Again, thanks for all the help!
I have a much better understanding about how these work.
While it's a pity that some don't, I think the programs that *do* work on the Nspire will be more than enough to keep me busy when I happen to be bored with nothing but my graphing calculator.

For something with a bit more academic focus, I've heard that the BASIC on the 84 is actually more powerful than the one on the nspire; does this mean that if I start, I should do it on the 84 keypad?

Hello, I've recently gotten my hands on an Nspire and I've managed to work my way through infinite reboots and a whole lot of googling. It seems like I'm stuck on a few things now.
I have Ndless 1.7 and OS 1.7, making my 84 keypad OS 2.48

1. I know there are programs for the 83/84 family that don't work on the 84+silver keypad, but is there any way to tell other than trial and error? Pheonix 4.0 works fine (I have MirageOS 1.2 and the nspire patch)
However:
The Renegade level pack works, but the game can't seem to detect the Jupiter level pack.
Simcity, Gemini, and the french Doom with HUD at the right both have working menus but as soon as the actual game starts, the calculator crashes and gives the "ram cleared" message.
Geometry wars will also enter the game, but freeze completely; even if I pop the batteries, it will still go to the initial screen. (so I had to use the reset button from the back)

2. The software won't recognize .z80 files and call them incompatible types

3. just a minor annoyance, but is there any way to reduce the large amounts of flickering and faintness of moving objects in games? Especially the gameboy colour emulator for the Nspire keypad.

Thanks for your time!
