Installed on my old Android Marshmallow phone fine and all working. On internal in folder IGO_Basar. Copied over to new Android Marshmallow phone to Internal storage in folder IGo_Basar, with save folder deleted and sys.txt deleted. Installed but starts and then immediately shuts down.
On first install it creates sys.txt and save folder along with licences, but app just starts and then shuts down. Reboot did not help, reinstalling did not solve issue.
Have also tried un-installing and complete new install with files from post #1, but same result.
Any way to debug what it does not like.
New phone is OnePlus3.
Suspect it must be screen resolution or driver.
Sys.txt just the one created by the app.
