I've been working on this project for the last couple of days. I'm trying to write a program that copies a file from the cd to the saturn's internal memory. Basically a way for people without a netlink or a PAR to get saves. My source code compiles (with 2 warnings) and boots on a real saturn. The code also executes fully, it prints out my "Done" statement at the end. Unfortunately it doesn't seem to be copying the file properly. Anyway here's my source code, I've already wasted enough blank cds

#include "sgl_cd.h" // Required for cd access
#include "sega_bup.h" // Required for backup memory functions

BUP_Init(BUP_START, workmemory, conf); // Initializes back up cart
slPrint("Back up initialized...", slLocate(1,4));
strcpy((char *)writetb.filename, "FPS_6MEN_01"); // Specifies filename for the save
strcpy((char *)writetb.comment, "Test2"); // Specifies comment for the save
writetb.language = BUP_ENGLISH; // not sure what this does?? language probably
writetb.datasize = 320; // Specifies file size, this is not working.
slPrint("Formatting internal ram....", slLocate(1, 5));
BUP_Format(0); // Clears interal memory, 0 = internal memory, 1 = backup cart
BUP_Write(0, &writetb, cdhn, 0); // This should copy the file to internal memory but doesn't...
slPrint("Done.", slLocate(1,4)); // Prints done to the screen

slSynch();
}

After I run this cd, my internal memory is wiped clean, and there's a file called FPS_6MEN_01 which is 6 blocks big. The real save should be 320ish. When I load Fire Pro, and select internal memory, I get a message which I'm assuming says, "Corrupt Save" or something to that effect. I can't read Japanese. Anyway to make a long story short this isn't working and I'm giving up. Anybody up for finishing this project? Later |
