A Quick question... Has anyone here had any experience with coding for the 3in1?
I am trying to use the following code to backup and restore the sram, but when I start the actual gba games, I am told that the saves are corrupt.
As far as I know, the games are supposed to use sram, so it shouldn't be causing a problem from that angle.

Anyone able to help?

CODEvoid writeSRAMToFile(char* filename)
{

ÂÂÂÂu8 pages = 0;

ÂÂÂÂFILE* saver = fopen(filename, "rb+");

ÂÂÂÂu8* buf = (u8*)malloc(sramBufferSize);

ÂÂÂÂint i = 0; // the setup for which page to start dumping from if it is a prototype
ÂÂÂÂ
ÂÂ pages = TOT_SRAM_PAGES;

ÂÂÂÂOpenNorWrite();
ÂÂÂÂfor (; i < pages; i ++)
ÂÂÂÂ{
ÂÂÂÂÂÂÂÂmemset(buf, 0, sramBufferSize);
ÂÂÂÂÂÂÂÂSetRampage(i);
ÂÂÂÂÂÂÂÂReadSram(0x0A000000, buf, sramBufferSize);
ÂÂÂÂÂÂÂÂfwrite(buf, sramBufferSize, 1, saver);
ÂÂÂÂ}

ÂÂÂÂfree(buf);
ÂÂÂÂfclose(saver);
ÂÂÂÂSetRampage(0);

ÂÂÂÂCloseNorWrite();
}

void writeFileToSRAM(char* filename)
{

ÂÂÂÂFILE* saveFile = fopen(filename, "rb");
ÂÂ
ÂÂÂÂu8* saveBuf;
ÂÂÂÂsaveBuf = (u8*)malloc(sramBufferSize);

ÂÂÂÂblankSRAM((64+256)/4);

ÂÂÂÂint ret = 1;
ÂÂÂÂÂÂ
ÂÂ int i = 16;
ÂÂÂÂfor (i = getStartpage(); i < MAX_SRAM_PAGES && ret == 1; i ++)
ÂÂÂÂ{
ÂÂÂÂÂÂÂÂmemset(saveBuf, 0, sramBufferSize);
ÂÂÂÂÂÂÂÂSetRampage(i);
ÂÂÂÂÂÂÂÂret = fread(saveBuf, sramBufferSize, 1, saveFile);
ÂÂÂÂÂÂÂÂif (ret == 1) WriteSram(0x0A000000, (u8*)saveBuf, sramBufferSize);
ÂÂÂÂ}

ÂÂÂÂfclose(saveFile);
ÂÂÂÂfree(saveBuf);
ÂÂÂÂSetRampage(0);

}

void writeSAV(void) {

ÂÂ PA_OutputText(0,0,ln,"Backing up save file.\n"); ln++;
ÂÂ
ÂÂ char* saveLocation = calloc(1, 512);
ÂÂ FILE* configFile;
ÂÂ FILE* saveTest;
ÂÂ
ÂÂ configFile = fopen("/gba.cfg", "a");
ÂÂ fclose(configFile);
ÂÂ configFile = fopen("/gba.cfg", "r");
ÂÂ fgets(saveLocation, 512, configFile);
ÂÂ fclose(configFile);
ÂÂ saveTest = fopen(saveLocation, "w");
ÂÂ if(saveTest){
ÂÂÂÂÂÂfclose(saveTest);
ÂÂÂÂÂÂwriteSRAMToFile(saveLocation);
ÂÂ }
ÂÂ
ÂÂ free(saveLocation);
ÂÂ
}


void readSAV(void) {

ÂÂ PA_OutputText(0,0,ln,"Writing save file.\n"); ln++;

ÂÂ char savename[256] = "";
ÂÂ FILE* saveConfig;
ÂÂ
ÂÂ strncpy(savename, GBA_Game, strlen(GBA_Game)-3);
ÂÂ strcat(savename, "sav");

ÂÂ PA_OutputText(0,0,ln,"copying %s", savename); ln++;
ÂÂ writeFileToSRAM(savename);ÂÂ

ÂÂ saveConfig = fopen("/gba.cfg", "wb");
ÂÂ fwrite(savename, strlen(savename), 1, saveConfig);
ÂÂ
ÂÂ fclose(saveConfig);
ÂÂ
}

 

I'm not sure that information is any help to me. The problem I'm having, is that the games say that teh data is corrupt when it is loaded to the card.
