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.

The programs quoted can be found here: http://www.ticalc.org/pub/83plus/asm/games/mirageos/

Thanks for your time!
