It looks like they tried to implement game back-up memory... Why they didn't it in the beginning? At least we would have Garfield: The Lost Levels and The Flintstones (Ocean) well preserved today...--Asagoth (talk) 19:35, 3 November 2018 (CDT)

Edit: Obviously, security was not ignored by them:

"game or other service data is initially stored in SRAM, moved to FLASH ROM, and played. Moreover, when play is to be suspended for another Service or game data, the original game and Status may be Stored in the back-up nodule, which may be a plug-in module with its own BIOS control. Also, in loading the FLASH memory via a high Speed Writing bus, it is Suggested to mix blocks of data in the FLASH memory, for example, So as to be Secure from a game pirate. For example, if two or more, Such as three FLASH memories are used blocks of data may be fractured into a predetermined number, Such as two, portions and each portion written independently into different of the FLASH memories in a predetermined manner. In particular, block mixing, as it will be referred to herein, permits use of three megabytes of word-write memory using byte-wide Storage elements available from manufacturers which may be extended to four megabytes as will be described further herein. When game play is terminated or at other appropriate periods, FLASH memory may be intentionally over-written with new data or otherwise corrupted after a predetermined period of time as a further Security measure"--Asagoth (talk) 20:12, 3 November 2018 (CDT)
