; WHO  : ItemDrop::CItemDropManager::calcRank((unsigned short, int))
; WHAT : Override the chest quality you get when the game initially decided you get no chest at all
;      : It's a bit tough to explain, but the function calcRank does this:
;      : 1) Calculate luck for gold chest, if success exit with gold quality (1), else process next step
;      : 2) Calculate luck for silver chest, if success exit with silver quality (2), else process next step
;      : 3) Calculate luck for bronze chest, if success exit with bronze quality (3), else process next step
;      : 4) No chest at all, exit with no chest (0)
;      : --> The mod below only changes this last step. So even if you put 1 value (gold chest), you'll still get a silver chest if the game succeeded the step 2.

_minDropRate = 0x00000000
0x00000000 = cmpwi r31, 100 ; this value is the default drop ratio under which we want to set a new drop ratio (logically equal or greater)
0x00000008 = blt .+0x8
0x0000000C = b .+0x8
0x00000010 = li r31, 100 ; here you set the new drop ratio
0x00000014 = cmpw r3, r31
0x00000018 = blr

0x021AF5DC = bla _minDropRate ; modify drop ratio for gold chests
0x021AF5F8 = bla _minDropRate ; modify drop ratio for silver chests
0x021AF614 = bla _minDropRate ; modify drop ratio for bronze chests
