Would he be allowed to distribute patches?

Ah ok, I thought they were copyrighted. That's good, then.

Of course, sound support would be spectacular

I've been playtesting it along with friends in school (only at lunches and free periods, I swear! ), and the most important features that are still missing are the map and save/load game support. I'll work on them this weekend.

I have to test it in my touchpad too. Unfortunately, I lack a Clickpad.

First of all, many thanks to Omnimaga for this spiffy new subforum!

In other news, the new release won't be out yet, but rest assured, I am working on it; However, I've hit some strange crashes and it's generally taking longer than it should.

If freezes on the "Loading" screen when I run it using the clickpad.  I have to pull the keypad and pull a battery to get it to go back to normal.  Its been a little while since I tested it, as I have not used my Nspire much, but when I get a chance, I will test it again!

Looking at the input code, I've found the ESC key was mapped to both right strafe and exit on the Clickpad . Since there's a crash on exit, that might've been it.
Unfortunately, it could also be related to some other strange issue. What OS are you using, by the way? I've only ran this on 2.0.1 CAS and 2.1 CAS (I don't have access to any other Nspires).

I've managed to fix all the originally-alloca statements (the memory wasn't getting freed due to an extremely embarassing bug...), checked that every malloc() has an equivalent free() statement and that all files are getting closed, but the crash-on-exit still remains.
Although now, it's giving me an unaligned_write_word error instead of an invalid processor mode. I don't think that's particularly helpful, though.

Except for unfreed memory and open files, are there any other things that might be causing a crash on exit? As you might have guessed from looking on my code, I'm not very good at this C thing (give me assembly or python any time!).

Tried it on the Touchpad, but cant find the Use key.
I tried looking through source, but couldn't find any mention of it being there, unless I overlooked it.

edit:unless this is it, but I cant tell if it is for the touch or the click, unless it's universal.

if (isKeyPressed(KEY_NSPIRE_CTRL)) {
event.type= ev_keydown;
event.data1 = ' ';
D_PostEvent(&event);
} else {
event.type= ev_keyup;
event.data1 = ' ';
D_PostEvent(&event);
finally had time to try it, yup that was it, disregard post.

Good news!

I updated my version of this yesterday and I tried it with the clickpad keypad again - and it works fine!  I guess I must have been using an old version or something by mistake!

That's great to hear! I was beginning to worry there for a bit.

I've tested it on my Nspire Touchpad and it appears to work great the only error I've encountered is that it crashes when I hit ESC. I've also found that is easier to see when the colors are reversed. Would there be any way for it to stay reversed permanently?

Yeah, sorry about that crash on exit. I've been trying to fix it since day one... About the colours, I agree, but I've experimented with a permanently reversed palette and it just looks weird (hard to describe, just looks wrong in some way). Because of that, I'll try improving the palette instead of just leaving it reversed.

Meanwhile, I also have good news! The automap is now fully functional. Like everything else in this game, it's a bit hard to see, but still helpful enough. I'll work on making the player arrow bigger, so its direction is more obvious.
No save support yet, but I've got intriguing news regarding the crash-on-exit (note: may turn out to be nothing)... if I run include the "intmask= TCT_Local_Control_Interrupts(0);" line at the beginning of my code, random pieces of my code that worked before start to crash (the PC register somehow gets reset to 0x0000).
Also, I've run the crash-on-exit through a debugger, and it definitely crashes after all nDoom code has finished execution - meaning some memory critical to the OS (or possibly the exit routine of ndless?) is getting corrupted.

OK, here's the latest release, and also the last pre-beta version; All that remains to be added are savegames, and we're out of alpha!

There are two main features to this release: One, there's no more crash on exit. You can run it as much as you want, and the calculator doesn't restart or explode or anything... at least so far.

And the second feature is something everyone will celebrate: Improved palette!

The difference might look big on the emulator, but on real hardware it's completely incredible! I mean really, a complete transformation, leaping from an image barely visible at the best of times to something that can even be played in a dark room illuminated only by the computer's LCD monitor!

The culprit? Palette data was shifted by one bit.
Yes, really. Turns out, I did all my colour->grayscale conversions accurately, but misread Hackspire and thought palette data was stored in bits 0-3, when in fact it was in 1-4. Essentially, this meant only 8 colours were being used. Fixing this doubled the amount of colours displayed, improving things immensely.

Next feature? Savegames, and improved Clickpad controls. After that, we're out of alpha!
