updated file.

 

 

If you are using the correct file, next step is to check the mapping events for your controller, using the xboxdrv tool. Have a look at this link:

Note that the new version of ti99sim is using SDL 2.0, so here are some docs on joy events:

Hope it helps.

 

 

 

 

 

 

Thanks, I forgot to move the new ti88sim-sdl file to the /opt.... folder

I appreciate the follow up!

Thanks for the mod, been trying to get this for a while.  I have a different controller and am trying to remap the buttons and keypresses.

 

I have downloaded the full souce of ti99sim.16, but can't get the buttons to register a different keypress than what is in your ti99sim file.

 

I look at what you have done and change the case number, the order the case#s are in and the VK_#, the run make and make install (with and without sudo) from the ~/ti99-simsdl.16 directory.  The output list the text ti994a-sdl.cpp then returns to the command prompt.

 

I restart emulatiostaion and the pi, but the buttons don't chance.

 

Should I change something is in the file?

I can poke around the command line, modify some config files and try to reverse engineering scripts I find on the internet to suit my purpose, but am having trouble with this one.

 

Would you be able to give me a little more guidance as to how to change the buttons on a controller to issue different keypresses to the ti99.16 emulator?

 

Thanks
