Usage

Loading Robin firmware image

The following code is used in SceWlanBt on System Software version 0.996.090. 

        ret = sceSblFwLoaderLockForDriver("os0:kd/wlanbt_robin_img_ax.skprx");
        if (ret < 0) goto fail;
        ret = sceSblFwLoaderLoadForDriver(1, 0, 0x80000, &g_fwLoadedSize);
        if (ret < 0) {
          sceSblFwLoaderUnlockForDriver();
          goto fail;
        }
        ret = sceSblFwLoaderUnlockForDriver();
        if (ret < 0) goto fail;
        g_isWlanbtRobinImgAxLoaded = 1;

Loading PSPEmu firmware images

See SceCompat#sceCompatPrepareLoad, SceCompat#sceCompatInit and SceCompat#sceCompatInitEx for PCBC and PCFF loading.
