I decided to create a quick guide and place to share your custom BlueStacks boot animations.
The boot or loading screen is made up of two different files. One is a static PNG image the other is a GIF animation. Both files are found in C:/ > Program Files (x86) > BlueStacks and can be replaced.
Step one: Quit BlueStacks and use task manager to ensure there are no BlueStacks processes running.
Step two: Go to the directory above and copy and paste the files "ProductLogo" and "loading" to a convenient location to back them up.
Step three: Search the internet for fun new replacement files and edit as needed (or create your own).
Step four: Rename the files to reflect the original file's name and place them in the BlueStacks folder.
*restart BlueStacks and enjoy*
The animation (Dysgenic (Modified by aph)) and image (tenet421 ) I am using currently:
Edit: Thanks to rocketero,
We have a new home button image.
Go to C:>Program Files (x86)>BlueStacks and use the same process as above. The image will be called "HomeButton".
If you have another cool button post it here.
