Found this video last night, thought I would post it: The history of Lemmings... I was mildy addicted to this game back in the days of MS-DOS 6!  Watching this video about it, almost makes me want to find a port that will run in DOS-BOX on more modern hardware.  But I have too many other things to get done. Perhaps someone could port it to the CMM2?  Edited 2025-05-19 11:47 by Grogster Smoke makes things work. When the smoke gets out, it stops! |

As a demo for "Simple_Sprite_Draw", a program to develop sprites for animation, there was a single lemming walking. But...yah.. it needs a game. For PicoMiteVGA.

Hey, man......I was just joking, but bloody hell!  Perhaps with some more MMBASIC, we could have a CMM2 Lemmings. I'd play it. For HOURS. Smoke makes things work. When the smoke gets out, it stops! |

Oh - That would be amazing. One of the best games on the Amiga. |

On the pico 2040 VGA you can animate 12 lemmings in 2ms (the large 13x20 sprites). When you have 20-30 of these larger ones on screen if is really crowded. But a simple game would be possible while keeping the speed at 100ms (typical lemmings walk speed). That would be roughly 5-6 ms (just animating the sprites). A lot of game loop will be in the individual control of each lemming. -find the floor and act to it (climb hill, fall down) -detect obstacles like walls, or lemmings that stop you -select the right sprite with the movement. And then we lose roughly 25% speed in music + sfx. I have no idea how much mouse control would require yet. But I intend to find out. But I think it should be do-able. With 30 max larger lemmings. A game with 100 small ones is another league. That would definitely require a 2350 or CMM2. Question is... is this simple 30 lemmings game worth developing. If everyone would be disappointed, and only settles for the 100 lemmings game, no one will be happy. Volhout PicomiteVGA PETSCII ROBOTS |

I would go directly to the CMM2 - it has the graphics ability. Well, much MORE graphics ability then the PM, although, I have not played with the new 2350 chip, so I don't know it's capabilities there. But the CMM2 was my original thought. I was just joking about this though. It would only be worth doing, if someone had the spare time and wanted a challenge. Oh, I know that already.  Smoke makes things work.

You need the power of the CMM2 to have some fun. Here is a video of my brother who got MMBasic running on the STM32F746 Discovery Board: https://www.youtube.com/watch?v=5g3-ztufoNM More infos about on my blog: https://mikrocontroller.bplaced.net/wordpress/?page_id=787 Or her in this forum: https://www.thebackshed.com/forum/ViewTopic.php?TID=7969  Edited 2025-05-21 00:06 by ManiB |

@ManiB, That is early work (2015). 10 years ago... wauw... Volhout . PicomiteVGA PETSCII ROBOTS |

In fact, this was a very early time to port MMBasic to the STM32F746NG MCU. I did a quick search here in the forum to find out when the first versions of CMM2 were released. Overview of Colour Maximite 2 Versions CMM2 (First Version) First Mention: June 2020 Processor: Microchip PIC32MZ EF (ARM Cortex-M7, up to 200 MHz, 2 MB Flash, 512 KB SRAM, 176-pin) Source: TheBackShed.com, Silicon Chip CMM2 G2 (Generation 2) First Mention: December 3, 2020 Processor: Microchip PIC32MZ EF (ARM Cortex-M7, up to 480 MHz, 2 MB Flash, 1 MB SRAM) Source: TheBackShed.com (?), Silicon Chip (August/September 2021) CMM2 G2 V2 First Mention: October 2, 2024, with development starting April 4, 2024 (schematic) Processor: STMicroelectronics STM32H743IIT6 (ARM Cortex-M7, 480 MHz, 2 MB Flash, 1 MB SRAM, 176-pin LQFP) Source: TheBackShed.com Edited 2025-05-21 06:16 by ManiB |

AFAIK the CMM2 has always been STM32 based. The PIC32MZ family uses MIPS core, not ARM core. But I think the 2015 port of MMBasic to STM32 was before CMM2 was concepted. Volhout . PicomiteVGA PETSCII ROBOTS |
