Doors CSE 8.0 is a shell for the TI-84 Plus C Silver Edition. It is an extension of Doors CS to TI's new color-screen calculator, and provides everything you might expect from older shells like Doors CS, MirageOS, or Ion. Doors CS lists and can run all of your TI-BASIC and Assembly games and programs. It lets you organize your programs into folders, archive, lock, and hide them. It gives you extra features like an enhanced TI-BASIC editor, a clock, lowercase letters, and much more.

This is a Release Candidate, meaning that it's a preview of what the final Doors CSE 8.0 will look like. My Cemetech beta testers have provided invaluable assistance in finding and tracking down a host of bugs, so I am confident that it represents a high level of quality. However, in the interest of making sure that the Doors CSE 8.0 that spreads to students' calculators is as bug-free as humanly possible. Therefore, I urge you to please try out Doors CSE 8.0, run all of your programs with it, explore all of its features, and please submit both positive and negative comments and reports. Let me know about features that you find to function well, programs that work with Doors CSE 8.0, and of course also emphasize anything that breaks. In your bug reports, please include step-by-step directions to replicate your problems.

A final note: As this is a release candidate and likely contains bugs, it launches with a large warning message. Please do not distribute it to your friends yet; a final Doors CSE 8.0 will be available for that soon. Without further ado, download and enjoy!

Thanks! I hope it will limit the unstable versions in the wild.

Important Note: I discovered and fixed a problem with TI-BASIC programs that use Lbl/Goto shortly after releasing that. Please make sure you get the latest version and have at least Build 1207 on your calculator.

By the way, how large is an ASM program icon (such as PCSEBall)?

The PCSEBall icon seems to be 32x32 = 1024 pixels, rather than a scaled-up 16x16 = 256-pixel icon. 2 bits per pixel should be enough to describe the PCSEBall icon, so I'd estimate it takes 256 bytes + the space for the palette (4 bytes if a 256-color scheme is used, 8 bytes if a 65536-color scheme is used).

Perfect estimate. The scheme for program icons (and the headers in general) is described here.

Okay, so if you hide a folder it turns into a BASIC prog, then is useless. Everything in the folder disappears from DOORS but is still on the calc. Also making a new folder with the old folders name does not put the stuff into it. Maybe disable hiding folders?

Yep! I was going to post it to Cemetech, but I haven't logged in since I made my account, so I have no idea what the password is.

Thanks for the compliments and bug reports, everyone. Doors CSE 8.0 Release Candidate 2 is now available; please thoroughly test the shell and its API functions, and report bugs in the Cemetech DCSE 8 RC 2 topic or here.
