I will say about ProbeRB and my Pleo, I use it on him at day 2.
It's great and I alway curious that's real dev's voice or CG...It's works smooth and I can use stand mode to default boot.
But sometime it's crashed and make my Scratchie stunned. I can't turn him off. (Last time is this morning.)
Sometime I stand him up and keep saying "starting default..." until I lay him down again and manually power off from ProbeRB's interface. And this problem sometime off and on didn't help until I remove the card.
I don't know what bugs are inside but if I didn't meet with those problems, that's absolutely fine.
I'm waiting for some finer-sculpted version, or open this sources. (As I want it for study.)
