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. |
||||||
You, Sir, are one sad individual. ;) |
||||||
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 |
||||||
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.  |
||||||
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 . |
||||||
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 . |
||||||
@ManiB Wow , so long ago , i worked with Uwe on this project , i added the Sprites , Polygon , 3D Functions to the interpreter It was bad that Uwe don't have time to continue the project. The STM32 was the best at that time , for now i don't have check but for real power i think the teensy 4.1 is the only one to beat the STM. And greetings to Uwe when you get in touch with him |
||||||
Yes, I remember. I bought an STM32F7 Discovery board just because of this MMBasic project and thought it was so great to be able to write Basic programs that were faster to execute than if you had programmed in assembler back in the 80s. Unfortunately, my brother decided to stop updating his blog, which meant that the website was no longer accessible and then the webspace was deleted;( To my regret, and probably also to the regret of his fan community, a great documentation on the STM32 microcontroller has been lost. I have therefore decided to put his work back online here: https://mikrocontroller.bplaced.net/wordpress/ |
||||||
Just to bring the lemming idea back into the spotlight for a moment... The following short demo on a C64: https://www.youtube.com/watch?v=fbXIdK3o3NU And here is the explanation: https://www.youtube.com/watch?v=uZ1atMUOUMU It’s just unbelievable. Matthias |
||||||
Excellent!   |
||||||
Fortunately, you can find the animations online Amiga Spritesheet or bigger Lemmings 16x20 Edited 2026-08-11 15:53 by Martin H. |
||||||
Hi Martin, I think the 16x20 is not very suitable for a 320x240 resolution screen. I have a lemmings core working with 13x20 (mouse control on pico !!), and despite they look great, and move great, it will be hard to make a nice landscape/world for them to move in. The landscape can scroll sideways, but vertical scroll is difficult to play. So your total height is only 15 lemmings high (not much falling/digging/parachuting to do). I started re-writing my core to make use of the 8x8 (classical) lemmings. And it helps that Peter added collision detection with the background. So the game is in essence possible now. Volhout Rodents demo: that is really using every aspect and bug inside the VIC2 chip.... Edited 2026-08-11 17:53 by Volhout |
||||||
Hi Harm, You’re probably right, but I’ve written a little demo/benchmark here anyway to see how many Lemmings can be moved. lemtest.zip |
||||||
You have seen this ? lem_core3.zip 100 lemmings walking...(the visible ones...) Incidental you see a lemming flickering, but those are 2 lemmings exactly on top of each other. Volhout Edited 2026-08-11 23:03 by Volhout |
||||||
Volhout I’ve put together the complete set for you here as sprites and CSUB file. These are 318 converted Amiga sprites which, to allow for freedom of movement, are still 16x16 pixels in size. sprites.zip  You can, of course, create a Lib from it or read the BMP using BLIT FLASH. See which works best for you. Have a good Weekend Cheers Martin |
