SD cluster size incorrectly detected #7

Open RocketRobz opened 3 years ago

RocketRobz commented 3 years ago

While testing libslim in TWLMenu++, when launching a game, it says the SD cluster size isn't 32KB.

Maybe we need to manually set this..? How does TWLMenu++/nds-bootstrap determine cluster size

RocketRobz commented 2 years ago

It checks for f_bsize:

if (f_bsize < (32 << 10))

Which is configured here:

Probably need to set this so the equation balances properly, could possibly be a source of bugs with libslim
