I was working on multiple projects at once and finally realized that I just needed to finish MAME. I have been working on it since MARCH

Dreamcast is very high on my Things to do list as it will be relatively quick and I LOVE MY DREAMCAST!!! Although I am considering using the console instead of the emulator to future proof it. And I have an almost complete collection of games for it.
Don't hold me to it

but I would imagine DC may be done by the end of Q1 08
My List Goes As Follows:
MAME - 1 or 2 Months Remaining
DC - 1.5 Months
Clean up Existing Sets (Naming, Cropping, Editing 30 sec, Replacing) - 3 Months
Finishing Extra Content - 2 to 3 Months
Playstation - 4 to 5 Months
I think these are fairly conservative timelines as long as RL stays out of the way.
