It would be quite possible to ship hardware that allows dumping... if anyone that is interested in getting a dump has that available.
I'm thinking a cartridge in-between adapter, then direct a read of the cart to disk (perhaps with reinsert and reboot and a few dumps), which can even be done from BASIC with a few lines of code - like when saving other roms from the computer to disk.
BTW: There's no reason it should be any different from Jelly Monsters, is there?
The solutions already exist, yes, there's a program or two from Mike on these very forums. A cartridge adapter with a switch to turn the lines on/off (so you boot with it off, and then turn it on when the Vic-20 is powered up) and run a dump program from BASIC to save to disk from all memory blocks.
Just tried to hint that all that is needed is to send an adapter to the guy that has the cart... if it's important.
Seems to me it's the label that is rare and probably not much else but you never know until you've checked. I wonder why they called it PACMAN and not PAC-MAN.
Maybe because it was Puckman in Japan, and the hyphen was only added in the West? Have to say though, it's quite remarkable how the Western name is now the de facto call, even probably back inside Japan.
That's right, they didn't use a hyphen in Puckman, looks like there's a small space though in some googled images.
I think Pac-Man rolls easier in the mouth than Puckman... but who knows.
So the Japanese aren't much for dumping roms? Seems in all this time someone would have made a dump.
Wired.com: And of course, the game was originally called Puck-Man, but the name was changed for America because someone might vandalize the “P” and turn it into an “F.”
Iwatani: Yes, the U.S. subsidiary said that that would be bad. We wondered, what should we do? And decided to change it to “Pac.” Then, after the American version came out with the “Pac” spelling, we used that for the entire world.
