Okay, I implemented an attacker AI. It's still not complete, but it is doable, although it takes some time for AI to think (around 20 seconds or so, depending on legal moves that it can make)
There are probably tons of bugs, like what you see at the end of the screen shot (it's 4 minutes long -_-;; most of the screen shot is AI thinking   )
Shieldwall not yet implemented, victory condition not yet implemented (well, it does check for victory, but I haven't yet wrote the code to tell you that you won or lost, and ends the game), Defender AI not yet implemented, etc. There are bunch...
The Attacker AI is mediocre at best, because it doesn't search the whole board for the good position. It only searches few areas, so sometimes it misses a real obvious moves (like surrounding the king to win).

Oh, btw, when you try to quit the game, it will give label error, because currently the program is split into many subprograms to make my life easier coding. So if you want to quit the game, just press 'on'.

Otherwise, I think it's pretty good. If there's any kind of bug that you find, it would help me a lot if you can tell me^^

Since the file names seem to be already used, download the game
in TI group file
in zip file

how do you change what you vote?

Well, I only tried it once on calculator, but on WabbitEmu, I was able to recreate it a lot of times, even with ram clears, all memory clear, etc.

Right after all memory clear (in wabbitemu):
RAM:24317
After you get memory error from too big of Ans variable:
RAM:16129
After making program named 'A' and recalling the answer 1 time:
RAM:7925
After recalling the answer 2nd time, weird stuff happens.

I voted for TI-Basic, and Celtic III. Although I never used Celtic III, I use xLib and many other asm libraries.
I tried learning ASM, C++, and BBC Basic few times, but never really got into it. Axe, I will try sometime in near future, but I just want to finish all the projects that I have right now first.

Finally... I got some progress on AI. The attacker can *sometimes* eat white piece. There are still a lot of debugging to do, because there are times when attacker doesn't move at all (which is illegal btw).
The thing is that, it is kind of slow It takes around 10 seconds for AI to think and move, but I only implemented like 1/4th of the whole, functioning AI. I guess debugging and working with it might show me some optimization... This AI program takes about 2000 bytes.
Hopefully, I can get functional yet not so slow AI by the end of the week

I did this on TI 84+ SE OS version 2.43...
May be it's only for TI84+SE?
Or may be, it's because it doesn't have extra ram (my hardware doesn't have the extra ram, because it was made later than others)

Okay, I was trying to purposely make a program larger than ram. So what I did was to make a super long string until the ans variable is biggest and paste it into the program. I used 'F' because it's 2 bytes
If you see the screen shot, during the second paste, the calculator pastes in other tokens, seemingly randomized. I am guessing these are random hex tokens? I first found this out on calculator. There's no way to stop this unless you take out the battery, which causes ram clear. Leaving it for like 5 minutes, the calculator turns off, then when you turn it back on, it gives you ram clear.

Usually, I thought that what you are trying to paste is larger than the program can support, it doesn't let you paste, but I guess in this case I was wrong. May be because I was trying to paste string, not program?

It just baffled me, so just throwing out there. And I backed up all my stuff before doing this, because I knew something bad might happen  It only gave me ram clear, so... I guess it isn't too bad
