Looks like Time Traveler's time reversal cube feature is working so I am marking that game as "Works" on my Dexter status page and upgrading the LDP-1450 implementation status back to 100% under the assumption that every command every laserdisc game will need is implemented and working.
I am going to take a little break working on Dexter to work on Cobra Command for Daphne on the Raspberry Pi (for the Cobra For Collins project) and after that I'll probably get back to work on PR-8210 support for VBI injection.
