Nah. Back when I got my Wii, one of the first things I did is figure out how the flash memory is divided. I'm a geek like that.
By dropping a couple files onto an SD card adn looking at them on a computer you see that 1 "block" on the Wii equals 128KB (if my memory serves me
). Multiplying that out by how many blocks are available for user access, you see that the Wii's flash is divided into two equal pieces of 256MB each. 256MB for user stuff, 256MB for system stuff. Another thing that one notices is that the emulators for VC games are packed into the ROM for the game. Looking at Mario 64 for example, you see that the VC download is 11MB. Mario 64 is an 8MB ROM in the wild, so that leaves 3MB for the emulator. It makes sense for them to do it like that really, as they can custom tailor the emulator per each ROM. This works better in the real world than a system like the PSP uses, where the PSone emulator is part of the OS. Better compatability for the particular game being sold.
