Hi, Byte Knight! I joined this forum just so I could contact you on your CVFB upgrade! I was just talking to my girlfriend's son last night about how great the Colecovision system was and today I googled one of my favorite games: Frenzy! That brought me to a couple of YouTube reviews on your upgraded system. I am very impressed!! I have 2 broken original systems and I miss playing many of the games I used to play! Please PM me and let me know the details. I haven't purchased the CVFB system yet because I read a lot of bad reviews on it mainly concerning the new controllers but I know your upgrade can bypass this. I think I still have the old working Sega controllers that I can use with this.
