SD cluster size incorrectly detected

[RocketRobz]

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

relevant lines:

libslim/libslim/source/ff.c

Line 125 in 4d1b958

#define BPB_SecPerClus 13 /* Cluster size [sector] (BYTE) */

libslim/libslim/source/elm.c

Line 627 in 4d1b958

buf->f_bfree = nclust * fat->csize;

libslim/libslim/source/ff.c

Line 1200 in 4d1b958

return fs->database + (LBA_t)fs->csize * clst; /* Start sector number of the cluster */

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

[RocketRobz]

It checks for f_bsize:

if (f_bsize < (32 << 10))

Which is configured here:

libslim/libslim/source/elm.c

Line 57 in 4d1b958

#define ELM_SS(fs) ((fs)->ssize)

libslim/libslim/source/elm.c

Line 623 in 4d1b958

buf->f_bsize = ELM_SS(fat);

libslim/libslim/source/ffconf.h

Line 201 in 4d1b958

#define FF_MAX_SS 512

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