The procedure that takes an MVS cart and converts it into an AES cart playable on the home system. This involves the use of a sacrificial cartridge (sac cart) as a host for the new converted cart. The chips in the sac cart are removed (if done properly, (1) the sac cart can be restored or (2) the sac chips can be transferred to the MVS cart). Controversial method: Converting a cartridge for personal use is probably legal, selling a converted cartridge is probably illegal. Beware.
