Does that mean 128mb of flash and 64mb of ram, just imagine what we could do with a color screen and that much space. Come on TI, you know we'll find a way in eventually.

If there's 84 emulation, how do you change the keypads, the seam below the arrows makes for a small 84 keypad. At least the cx doesn't have wings like the old nspire, hopefully it is more pocket friendly

Wow, I just read this thread and saw the awesome pics. Gave input on the survey, I would definitely pre order if it was around $200

Thanks, that worked, although is there a way to do it without messing with the next byte?

I have a tilemap that is in bits. When I use this code, it works except when I have V=60 and W=50, the bit subroutine always returns 256. When I use any other dimensions, it returns 1 or 0.
W=60
H=50
.W=Width of map, H=Height of map, A=Start of appvar (returned from getcalc)
sub(BIT,Y*W+X^8,Y*W+X/8+A,°U
.Bitnum, Address, Where to store the result of the test
.Code
Lbl BIT
{r2}er1->{r3}
Return
It would probably take up less space putting this code inline, but why isn't this working for a 60x50 map while it works for any other dimensions.
EDIT: I got it with some other sizes like 59x49 and other numbers around that area, but what is causing the bit checking to return 256?

I don't know if I touched a section of memory I shouldn't have but every now and then when I compile a program the screen will turn off. When I turn it back on it will show that is crashed right after displaying the text that says compiling and then proceed to the ram cleared screen. I havn't figured out how to reproduce it though, it seems random.

I'm no expert in asm but it looks like you're using bcalls. My guess is that quigibo doesn't use _ClrLCDFull for ClrDraw. For DiagnosticOff, my guess is that he resets 0, (IY+12h) and 5,(IY+0) but idk if he went for speed or size with DiagnosticOff. But again, I only just started asm.

Do you have to sign the os before you send it. I patched 2.53 and it failed validation. Although I patched the copy on brandonw.net because I couldn't find an unpatched copy of 2.53. Had to go back to 2.53 only with the xlib patch.

I'm probably missing something, but is there a way to get/set the value of a single bit in axe?

That's how I was doing it. At least I wasn't missing an obvious command

How do you append data to an appvar? If I have appvar A which is 500 bytes, how do I add 100 bytes to the end of it?

I'm not actively working on any projects right now. Most of the programs on my calc right now are attempts at fast graphics engines of all sorts and test programs for sound, keyboard, ect. I made a few xlib and pure basic games but those are lost somewhere in my backups.

I have been on Omnimaga for a few months and just noticed the Introduce yourself board. I read the forums ALOT more than I actually post so that's why my post count is so low even though I frequent Omnimaga.
I own a TI-84+SE and a TI-89T. I know BASIC for both, axe on the 84, and C on the TI-89. I'm currently attempting to learn z80 asm with hotdog's asm guide. I tried to get through asm in 28 days about a year ago and only made it to day 10 or 11.
EDIT: The game

The TI-89 and other 68k calcs have 24-bit memory addressing, so there is no need for swapping any memory cause that's 16MB of space to use. The OS is run from the Flash ROM (I think the Flash is fast enough to handle it, since the processor runs at ~15MHz or less; I don't know the exact details but different models have different processor speeds). Normal programs are loaded into RAM. I have no idea what happens with applications.
Hmm I was sure the 89T had 2.7 MB of flash or something O.o. Does it really have that much hidden memory?
I think he means that it is capable of addressing 16MB of memory. The 89T has 4MB of flash with 2.7MB for the user. There's 256K of ram with 188K for the user.

I thought the 83+ would go first. Maybe they were loosing money on the se. You know, 1 extra mb of flash memory costs alot these days.
