A member offered to copy the code but I'm hesitant to ship this thing across the country.
I'd love to find someone in NJ if possible.

Some quick research seems that many EPROMS seem to last a long time as long as they are good quality chips. These are Intel 2732-A and seem to not have an issue with bit-rot / leakage whatever as long as they are protected from sunlight.
These chips have labels over the programming window and I've reassembled the cartridge so its well protected.

Interesting factoid I found out: All Adventurevision games are actually EPROMS - I've never heard of the AV games going bad.

I played the game a bit and my feedback is its wickedly hard. I'll give it a go again today and see if I can post some video. Based on some video I found of release version it seems like the difficulty is high on my Proto version.

Anyone in NJ metro area that can dump the ROM contents?

Thanks!
