Access line Memory 64 is a 256kb pak. The pak is very reliable and doesnt look like
a cheap product. The Memory chip is produced by Winboard. The price is $12 which makes
it a bit cheaper than the official Nintendo Pak. The only disadvantage of this pak is
that its only 256kb, which means that it quickly gets filled up.
Performance Memory Card Plus is another unofficial pak by InterAct Accessories. It's a 1mb pak
which is devided in 4 x 256kb (has a switch on the back). The size of the pak means that it
can hold a lot of savegames, even if you've got some of the big ones, like Snoboard Kids which
requires 123 pages (256kb). But I've had problems with this controller pak. I made a International
Superstar Soccer savegame quite awhile ago which I wanted to delete, but I was unable to. The
savegame is still there, which means unit 4 is unavailable. I could ofcourse remove the battery, but
then I would loose my other saves.
