the production of a bootcd would have to be done on the actual sega cd pressing machines and would be a total waste of money (now how many would be buying one of those? prolly not even 100 people), especially cause any cheapo import adapter cart can play imports better.
dc does not have a protection against cdrs, so it can be made to boot cd games.. saturn does have a protection.
the swap will NOT defeat the country protection, ONLY the cd r protection, by reading the protection ring off an original, and the game off the copy.
