That's an option, but a bit on the expensive side, as the minimum order is 4 shells and adding international shipping it's more than I paid for the multicart itself.
If this can't be reliably open I'll leave it as it is.
I would like to replace the internals with a multicart, in a non-destructive way obviously as I don't want to damage the original shell.
But if it's glued it's going to be quite tricky.
I'm trying to open a Vectrex cartridge shell - I've found a couple of videos/examples that explain to remove the screw on the back and... voilà it's open!
But it looks like this cartridge has no screws and I can't seem to find a way to open it without breaking it... Any help is appreciated!
