 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Hello everyone I completed the game intro and main menu implementation. The next steps are to implement stages 07 and 8. https://www.youtube.com/watch?v=xB08OaIKxmU |

@LeoNicolas, Is the code here https://github.com/leonicolas/knightmare-cmm2 out of date ? I ask because if I look at init_menu() it makes a series of calls to print_centralized() which will ultimately blit the text glyphs to PAGE 1 ... ... but I can't find any code that then copies PAGE 1 to PAGE 0 so (at least in MMB4L) that text will never be displayed. Doesn't seem to work as it currently is on either MMB4W or MMB4L ??? Best wishes, Tom Edited 2024-07-17 03:57 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

At the start of "init.inc", Leo uses "mode 3,12". Page 1 sits on top of page 0, no? Visit Vegipete's *Mite Library for cool programs. |

Yes, I use mode 3,12 and both pages (0 and 1) for background and text. It works on MMB4W. I haven't tried on the real CMM2 or the Pico yet. Yes, the source code is up to date in the repo. I needed to stop the development for a couple of months. I'm near to complete the level 7 development. I'm planing to come back to the game at the end of August. Unfortunately some life problems are holding me now Thank you for reviving this thread |

Thank you, I was unaware of this "wrinkle" and had just commented out the ", 12" whilst I was getting other things working. If a version on the PicoMiteVGA is possible (maybe even the Game*Mite) then your display model will require considerable rework as they don't have the same PAGE model as the CMM2/MMB4W being restricted to the display (N) a frame buffer (F) and a layer (L).

Tom See the chapter on "12-bit mode graphics" in the document "Graphics Programming on the CMM2-v3d.pdf" included in the CMM2 firmware download zip for info on 12-bit mode. The layer buffer on the PicoMiteVGA is an attempt in software to mimic what the CMM2 does using the capabilities of the STM32H7 H/W Edited 2024-07-17 21:44 by matherp |

If necessary I can combine both layers in one framebuffer and blit it to the screen Edited 2024-07-17 22:55 by LeoNicolas |

Thank you Peter, I've managed to implement a semblance of that, though (if I can be bothered - which may depend on whether semi-transparent is a feature actually in use) I may have to mess with the transparency as currently for simplicity I have 256 alpha levels rather than the 16 used by the CMM2 in this mode.

Hi @LeoNicolas, The file "music.inc" includes a number of calls to PLAY MODFILE with an interrupt set at line 16000 ... except there is no line/label 16000 ? Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 8682 |
It isn't an interrupt, it is the modfile playback sample rate |

... thank you. Thus identifying another missing feature in MMB4L and also explaining a later error about mismatched sample rates that occurred with MMB4W after I commented it out. D'Oh! Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

You must also bear in mind that the Picomite has less memory than the CMM2, the use of FrameBuffer(F) AND Layer(L) is very memory-intensive. Cheers Martin 'no comment |
