Whodares' routine will indeed happily load a file into RAM but never return a pointer or anything to the data

lol, good call, I never even noticed that :-P

Updated it now.

Whodares' routine will indeed happily load a file into RAM but never return a pointer or anything to the data. (add return myBuffer to the end of the function). Also, dont forget to free() your buffers when you're done with them.

Determining file size is simple enough as long as you're not working with streams that you can't seek in (on Wii, you're almost certainly not):

int pos = ftell(File);
fseek(File, 0, SEEK_END);
size = ftell(File);
fseek(File, pos, SEEK_SET); //return to previous position

void* loadFileContents( char* fileName, int fileLength )
{
	void* myBuffer;
	FILE* inputFile;

	inputFile = fopen( fileName, "rb");
	myBuffer = malloc(fileLength);
	fread( myBuffer, 1, fileLength, inputFile);
	fclose(inputFile);
	return myBuffer;
}

I can't remember the code to find the file length, but something like this will dynamically read the file in. Don't forget to deallocate the space after you're finished :-)

What, loading a file in ram ? You're speaking about load a file into a variable ?
If yes, use fread(); =)

I'm trying get a program I'm creating to load a file into ram. Now I'm not sure if LibFat or the memcpy call does this so can someone explain to me with some example code how to load a file into ram.

also can someone tell me how much ram the wii has, I looked it up on google but everything I found says different.
