Finally i got it run. 😅

 

Had to copy "TI-994A.ctg" and "/opt/ti99sim/roms/spchrom.bin" to "/opt/ti99sim/console/".

 

New Questions:

 

1. I have a picture, but its veeeery tiny.

 

Normally the option -f should lead to fullscreen, but wether this

 

  <system>
   <name>ti99</name>
   <fullname>TI-99/4A</fullname>
   <path>/media/usbstick/roms/ti99sim</path>
   <extension>.ctg</extension>
   <command>/opt/ti99sim/bin/ti99sim-sdl -f %ROM%</command>
   <platform>ti99</platform>
   <theme>ti99</theme>
   <directlaunch/>
 </system>

 

nor --fullscreen=1280x1024 leads to success...

 

 

  <system>
   <name>ti99</name>
   <fullname>TI-99/4A</fullname>
   <path>/media/usbstick/roms/ti99sim</path>
   <extension>.ctg</extension>
   <command>/opt/ti99sim/bin/ti99sim-sdl --fullscreen=1280x1024 %ROM%</command>
   <platform>ti99</platform>
   <theme>ti99</theme>
   <directlaunch/>
 </system>

 

The picture stays unchainged very small.

 

 

2. Is it possible to configure the joystick?

Where is the firebutton on the keyboard?

 

Cheers

Sid

Maybe this error has its cause in the new VC-Screenmode of the Raspberry Pi4.

Commenting "dtoverlay=vc4-fkms-v3d" in the config.txt out results in an errormessage.

 

Any Ideas how to solve that?

 

This is the part of the config.txt

 

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
dtoverlay=vc4-fkms-v3d
gpu_mem=512

This is how TI99sim looks on my Raspberry Pi 4 with RetroPie 4.5.2 installed.

In this small Window the games are unplayable.

Is there anyone who installed TI99sim successfully on the Raspberry Pi 4?

 

Cheers

PS.: This is my es_systems.cfg
