So is there a download here? (and yeah, that can be a little troublesome)
See below.
Are there any plans to support color from the CX?
Perhaps. The CX isn't just a normal Nspire with a color screen. We know it has extra RAM and flash - what else in the hardware might have changed? We'll just have to wait and see.
Yay for that. Will there be another linux-compatible release?

Someone else made that, not me. I'm not familiar with Linux GUI libraries.
Anyway, here's the new version, 0.50:
- Implement enough USB emulation to get file sending to work. This is a big milestone: No more OS-version-dependent code!
Yes, that's right, you can now send documents to any OS version, past, present, and (hopefully) future. - After an error, debugger command "c" now resets rather than quitting.
