Claude and I have been working hard on bringing you a nice chess game just for Synchronet sysops and I'm please to announce SynChess 1.0 is available for you in giblab.
Installation is easy and instructions are included in the readme.txt file. I've not tried the install-xtrn.ini so if someone would like to give it a go and let me know, I'd appreciate it. For now, it just has player v computer.
I was wondering, what is jpegXL? I'm using SyncTerm, and when I ran SynChess, I saw what looked like fairly standard CP437 graphics with ANSI colors (with the chess board with blue and cyan squares). The only mention of jpegXL is once near the top of the instructions, so I'm not sure if I need to do something to enable jpegXL or not (and I don't even know what jpegXL is).

It's a losless image compression format that CTerm supports. Make sure you have a recent version of SyncTERM. It looks like it was added over a year ago tho.
Thanks for the other feedback.
Your chessboard should look like this:

But wow, what a fantastic BBS door! Just amazing! Good work Nelgin/Claude! :-)
I set up SynChess on my BBS, and it looks like a good chess game.

Is it multiplayer? And where do you get it, vert?

It looks similar to that, but I'm not seeing the graphical chess
pieces, just letters reprecenting the pieces.

I'm using a fairly recent version of SyncTerm, version 1.8b from
February 28. So jpegXL should just work? There's nothing I need to do
or enable to get jpegXL to work in SyncTerm?

I just had the same problem, and Deuce (in IRC) helped me to realize I didn't have any "libjxl" libraries installed. After installing them (don't forget the -dev ones too), you'll have to re-build SyncTERM to get things working. All good here after doing that.
Mine looks like that (using SyncTERM v1.8b). It's an awesome game! I was a little confused by this prompt:
Checkmate! You win!
(P)GN (A)gain (Q)uit
I do kind of wish the computer moves were a little more obvious, slow or animated or something. They computer moves are so fast, I usually had to look at the move log to be able to tell what/where they moved.
But wow, what a fantastic BBS door! Just amazing! Good work Nelgin/Claude!
Oh yeah, I wanted add: I found the game to be very intuitive and the mouse integration "just worked" exactly as you would expect. I was very pleasantly surprised!

For SyncTERM to support JpegXL, it needs to be running in a graphis screen mode (i.e. not Curses or ANSI) and it needs to be built with the proper dev package installed. Did you build it yourself? Check the Build Options listed in SyncTERM, if "JPEG XL Support" isn't checked, then you need another build of SyncTERM.

Another thing I noticed - In the readme for SynChess, it says the access requirements includes "80 COLS" - Is that correct syntax? For some of my doors, I've used "COLS 80", so "80 COLS" seems backwards. I'm not sure if Synchronet will accept that as valid, will it?

The copy and mask features of SyncTERM are perfect for animating things like this. Point Claude at exec/syncterm-bounce.js for an example he can work from.
Aren't you idling in the IRC channel...?

Thanks to Deuce, there's now a nice animation for both ANSI and jpegxl versions. I was going to have variable speed but I don't think it's necessary. It's not intrusively slow.
Yeah, I played it right away and really appreciated the changes! It's really set a new standard for door board games, I think.
Thank you so much for the compliment. I'll have to see what else I can come up with.
I didn't know about that jpegXL before this. I think that could potentially be useful for a lot of things.
As Digital Man says, this is a new bar for people to jump. It might be nice to have a bit more documentation that's easy to comprehend for the uninitiated :)
I'd never have got this done without Claude and a bit of Deuce for the animation.
