As you probably know, there is a new shiny loader, “Kraken” by @bl_ackrain. That makes possible to use e.g. nice loading screens, screenshots and icons for applications in SD. For that you have to convert the bin file to a pop file, which contains the pictures etc. Without a pop file your game will be shown with a generic icon and no screenshots are visible in the next Pokitto Game Disk release.
Here are the instructions: [Wiki]POP files
Here is how you can take the new loader into use in your SD card: [Loader] Kraken [new version]
Put the pop file in the existing “[Game]” topic for the game. Keep the bin file there also.
Do not hesitate to ask if you have problems with creating a pop file with a makepop tool!
