Battlezone looks fantastic. That wouldn't be too difficult to execute on a Vectrex I think... it's rather simple game. Fantastic! I look forward to the release of your version of the game.

You just lower the transparency of the layer in GIMP or some other photo manipulation software. This will color the vectors. If you want a border, then you erase everything that you don't want to see (playfield) in a separate file making sure that there is no background layer. When adding these files to configuration, the transparent layer will be the name of the game followed by a $ while the border will just be named after the game. Both will be placed in the data>packs folder.

I believe you will have to got to Layers>Transparency>Add Alpha Channel. This will make the background transparent. Then using the eraser tool, you change the opacity to your liking and go over the entire image, or whatever you want to be transparent.
Actually, this probably eliminates the need to use 2 files if you only make the playfield transparent. But I guess it might be useful to know how to create layers with overlays as well.

Thanks Tony, for your prompt answer. I've got a German GIMP and just set the Opacity in the "Layer, Channels, Paths," window to a lower value. Then I saved the graphic as PNG file and voilá it worked. It seems that GIMP automatically adds an alpha channel to the PNG file when saving (at least that's how I understand it).
Notes: - You have to use a pretty low opacity (<= 30%) to have the vectors shine bright through the overlay. - I didn't use the second file for the opaque colour.

I have an image but can't get the image to work. Anyone know how to make an overlay image ?

Has to be a PNG to begin with. Then have a transparent layer.

Think I also had to add the game to configuration.xml if its new to parajve
like this:
------------------------------------------------------------------------ <game id="VECFU" name="Vec Fu"> <roms system="DEFAULT" cartridge="data/roms/homebrew/VecFu.bin" /> <info category="HOMEBREW" author="MB" date="2010" /> <overlay tx="0.0" ty="0.02" sx="0.935" sy="0.935" passes="2" mipmap="true" path="data/packs/VecFu.png" /> <persistence enabled="true" history="20" /> <shininess normal="2.0" blurred="1.5" /> </game> ------------------------------------------------------------------------
I've used paint.net for the png.

I had the very same issue with adding an overlay.
The png I added definitely had an alpha channel that showed up fine with other viewers.
