Nothing to check for me. I don't support vmos (actually, I don't even know why need vmos), so I can't tell if any of my mods ever work in vmos. I tested this mod directly installing on A20 or A11 phones without vmos, there working ok (, hmm probably still need to check A11 cause I didn't borrow that A11 phone for 2 weeks already)
If you see any other drops spitting 57x then it means the mod works. It might not work on whatever medal that you mentioned, that's something I can check later. Other players probably can help me confirm if it is working or not since I don't play this game whatsoever. In fact, a few players here would be super expert in this mod and know what works or not, since they play the mod/game since day 1.
Anyway, no need to compare my mod against other modders. You're free to use whichever mods that work for you.
I appreciate feedback though, if there is something really not working then I can try to fix that (when I get chance, lately I had been super busy).
Anyway, will check why medal not doing 57x there in about 8 hours time when I get home.
