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.

The Gauntlet from original Colour Maximite ported to the CMM2:
Gauntlet Demo for CMM2

It's a very preliminary port and doesn't use the optimizations that the MMBasic of CMM2 has. The core is too much oriented to the original CMM and your limitations, what I will change someday.

My current objective is to publish more demos and focus only on one exclusive game for CMM2, then after that, I will return to these other games to finish them (Gauntlet and Final Fight, for example).


I must admit, during alpha-testing inside the closed group(before release here), I spent WAY too much time playing this game when you sent it to the rest of the group for testing!  

Awesome game.  And the fact you can code it all in BASIC is astounding, really, when you consider that BASIC was traditionally way to slow for this kind of thing due to the interpreter overhead.  Just goes to show how powerful the CMM2 really is, that you can code a game like this in any form of BASIC!

The original games from this era, were all coded in assembler, which is even harder to program then C, and C is bad enough for me!

Geoff, A couple of more typos:

page 14: 3rd line from the bottome "loose" should be "lose"

page 15: PIN Security - "pin number" twice. Not really a typo but redundant. Call me pedantic and ignore it if you like.

Still reading.

Hi ,
i was curious to know if someone have try this code on the STM32H747I-DISCO board ?

H747I disco board

It's compact , screen is in place , no need vga/hdmi converter and cables all around ;)
And the stlink V3E debugger / Programmer is integrated on the board too.

Little pricey for those that just want to test , but not bad at all for the other that want spend allot of time with MMBasic ;)

Cheers.
Theory is when we know everything but nothing work ...
Practice is when everything work but no one know why ;)

I'm sorry, I left the video processing and went to sleep because here it was one in the morning and I wake up at 6am to go to work. Probably at the time you tried to access YouTube you were still processing.

It won't work. Please no-one buy this board or any other STM32H7 variant and expect the CMM2 code to work - it won't

Thanks very much.  I have reread the manual many times but I still miss these typos.
Much appreciated.

Minor typo in Appendix E of the user manual

Sprites are loaded to a specific number (1 to 50)

should be:

Sprites are loaded to a specific number (1 to 64)

Sorry Geoff, my crap proof reading again

Fonts on the CMM2

Is there a maximum size for fonts? The only reference I can find to a maximum size is in the original CMM MMBasic Language Manual.

  Quote  The FONT command is normally used to load custom alphanumeric character fonts but a font's character can be as large as 64 pixels high and 255 pixels wide.


Nothing in the Micromite docs.

I don't think there is a size limit apart from whats practical.
64 x 96 is the biggest I have tried

You cannot use characters below chr$(32). It caused strange problems when we tried.

excellent information - combined with the CMM2 schematic this demonstrates how the vast majority of pins are already allocated to functions:
CMM2, CPU module pin usage.pdf
(collated from the two schematics by hand - there may be omissions and other errors!)

of interest is that the pins for both the micro-USB and 20-pin JTAG connectors are used elsewhere.

cheers,
rob   :-)

- would it be possible to add the 40 pin GPIO pin numbers?

I realised I had a bigger font.
It's a single character 240 x 240 pixels.
The FNT file required for the single character is 16930 bytes long.
The CMM2 will compress that as it loads but still sizeable.

My FontTweak program gets annoyed if you try to create a font greater than 128x128, but if the font exists it will accept it.

I've done a single PCB version of the CMM2

This is the complete schematic

Motherboard - Project.pdf






There are also the gerbers, BOM and component placement files needed to get them manufactured by JLC. This is very cost effective but unfortunately they are currently out of stock of the processor which makes them manufacturing them rather pointless. They can only do surface mount on one side so you still have do solder the SDRAM and some capacitors on the bottom together with the various through-hole components.

The board can be hand-soldered if you are very confident with SMD. I've done 3 and WhiteWizzard has also completed one.

I was thinking of Maxman where the screen is composed of fonts as I understand it:
  Quote  64,240,97,110

I don't know if Nick is still monitoring the forum and/or he is interested in updating his games to the CMM2 or not. Even if I could do it, I don't think I could share them.
