Exactly right, DJ. He'll probably end up needing to make a custom routine (or using dialog boxes, like he said).
printf() is difficult to get working because, on the Nspire, it doesn't output to the screen, but to an internal serial port, IIRC.

The nice thing about a custom font is, though, one can create "letters" that aren't exactly letters.  In S.A.D., I use Belthium Crystal Icons, Oxygen Icons, and Lobster Icons as part of the font.

Of course, if it weren't for powering down, clocks could be made for the 83+ using interrupts.

Awesome!

So, is it like Mario Party?

Well, I decided to start putting together this guide a little bit early.  This is a guidebook I will be releasing with the Source Code of S.A.D., and as you can guess, it tells people how to modify S.A.D. to make Real-Time Strategy games of their own for the Ti-83+ series.  In this way, only an intermediate knowledge of ASM is required.  If you understand the first 14 chapters of my ASM guide, you will have no trouble with the guidebook I will be providing.

S.A.D. isn't hard to work with code-wise once you understand what's going on, so I'm hoping people in the future will take advantage and release RTS games of their own--maybe even ones where one can use two or more different kinds of units in their group.  However, I will confess that the reason I'm working on it this early is because if people understand exactly what's going on, they might be able to help me make the game like they wanted to--but couldn't because of lack of ASM skills.  Yes, I'm a little bit selfish  

I'll post .pdf files as I make progress.  Unlike the Ti-83+ ASM guide, there will only be PDF files.

It is my goal to have S.A.D. Alpha Release 3 available in September.  Currently, I'm working on allowing a person to do everything they want with money.  This means that a player can, at the least,

1. Build Refineries
2. Add Processing Units so that more Belthium Crystals can be mined per second
3. Purchase Items
4. See how much money he currently has
5. Recieve a notice if not enough money is available

I'll keep everyone posted, but as of yet, there's no decent screenshots.  I will say I've finished with getting the "Add Processing Menu," so I'm working on construction of processing units.

I never tried that one. I was afraid it would be a bit too simple despite the 3D or choppy framerate. Is it the case?

I don't know.  It had a good review...   I tried it once, and don't remember if I liked it or not\

EDIT: It's actually decent.  Certainly the best coaster game I've seen for an 83+

How do those purchased items show up? Are they icons on a person's signature, or what?
