This is obviously the very rare Atari 2600 early prototype cart that many people are looking for. Congrats!

I'm trying to modify an NES to do just that, rad!

Wow, nice glitch.  I like that you kept playing rather than trying to fix it

Sometimes that's all you can do.

I have memories of playing ninja gaiden 2 and SMB3 with jarbled graphics because I gave up trying to get the cartridge to load correctly.

lol, i fixed the issue. it was from the nes toaster model. Half The pins behind the connector were not well pushed to the connector strangely. so i pushed them back with my finger and it's working great now.

You can get the same picture if you remove the CHR-ROM chip from cartridge (or disable power line).
