what was the intention of limiting the GOY to 8Mbit only? Looking at todays flash prices even a 100 time of that storage wouldn't have had much influences on its end price.
There were a lot of reasons for making the basic 8Mbit card: low power, low cost, no menus, low parts count (needed to keep the card size to a standard HuCard size).
Like thesteve said, there is no need for mapping logic. But also, you will be very hard pressed to find a larger parallel flash memory device than what I'm using, which uses a 5v supply. So then you would have to look into level translators or using multiple flash chips.
I wanted to make something that would use the minimum amount of parts, and have a low price point.
By the way, I have made some more cards, & hopefully I will be able to keep up with orders now, so that I can keep the checkout basket open from here on.
