Brandon Wilson has updated his TI-84 PSGroove port to version 0.05.0001 bringing nice new features, and updates.
To quote:
Changes:
The latest version brings about several improvements:
Current status is displayed at the bottom of the LCD:

In addition to the usual jailbreak method, you can now install and uninstall an OS “hook” that allows the jailbreak to work at any point in the OS:

This even works when the calculator is off; the PS3 will turn it on as it enumerates USB devices, and the calculator will shut off after about 5 minutes of inactivity (through the calculators’ existing Automatic Power Down feature).
Now you can shove the calculator and the USB cable behind the PS3 and forget it’s there.
External payloads are now supported. This means you don’t have to re-assemble the application to use a payload different from the official PSGroove one.
These payloads are stored as calculator AppVars and selected through PS3JB’s options menu:

These options are stored in an AppVar called PS3JBOPT, which can be archived to keep it safe from RAM resets.
To convert from a binary file containing the payload data to an AppVar, you can use To8XV (a VB.NET 2.0 program) found here, or you can create your own.
AsbestOS is now supported. The stage 1 and stage 2 payloads are specified in the options menu as above. To use the standard jailbreak exploit, select “None” as the stage 2 payload (which is the default).
