It was??? I never knew that.

Cool! I have a feeling a lot of 8x classics will be remade for Nspire now.

So you want to make a java compiler that compiles to z80 machine code?

Ummm it shouldn't be too hard. I'm not making it or anything for the contest though. I think the hardest part would be to play the actual game to figure out everything that needs to be cloned

I'm going to enter if I can finish my game fast enough, it is a mode 7 style racer for Nspire. Do I have to make sure that my program works on touchpad calcs, (?) because I don't have one.

For my purposes, it will be fine, as I don't expect to have maps greater than 64 or so blocks, and 1 unit in my engine is a block.

Apparently ARM7 does not natively support long long integers. So that means I would get odd results if I tried division with any number with an absolute value of over 1.
Would (a << 8 ) / (b >> 8 ) work? I would still get an overflow if I used anything over 65536 in fixed point, but I don't think I will get to numbers that high.
Also, is there a tag to disable smileys?

But the way I did it would prevent overflows, because I am only using 32 bit integers the whole time. In my case, not getting the integer part right would be worse than getting a tiny part of the fractional part wrong.
Yes, I'm using signed numbers. Will that introduce problems?
Also, am I understanding the division correctly? a / b in fixed point is [integer part of a]/b?
Can you use 64 bit numbers on the Nspire?
Hey, it's my 888th post!

Thanks! Also, just want to make sure, am I doing multiplication right? product = (a >>  * (b >> product = (a >> 8 ) * (b >> 8 )

For the contest, I am doing this thing that involves a raycasting. I would just use bwang's engine, but I'm guessing it would hurt my originality score, and it is kind of slow with all the features he added and the fact it uses floating point math. So, I'm writing my own, with fixed point math and less features, but I can't wrap my head around fixed point division. Can someone explain it to me? I'm using a 16.16 format, if it matters.

no, even better, a clone of the pinball game on windows xp.

Thanks, I may finish that then for the contest or I might use some other ideas I had, which are more original.

Oh, that might explain it. I always forget about PTT.
I wonder... if PTT is so important in schools, does this means schools might eventually ban the regular 83+ and 83+SE in tests eventually? (Since they do not have any PTT feature)
My school actually already banned EVERY graphing calc from tests. Luckily, we're still allowed to use a graphing calc in class.
More schools should just do that, though when I was in high school for math (i know i turned 14 this year, don't ask) we just had to use a class set of calculators, which the teacher handed out at random.

Cool! I might give this a go, but I'm not too sure if i will have the time because I am moving, and also have various things i am going to over the summer.
I was working on an indestructotank clone a while ago but the project stalled and I was thinking of reviving it completely from scratch. I never released any screenshots or copies of the game, all i had was a few banners in my signature, would I be able to enter it in the competition if i finished?
