Isn't the static RAM address supposed to be the bottom of the g3a stack. Or has that now changed to a new location?

DJ_O FTW. The founder of the greatest calc forum ever and a reliable friend.

I remember thepenguin saying with his sound player was that he only had so many clock cycles to load each byte of data which made loading from usb difficult. But now that you're probably riding the limit with usb, adding compression would take too much time

Here it looks like a look up table would be the best option depending on the number of options, but I'm no Axe expert and don't know how to do that. My suggestion though would be maybe if you could have a list of pointers to the other source files then have the r1 index jump to what it's offset points to.

That's one of the most innovative things I've seen all year for the calc. This will deserve a news article once released for sure. And with 2 gigs I can fit a lot of songs in there especially if they are at reduced quality.

Sounds like an interesting but difficult proc. That gives me an idea to compare the RISC vs CISC architecture philosophy. Personally I prefer RISC which the ARM and SuperH use but many also like CISC which is what the z80 along with x86 use.

Just saw this for the first time and it looks amazing. I remember trying to make simple RCX stuff when I was little, but nothing even close to this. Good luck on winning and I'll be sure to vote for you

I say someone should try minecraft on calc.
Just saying.
It would be like classic mode though
I'm not trying to bash the idea, but Minecraft's graphics are actually incredibly difficult to do (in spite of how simple they look). The fact that the world is entirely customizable means that almost all of the little shortcuts and cheats that are used to do normal graphics don't work. I would greatly love to be proven wrong about the chances of even a limited port of it, though.
I'd agree with you on that. Normally the game world is static and only includes what the gamer can see. So if you were for some reason on the top of an inaccessible hill you would see emptiness behind you. Same thing if you poked a hole in a mountain. But in minecraft there are 10,000's of hidden polygons at any moment so special tricks must be used to determine which are to be sent to the gpu. But then this testing phase also takes many cycles too making coding the graphics so hard.

You should have a function that allows for easy insertion of sprites. That's one issue I have with Mimas because typing out long strings of binary data can be difficult with the small screen, plus it makes the source much longer too.

I did read the bill and it's surprisingly short. A quick change in wording on a single line is all that it would take to fix the issue. The reason why it's so short is because it is an amendment to a previous law. What s.978 does is it redefines copyrighted material while increasing the punishment for breaking copyright law.

Ten years--wow. Ten years ago, I was a six-year-old in a hospital with a teal gameboy color from my dad.
I feel like I just got to know the awesome, awesome DJ, and now he's being torn away. I <3 U DJ
That's unusual. Exactly ten years ago my dad gave me a teal gameboy color, but instead of being in a hospital bed I was on a flight. Anyways it's been a hell of a time with you DJ. I remember you welcoming me into Omnimaga after my first post announcing that I got a Prizm. Then in the months following I was promoted to ARS and then CoT by you. I thank you for not just providing the best calc forum ever and helping me succeed here, but mainly for being such an honest reliable friend that I will always miss :'( Edit: lucky post 777

mathematically speaking it should be infinity or negative infinity which floating points represent properly but for integers I believe it would just be 0 but once again I'm not sure.

If the ARM is anything like the SuperH (which it very much is) then no automatic exception is generated for divide by 0. Instead an undefined result is what happens. For an exception there must be a specific test for 0 before division begins. This would be done as a conditional statement and not as an internal exception processing. I would though confirm this with someone who actually does low-level nspire dev such as calc84

This is awesome!  this will make C coder a lot more fun for me, and probably a lot easier as well. What type of routines does it include at the moment?
Right now most of the routines are for drawing stuff such as sprites, lines, circles. I will be focusing more on the libraries once I get the execution part perfect.

Currently I'm working on the file/folder management and the gui. I hope to have a demo of Walnut loading and running a test program soon.
