Nice to see you back you make great games!

Not sure if this utility would help you, but it does a good job with greyscale on the hp50G. http://www.hpcalc.org/details/6134

Thanks for your kind message!
OpenFire By Mario Lohajner (manjo) is really impressive. We don't know if an external lib is mandatory. Let's hope Mario see this thread and accept to share with us code sample and ideas.
