|  SCONNEX 1.65 for the +4.
SCONNEX is a version of the famous 4-in-a-line game, written to work on almost any computer. It can compile to work as an SDL2 app (PC or Android etc), or a zx81, Spectrum, C64, C16, Vic20, Pet, app, or as a C99 terminal program. It is open source, released under GPL3 licence.
Download latest version from Github:
https://github.com/orac81/miniapples/raw/refs/heads/main/sconnex-latest.zip
COMMANDS
1-9,A-C: Make move
N: New game
X: Change board width
Y: Change board height
I: Change play level
G: Make computer play
T: Toggle 2-player mode
H: Help screen
Z: Auto-play, space stops
V: Change gfx mode.
Q: Quit
You can play any board size from 4x4 upto 12x12. You can use the program in two player mode for human v human games, or to set up a position for the computer to analyse.
Source, and scripts for building with VBCC (6502) and Z88DK (z80) included.
It is still a "Work in progress", I am still getting to grips with VBCC and z88dk. The search is a simple AlphaBeta tree I have published as a "sample" before, at some stage I will add sorting, iterative deepening, etc. As is its like the old chess programs where you choose search depth levels 1 to N.
Even so it plays quite well, even on a 1mhz 6502.
(BTW My first attempt at this program was published as a type in in PCW magazine Jan 1983!)
NOTE: currently this version isnt running on the c16. I will fix this later..
Anyway, more later, enjoy!

You added a duplicate entry of Sdl-Connex, the best choice would have been to keep a new version in the same page. I'm far from a PC but hope that @Csabo can handle the whole thing.

Sorry, I couldnt really figure out how to add the download files to the entry anyway. I will also make a small change to the +4 entry, I located the chrset above $4000 for tests, it should run below that for the c16.
This version is a true +4/c16 version, rather than the text version.

No worries, Adrian! It's super simple:
- go to the existing record (SDL-Connex)
- click [ Upload PRG file or screenshot ]
- enter 1.65 for version and upload
That's it  If you're unsure about any issues like this, just PM me (or email... or post on the forum).

I have uploaded a new version SCONNEX 1.66 which should run on the c16 ok.
https://plus4world.powweb.com/software/SDL-Connex
I didnt update the source yet, its just 2 small changes:
UINT PTR_CHRSET = 0x3800;
#define COL_EDGE 0x43
BTW I found the c16 hardware flash useful, you can flash the winning line just by setting the colour.
I did have thought, a toolbar (like the SDL ver) with a mouse/joystick pointer could be added, even in UDG mode.
You could just keep 4 UDG chars reserved and use those to draw the pointer as it moves..
No problem luca!
Thanks Csabo, I was trying to "edit" the game entry an add the new version there, rather than the previous screen.
