I read that the evolution of Wurmple depends on its personality value: p mod 65536 = pw pw mod 10 < 5 then evolve to Silcoon, else evolve to Cascoon Source: http://bulbapedia.bulbagarden.net/wiki/Personality_value#Wurmple.27s_evolution I play pokemon omega ruby and I have 2 Wurmples. I looked up their personality values using pkhex. (I used Encryption Constant, because it is the 6th Generation) One with p = 0x41472683 = 1095181955, pw = p mod 65536 = 9859, pw mod 10 = 9 (should be Cascoon) The other one with p = 0xB7C26A86 = 3082971782 pw = p mod 65536 = 27270 pw mod 10 = 0 (should be Silcoon) But both Wurmples evolved to Silcoon. Any ideas how this can be? Why do both Wurmples evolve to Silcoon?? I also tried this calculation with their PIDs (allthough this only matters in the 3rd Generation), but there is the same result. One should evolve to Silcoon, the other one to Cascoon.
