# SummerLoader64
A N64 bootloader for SummerCart64. This project is mainly based on work by **`jago85`** contained in [Brutzelkarte_Bootloader repository](https://github.com/jago85/Brutzelkarte_Bootloader) with some modifications that made code a little bit more readable.

----------------------------------------------------------------------------
R0.00 (February 26, 2006)
Prototype.
R0.01 (April 29, 2006)
The first release.
R0.02 (June 01, 2006)
Added FAT12 support.
Removed unbuffered mode.
Fixed a problem on small (<32M) partition.
R0.02a (June 10, 2006)
Added a configuration option (_FS_MINIMUM).
R0.03 (September 22, 2006)
Added f_rename().
Changed option _FS_MINIMUM to _FS_MINIMIZE.
R0.03a (December 11, 2006)
Improved cluster scan algorithm to write files fast.
Fixed f_mkdir() creates incorrect directory on FAT32.
R0.04 (February 04, 2007)
Added f_mkfs().
Supported multiple drive system.
Changed some interfaces for multiple drive system.
Changed f_mountdrv() to f_mount().
R0.04a (April 01, 2007)
Supported multiple partitions on a physical drive.
Added a capability of extending file size to f_lseek().
Added minimization level 3.
Fixed an endian sensitive code in f_mkfs().
R0.04b (May 05, 2007)
Added a configuration option _USE_NTFLAG.
Added FSINFO support.
Fixed DBCS name can result FR_INVALID_NAME.
Fixed short seek (<= csize) collapses the file object.
R0.05 (August 25, 2007)
Changed arguments of f_read(), f_write() and f_mkfs().
Fixed f_mkfs() on FAT32 creates incorrect FSINFO.
Fixed f_mkdir() on FAT32 creates incorrect directory.
R0.05a (February 03, 2008)
Added f_truncate() and f_utime().
Fixed off by one error at FAT sub-type determination.
Fixed btr in f_read() can be mistruncated.
Fixed cached sector is not flushed when create and close without write.
R0.06 (April 01, 2008)
Added fputc(), fputs(), fprintf() and fgets().
Improved performance of f_lseek() on moving to the same or following cluster.
R0.07 (April 01, 2009)
Merged Tiny-FatFs as a configuration option. (_FS_TINY)
Added long file name feature. (_USE_LFN)

FatFs Module Source Files R0.14a
FILES
00readme.txt This file.
00history.txt Revision history.
ff.c FatFs module.
ffconf.h Configuration file of FatFs module.
ff.h Common include file for FatFs and application module.
diskio.h Common include file for FatFs and disk I/O module.
diskio.c An example of glue function to attach existing disk I/O module to FatFs.
ffunicode.c Optional Unicode utility functions.
ffsystem.c An example of optional O/S related functions.
Low level disk I/O module is not included in this archive because the FatFs
module is only a generic file system layer and it does not depend on any specific
storage device. You need to provide a low level disk I/O module written to
control the storage device that attached to the target system.
