Seklth 已开发出 MMC卡菜单里增加“复制”菜单补丁，即文件复制功能，发表在其集成版里。
如下为源码，请移植！
（好像是要改“使用提示”为“复制”）
In menu:
dw sof(_menu_move), seg(_menu_move) ;"Move"
dw sof(_menu_rename), seg(_menu_rename);"Rename" dw sof(_menu_copy), seg(_menu_copy)
_menu_move:
extp #pag(_CopyFlag),#1
mov pof(_CopyFlag), ZEROS ;std
jmps 0D8h,0786Ah ;Move dialog
_menu_rename:
extp #pag(_CopyFlag),#1
mov pof(_CopyFlag), ZEROS ;std
jmps 0D8h,07BD0h ;Rename
_menu_copy:
extp #pag(_CopyFlag),#1
mov pof(_CopyFlag), ONES
jmps 0D8h,0786Ah ;Move dialog
patch:
PATCHRENAME SECTION CODE WORD AT 0E4A9D2h ;rename call patch
PROCRENAME PROC
calls _My_Rename
PROCRENAME ENDP
PATCHRENAME ENDS
source on c:以下是C语言的Code:
int My_Rename(char far* source, char far* dest)
{
char far* buff;
int fs, fd, sz;
if (!CopyFlag) return(Rename(source,dest));
fs=FileOpen(source,_O_RDONLY,0);
if (fs==-1) return(0);//Error
fd=FileOpen(dest,_O_CREAT+_O_WRONLY+_O_TRUNC,_S_IREAD);
if (fd==-1) { FileClose(fs); return(0); }//Error
buff=EX_heap_malloc_with_lock(0x2000);
if (buff==0) { FileClose(fs); FileClose(fd); return(0); }//Error
do {
sz=FileRead(fs,buff,0x2000); //8kb buff
FileWrite(fd,buff,sz);
} while (sz!=0);
FileClose(fs);
FileClose(fd);
EX_heap_free_with_lock(buff);
return(1); //Success
}
上面是C语言的，这里是ASM的源码，可用sfe：

@EQUP(_EX_heap_free_with_lock,0D7D3B0h)

extern int FileRead(int handle,void far *buf, int bnum);
extern int FileWrite(int handle,void far *buf, int bnum);
extern int FileClose(int handle);

复制程序补丁如下：
(MMC菜单里可能要改某个选项的call为调用这个复制功能, 因为原补丁的菜单补丁很复杂，可能移植不了。比如，将“使用提示”改为“复制”)
