I released the stage 6 gameplay video.

We will have an intro and a menu screen soon!

Hello everyone

I completed the game intro and main menu implementation. The next steps are to implement stages 07 and 8.

Nice, even without level 7 and 8 it is a complete game now.
Excellent work Leonas.

Stage 7 is coming

@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Is the code here https://github.com/leonicolas/knightmare-cmm2 out of date ?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

At the start of "init.inc", Leo uses "mode 3,12". Page 1 sits on top of page 0, no?

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).

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

If necessary I can combine both layers in one framebuffer and blit it to the screen

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

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

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.

The game looks pretty cool. Is it completed?

Hi Leo,
Out of curiosity, have you made any further progress in programming?

Cheers
Martin

Hello everyone

Thank you for asking how the things are going. After I completed the level 7 development I needed to pause the project. I got divorced and I'm putting my life back on track. I have plans to finalize the last level as soon my life is back to the "normal" pace.

Hi Leo,

Sorry to hear about your travails.

Note that I have some local updates to Knightmare that I made whilst testing it on MMB4L, I'll share them with you when I've got some other things sorted.

Best wishes on returning to normality,

Tom
