Ok i've created a 3.XX game that loads, but.....Im trying to check to make sure the files are correct size etc. e.g 390.PBP

Code:

   SceUID fd;
   int size;
   
   dataPSAR = (u8 *)memalign(0x40, 0x0100a830+256);

   if (!dataPSAR)
   {
      ErrorExit(6000, "Cannot allocate memory (1).\n");
    }

   dataOut = (u8 *)memalign(0x40, 2000000);

   if (!dataOut)
   {
                 ErrorExit(6000, "Cannot allocate memory (2).\n");
    }
   
    printf("Opening and checking 390.PBP..... ");

   fd = sceIoOpen("ms0:/390.PBP", PSP_O_RDONLY, 0777);
   if (fd < 0)
   {
      ErrorExit(6000, "Cannot open file.\n");
   }

   size = sceIoLseek(fd, 0, SEEK_END);
   sceIoLseek(fd, 0, PSP_SEEK_SET);

   sceIoRead(fd, dataOut, 200);

   if (memcmp(dataOut, "\0PBP", 4) != 0)
   {
      sceIoClose(fd);
      ErrorExit(6000, "Invalid PBP file.\n");
   }
   
   size = size -  *(u32 *)&dataOut[0x24];

   sceIoLseek(fd, *(u32 *)&dataOut[0x24], PSP_SEEK_SET);

   if (size != 20314528)
   {
      ErrorExit(6000, "Invalid 3.80 update file.\n");
      sceIoClose(fd);
   }

   if (sceIoRead(fd, dataPSAR, 20314528) != 20314528)
   {
      ErrorExit(6000, "Invalid 3.80 update file (2).\n");
      sceIoClose(fd);
   }

   sceIoClose(fd);

   printf("OK\n");


That one can't allocate the memory.

Now this one doesn't get the sha1 right, i also removed the previous code.
Code:

u8 sha1_390[20] =
{

        0x19, 0xAF, 0xAC, 0x87, 0x8B, 0xD3, 0x9E, 0x7A,
        0x37, 0x4F, 0xF1, 0xCB, 0xF1, 0x0B, 0x9A, 0x1E,
        0x59, 0x08, 0x28, 0x89,
};

    SceUID fd6;
    int readx, ix;
   
    printf("390.PBP...");

   fd6 = sceIoOpen("ms0:/390.PBP", PSP_O_RDONLY, 0777);

   if (fd6 < 0)
   {
      printf("390.PBP Isn't There, Continuing\n");
   }

   sceKernelUtilsSha1BlockInit(&ctx);

   while ((readx = sceIoRead(fd6, dataOut, 2000000)) > 0)
   {
      sceKernelUtilsSha1BlockUpdate(&ctx, dataOut, readx);
   }

   sceIoClose(fd6);
   sceKernelUtilsSha1BlockResult(&ctx, sha1);

   printf("\nSHA1: ");
   for (ix = 0; ix < 20; ix++)
      printf("%02X", sha1[i]);

   if (memcmp(sha1, sha1_390, 20) != 0)
   {
      TextColor(RED);
      printf("Error\n");
      //ErrorExit(10000, "\nERROR: Invalid SHA-1. Try again.\nAuto-exiting in 10 seconds.\n");
   }

   TextColor(WHITE);

   printf("\n3.90.PBP is Correct\n");


Is it something to do with Dark_AleX's code, my codes? or 3.XX

Code:
PSP_MODULE_INFO("Check", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_USER);
PSP_HEAP_SIZE_MAX();


Heap is there

Are you sure that's the sha1 of the 3.90 update?
Because mine gives me 5957951D3F7B8A4D715C36D9135E65693F6DA334

EDIT: but the psar gives me the same sha1 than yours 19AFAC878BD39E7A374FF1CBF10B9A1E59082889, but you are reading the full file, not just the psar.
