Hi !
Does anyone know how to remove a *.prx file into flash0:/vsh/module directory.
until 3.71m33 this directory is Hidden and in ReadOnly mode
I just want to be able to delete/replace some files in this folder but... that's doesn't work.
ex:
I juste make a dummy.txt file inside vsh/module via Windows
With sceIoRemove I can't remove this file...
sceIoRemove return no error ...
Any idea ? flash0 is already assigned with 0777 attribut
it's possible to replace vshmain.prx and paf.prx via an eboot in kernel mode ?
How to change vsh/module attibut
thanks but that's doesn't work...
so I can't remove or replace file in flash0:/vsh/module directory
sceIoRemove("flash0:/vsh/module/paf.prx")
sceIoOpen('flash0:/vsh/module/paf.prx", PSP_O_RDONLY, 0777);
return error...
So if I can't remove or open it's impossible to me to write a new one.
I just want to finish a Theme Flasher who can flash paf.prx and vshmain.prx
So if I want to copy a dummy file in flash0:/vsh/module/ dummy file go in vsh/podule ! WTF ?
i'm in PSP1004 FAT 3.80M33-5 with Kernel 1.50
so I can't remove or replace file in flash0:/vsh/module directory
sceIoRemove("flash0:/vsh/module/paf.prx")
sceIoOpen('flash0:/vsh/module/paf.prx", PSP_O_RDONLY, 0777);
return error...

... *cry*
ok I just try to make a fonction
but
return "File not found or Already Deleted"
I've try without the file_exist test but same way... the PRX was not deleted...
any idea ?
ok I just try to make a fonction
Code: Select all
void Remove_file(char * Delfile)
{
int file_exist,test_del;;
file_exist = sceIoOpen(Delfile, PSP_O_RDONLY, 0777);
if (file_exist>=0){
SceIoStat stat;
memset(&stat, 0, sizeof(SceIoStat));
sceIoGetstat(Delfile, &stat);
stat.st_attr &= ~0x0F;
sceIoChstat(Delfile, &stat, 3);
test_del = sceIoRemove(Delfile);
if (test_del<0){
pspDebugScreenSetTextColor(0x000000FF);
printf("%s - Cannot delete file\n", Delfile);
}
else {
pspDebugScreenSetTextColor(0x0000FF00);
printf("%s - File Deleted OK\n", Delfile);
}
}
else {
pspDebugScreenSetTextColor(0x00303030);
printf("%s - File not found or already Deleted\n", Delfile);
}
}Code: Select all
Remove_file("flash0:/vsh/module/vshmain.prx");
Remove_file("flash0:/vsh/module/paf.prx");I've try without the file_exist test but same way... the PRX was not deleted...
any idea ?
This works for me...
Code: Select all
SceIoStat stats;
sceIoChstat( file_path, &stats, 0x0003);
sceIoRemove(file_path);
just try with
but ...
flash0:/vsh/module/vshmain.prx - Cannot delete file...
Code: Select all
void Remove_file(char * Delfile)
{
int test_del;;
SceIoStat stat;
sceIoChstat(Delfile, &stat, 0x0003);
test_del = sceIoRemove(Delfile);
if (test_del<0){
pspDebugScreenSetTextColor(0x000000FF);
printf("%s - Cannot delete file\n", Delfile);
}
else {
pspDebugScreenSetTextColor(0x0000FF00);
printf("%s - File Deleted OK\n", Delfile);
}
}flash0:/vsh/module/vshmain.prx - Cannot delete file...
Flash0 is unassign and re-assigned without error
and i'm in
tested in 0x0800 too
Code: Select all
if (sceIoUnassign("flash0:") < 0)
printf("F0unassign: Error | ");
if (sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0) < 0)
{
printf("F0assign: Error\n");
}Code: Select all
PSP_MODULE_INFO("flash", 0x1000, 1, 1);
PSP_MAIN_THREAD_ATTR(0);This is what I have,
Also using the code I posted before seems to work fine and has been tested on 3.80m33-x and 3.90m33-x
Code: Select all
PSP_MODULE_INFO("Write2Flash380", 0x800, 1, 1);
PSP_MAIN_THREAD_ATTR(0);
PSP_HEAP_SIZE_MAX();
i hav by-pass this fonction.
Eboot not check if file exist, just check if file sceIoRemove return no error.
i'll try to install 3.90M33 ... sniff i love my 3.80...
[edit]
Same way in 3.90M33-2 k1.50v2

I just did a few tests with the code and it seems I'm also now getting strange results,
I created 4 read only txt files and tried to delete one and it would not delete until I tried to delete the 2nd time,
But I can then delete any of the other read only files in one go,
Seems strange to me so I will try to work it out,
