Step 5: Configure the `sys.txt` File – The Most Critical Step

This text file must be edited with Notepad++. Do not use WordPad. Create a new text document named sys.txt in the root Primo folder.

Paste the following verified configuration for IGO Primo 24 + Skin on 800x480 WinCE:

Performance & usability tweaks

Reduce map detail by loading only necessary regions.
Turn off 3D building rendering if present.
Use compressed voice files or text-to-speech if available.
Remove unused POI and speedcam files to reduce load.
Assign a simple home screen shortcut to the executable for faster launching.

Problem 5: No TTS (Text-to-Speech) voice

Cause: The skin is looking for TTS, but you lack voice_TTS files. Fix: Download a TTS voice pack (e.g., "Vocalizer TTS") and place the .dll and .zip files in the Primo/voice folder. In sys.txt, set [tts] enabled=1.

Resolution and scaling for 800×480

Target exact 800×480 assets for best sharpness; avoid upscaling.
Use 9-slice (or tiled) PNGs for stretchable backgrounds to accommodate different element sizes.
Touch targets: minimum 48×48 px recommended; larger for important controls.
Provide alternative layouts in layout/ for landscape vs. portrait and for DPI differences.

6.1 "Black Screen" or UI Freeze

Cause: Memory overflow. The 800x480 resolution renders high-bitmap assets which consume RAM. Solution:

Reduce the number of POI categories enabled.
Disable 3D buildings.
Modify sys.txt:
```

skip_eula=1
fov=60
