We owe tons of thanks to Gran Virt for suggesting a very simple trick which consists of altering just one dedicated byte directly in the binary of the old Critter, in order to make it compatible with Android versions which require PIE (Position Independent Executable). A truly smart catch by Gran!
Android up to 4.0.4 (API level up to 15) require NOPIE builds and don't accept PIE.
Android 4.1 to 4.4.4 (API level 16 to 19) can run both NOPIE and PIE.
Android 5.0 and up (API level 21 and up) require PIE and don't accept NOPIE.
Thus, the trick should be a tasty surprise for people with Android 5.0 and newer, who could not run Critter arm5 NOPIE until today. Now, they are provided with a legendary 3000+ ELO engine.

Let's all remember that before the arrival of Chiron 4, the old Critter build, made in 2012 (!!!) used to be the #3 engine for Android for a very long time. It deserved this trick indeed.
One would dream of arm7 and arm8 builds of Critter as well but let's not get into unrealistic phantasys. Richard Vida stopped developing Critter after R.Houdart's threats long ago and there's no hope for a comeback.
