Quoted from oga83:

The 1.30 firmware is bigger than 4Gb. The game can only read FAT32 usb sticks and such a big file can't be used.
That's the reason why it is splitted in 2 files by Stern (.000 and .001).
When Pinball Browser opens these files, it extracts the .spk file in which your changes will be saved (songs, images, ...).
However, you can't use this .spk file to upgrade your game (because it's bigger than 4Gb) : You have to convert it back to .000 and .001 files.
To do this, use the "Pack firmware for USB stick" (click on the arrow on the right of the Open button). This can't be done automatically because it takes time.
Copy the .000 and .001 file on your USB stick and upgrade the game with them.

In brief :
- Open the .000 file with Pinball Browser
- Work on the .spk file
- Once you're done, use the "Pack firmware for USB stick"
- Upgrade your game with the new .000 and .001 files.

As explained in the FAQ, instead of using the .000/.001/.spk files, it is better to work on a game SD card image.

1 - The prefered method : Open an image (.img) of the game SD card :
* For Pinball Browser v6 :
Just insert the game SD-card into your PC and use the "Read image from X:"; Pinball Browser will make an image of your SD card and save it on your hard disk.
Modify what you want in this image. Once it's done, the modified image must be written to a SD-card, not a thumbdrive.
Do not use the original SD-card (keep it as a backup); use a new SD-card; no need to format it.
Use the "Write to SD" function in the SmartDmd tab.
