TNX again jorgeultra for yr help
1. button size : yr answer concern Number vertical of menu buttons. My question the size of the button itself small/big size.

2. 2. bmp -> jpg - try removing the ; from the screenshotfilename="\android_linked_root\captures\capture_%02d.jpg" line in your sys.txt file.
already done without success. That line works for Primo not for Nextgen. Here bellow the sys.txt commands for Primo

[interface]
capture_to_jpeg=1

[debug]
screenshotsavecameraini=0
screenshotfilename="\android_linked_root\captures\capture_%02d.jpg"

for some Primo (WinCE?) you may add
[folders]
app="\SDCard\iGO"
sdcardpath="\SDCard"
screenshot_dir="%app%/captures/"

3. I'll install the latest version skin later
