Hi all, thank you for your responses to my questions about the paint program. I have two more questions I would like to ask with regards to the CMM2. Firstly, is there an extension for a PC paint program like libresprite or gimp that would allow me to draw using the 12 bit rgba scheme that is on the CMM2? And secondly, how do sprites work on the CMM2? Is there a good resource for that I could consult? Thank you. |

The CMM2 user manual has detailed explanation about sprites and other commands and functions. https://geoffg.net/Downloads/Maximite/Colour_Maximite_2_User_Manual.pdf The CMM2 graphics manual expands this material. 2021-04-05_114624_Graphics Programming on the CMM2-v3f.pdf Usually I edit my images on Gimp and export them as PNG selecting the appropriate pixel format  |

Earlier I posted questions about my paint program on my cmm2 (gen2). I hope, the questions are no to silly or annoying. this is a link to youtube with 4 of my movies that show the screen memory error. https://www.youtube.com/@heinrichhubbert8474 or to the movies... this is the basic sourcecode 2026-04-27_215913_hg.bas.zip is it my bug or what is the reason for the memory/screen mistakes? perhaps you or disco4now could read this. many thanks.

I experienced similar Reported here But I found that a different resolution was better for my needs and the flicker didn't occur. |

That would be good. I previously ran the code and can see the artifacts he is seeing. I did not really get anywhere to resolve it. There is a memory leak with CURSOR ON/OFF that is fixed in latest CMM2 betas. I was suspicious that the GUI controls and the drawing code where both trying to update the cursor.
