#include <nitro/fs.h>void FS_Init( u32 default_dma_no );
| default_dma_no | DMA number that the ROM Archive in the file system uses. If you specify FS_DMA_NOT_USE, instead of DMA, it uses the CPU to transfer. When a valid DMA channel is specified, this DMA channel cannot be used until the setting is changed with the FS_SetDefaultDMA function.The card access transfer source is an IO register, so DMA Channel 0 cannot be specified.

None.
This function initializes the ROM file system. The following processes are performed.
CARD_Init function.
rom:/").
For more information on internal operations when allocating a DMA channel to the ROM Archive, refer to the description for the CARD_ReadRomAsync function.
When a valid DMA channel is specified, this DMA channel cannot be used until the setting is changed with the FS_SetDefaultDMA function. The file system uses this DMA channel internally to access the NITRO ROM device. Refer to the description on the CARD_ReadRom function and CARD_ReadRomAsync functions.
