With my unhealthy obsession for the system & no sense of priority in daily life, I just finished a quick implementation on Peg Solitaire. Both English and European variant can be played.

Nothing is gained once the puzzle is solved.

I think I'll try and add music to this, since I still need to dive into some implementation details for that. And probably some animated background to distract you from solving the game.

Controls:
- Select a marble with A, and set it to an adjacent target cell with A again.
- B cancels the first selection
- opt1 returns you to the intro screen.

If there are bugs in there, please let me know.. I was really hasty on this one.

Cool, I will check it out!

Great little game. I got down to 3 pegs on my first try.

I'd really like to see a screenshot of a solved game I never solved a single game so far, but read somewhere that the strategy is to work symmetrically.

Nice implementation. Although I did not solve it on my first attempt.

Very good job programming
With a little music would be perfect.
I finished the two versions and I saw no bugs.

i've been playing this game in the form of T-Break on the Bandai Pippin lately, pretty addicting. Will have to try this out once I get some free time to better learn how to use my flashcard

Great to see people trying to solve it I still haven't solved it... but good to hear it looks like its bug-free. Now to fix some tune..

Don't forget a nice background. I like Gremlins style of adding atmosphere to a board game like this.

Ah good ol' HeroQuest. Pretty entertaining game, and another good example of what could be done on the Lynx. I was thinking of some nature scenes. Some running water with Eric Satie's Gymnopédie would be great..

LOL I need to re-learn how to use my Lynx Flashcard. LOL

Cool Thanks Kari for that solitaire game as our Lynx are still hungry

[Ninjabba]

Here's an update of the Peg Solitaire game:

- added a few more boards (5 in total)
- added some gfx
- added the first chiptune I ever worked on

Controls are still the same

I mainly use this project as a test case for adding sounds/music. I am aware of the bug that when switching games the sound will keep hanging at times/resetting when starting a new game and whatnot more. This is mainly caused by the fact that I haven't figured out how to stop the music yet.

I'll post the source of this project later on, but gotta run for work now

Edit:
Thank you Sage for providing me the sound drivers! Credits for the tune go to Empty Space, got it from Mod Archive: http://modarchive.or...eid&query=89762, and mixed by me using chipper

Thank you, Ninjabba

Yeah, just that the picture has only 16 colors...

PS: How about using
asm("jsr SndStopAll");
or
asm("jsr SndPauseOn");
to stop the sound.

Aren't the 16 colors one of the charms of the system? I have no idea how to use more colors

That did the trick btw! Attached is the bugless (?) version

Good point about the high colored images for small games.. its quite incredible that you can display 2000 colors at once on the screen! If I hadn't seen the slideshow demo before I'd say its black magic. I'll start asking around in the programming forum

Changing colors like this during the active display is a very good tool on the Lynx. But it can take some time to think of good ways to make it seamless with a game.
If you just want to change things with a one scanline step, it is actually quite easy. Just have one of the system timers running in sync (or as close as possible) to timer 0 (HBL), then use it to feed another timer. Then you have a line counter. I usually use timer 1 fed into timer 3 for this. This is done in a few places in Zaku, like Marine Zone and Emp's battle, but I have been trying to find more interesting uses for it nowadays.

You can also change the colors mid-scanline for a million-jillion onscreen colors.
But of course the more you do this the more the 6502 is borrowed from running the game.

I'm assuming the techniques for more colors are:

1. Flip between two palettes and screens each VBL-more perceived colors, but also some flicker.
2. Change palette mid-screen one or more times, using HBL. Increase the overall amount of colors on the screen, but color use is still limited to 16 colors per scanline.
3. Mid-line changes, as above, but more CPU time involved, and still some restrictions on color use.

These same techniques are used in quite a few other systems, Atari 8-bit as one example.

sure, hasn't changed in the last few years (since CGE slideshow)
just the algorithm got better
