This should be usable on MTM2, and my original post about it disappeared with the forums. It's available in the downloads section of
www.4x4evolution.com, oddly enough I used a fax viewer as the basis for this. While the color accuracy isn't as good as slice60, it does offer much more in terms of flexibility.
What it does:
-Slices tiles into multiple sizes (64, 128, 256)
-Can output to multiple formats (RAW/ACT, BMP, TIF, jpg, GIF)
-Outputs in 8 or 24-bit color
-Applies needed padding (detail area is 60,120,240)
