Okay, I guess I am stupid too, I didn't even realize this thread was 4 pages long. Oh, well.

What I remember about the built-in game .. is that if you put a ROM in there .. that's all you get!  You cannont use the cart slot for any other game.

I've been wanting to tinker with this, when I get time :roll: I figure thers got to be a way to instal a contact switch in the load slot to diable the onboard chip somehow,, What I really would like for this is a Mulitcart Chip? maybe like one of those junior Aussie units with the on screen display (but of course in NTSC
Kevin Horton has done this without needing a switch. Read my previous post and follow the link

You didn't read through that site carefully enough.
2600 carts have two ground pins
that are shorted together by the cartridge board.
You can break the ground path for one pin of the cartridge connector and give it a pullup resistor.
Then it will be at 0v when a cart is plugged in
and 5v when one isn't. This gives you a enable signal for an internal rom (maybe put it to CE and /A12 to /OE or something)

Hey guys,

who would be interested in mod-kits for the 2600 video-out modification ? Simply respond with 'Me' ! If you are not interested - don't post. It will make it easier for me to figure out if it would be worth the trouble.

Thanks
-R


Me :D
