So, do you want your FBA SDL to show screenshots? You want it to look like this?
Look no more!
Download the screenshot pack from here: https://ufile.io/cinyxflo
Unzip it to the .fba/previews folder of your device
Enjoy your newly pimped FBA SDL!
Warning! Having screenshots will increase the loading time of the emulator!
Please note that I have just rotated, resized and edited the images to fill the fully screenshot area. The original images are not done by me, and I don't remember where I got them from.
