<br />
Some [[MVS cartridge]]s were shipped with a special NeoGeo Pocket cartridge-like daughterboard replacing two of the [[P ROM]]s on [[PROGLBA]] PROG boards by flash memory.<br />
<br />
This practice is thought to have been used for shortening the time-to-market of some games, allowing to start production without having the games fully debugged. This board allowed easy servicing of first versions of the game programs: If a critical bug was found, carts could be easily reprogrammed using SNK's NGPC flash writer which was certainly sitting somewhere in their [[SNK factories|factory]].<br />
