The first week (7/26-7/30) is gonna be:
All That (12:00am, 2:00am)
Kenan & Kel (12:30am, 2:30am)
Clarissa Explains It All (1:00am, 3:00am)
Doug (1:30am, 4:00am)
Of course, the 2nd episode of each is the same as the first one, so I guess it's like you can watch from 12:00-2:00am or 2:00-4:00am. They run each block of shows for a week and it changes each subsequent week after.
Some other shows expected are:
The Adventures of Pete & Pete
The Amanda Show
Are You Afraid of the Dark?
CatDog
Double Dare
GUTS
Hey Arnold!
Legends of the Hidden Temple
Rocket Power
The Ren & Stimpy Show
Rocko's Modern Life
Rugrats
Salute Your Shorts
The Secret World of Alex Mack
I am so so so excited for this because I remember like 5 years or so ago they had the channel GaS that showed all the old Nickelodeon game shows, and I was very disgruntled when they canceled the channel. This is like the best news ever, and even though the hours during the week are late (who are we kidding though, real 90's kids are in college now and never sleep anyway, lol), I can still DVR and watch it over and over and over again.
