Wii Memory Block Question(s)

[SJGohan3972]

Exactly how much space in terms of bytes is a memory block defined as in the Wii's OS?

 

I only ask because my 2 GB SD card came up at just under 15,500 memory blocks (its not a round number and I forgot it).

So taking it off those numbers (however vague they are) that puts 1 GB at just under 8000 memory blocks (7750) and 1 MB at around 7.75-8 memory blocks.

 

Now I may be imagining things but I seem to remember that Nintendo was supposed to have set a limit at how big WiiWare games should be, but I was just now moving some WiiWare games to my SD card and saw that Space Invaders Get Even is 307 blocks.

Now I know my math isn't very close (infact the impreciseness of it is quite annoying to me but I will battle onward)
but by my calculations that comes out to about 38MB for the game. Is it just me or is this a little big? I could be underestimating the size these games should be but the art style games were each between 50 and 150 blocks (6-19 MB or so)

 

Just wanted to ask if anyone knows anything more on this, thanks.
