Please note that the
Freeplay ROMs are not the complete ROM set, but rather a
selective subset that needs to be swapped out in order to add the
Freeplay feature. You need to own the actual working game with working PCB and complete ROM set.
The EPROMs used for most of these products are refurbished EPROMs that have
been pulled from other games. EPROMs are shipped in ESD-safe
packaging (ElectroStatic Discharge). Care should be taken
when handling any these devices.
Installation of the upgrade
EPROMs should only be done by persons familiar with handling PCBs
and removing socketed ICs. If you're not confident in doing
these types of things then this site probably isn't for you.
