- I'd be surprised if there were any such legal back-up systems being sold at
- a decent price. I don't know, but I'd be surprised.
-
- Remember that cart data is already compressed to a huge degree. Most
- games are 8 megabits or less so should fit on one floppy 9 times out of 10,
- and that's assuming they use low-density 1 meg disks. There are some 16
- megabit games (2 megs) so that might require more than one disk, or would
- require the back-up system to have a Hi-D or Super-Hi-D floppy.
-
- As I understand it, the maximum amount of addressable ROM space on the
- Genesis is 8 megabits (one meg). The maximum on the SNES is 4 megabits.
- To get more, they separate the game into multiple banks or 8 or 4 Mbits and
- swap between them as necessary. It seems conceivable that the back-up
- system could be designed to put one bank per floppy therefore letting a
- multi-disk system work fairly well. Most multi-bank games, I'd imagine,
- are designed to try to work sequentially through each bank of memory in the
- cart so swapping wouldn't be too bad. Personally I don't, nor do I plan
- to, own a Genesis or a SNES so I couldn't really care anyway. This
- information is as I understand it based on what I've read in console mags,
- and console mags are famous for oversimplifying things or even printing
- blatantly false info so this could very well be wrong, but it makes sense
- to me however so I do trust it.
