Also, are you guaranteed a set number of drops at the end of a run? Maybe that number needs to be subtracted out or added to the number you're searching for.
Yes and no: over the course of a run you'll fight enemies and find chests you can open, they'll always contain 1 random item ranked E-S.
Killing a boss rewards you with 1-N drops, as if they were obtained from a chest.
For example at the end of LoC's 2nd floor killing the boss gave me 3x A-rank loot and 1x S-rank loot.
Afterwards you'll see a screen asking whether you want to continue or go back to town, plus listing how many drops of each rank you got, these account for the boss loot.
Just tested your Dragon's Crown code for the US version of Dragon's Crown(PCSE00019) and they work flawlessly so I guess I can still help with anything if you need. I only tested the Max score and the All Common Skills so far. I can't for the life of me remember what Talismans are or were used for so I couldn't really test those, its been awhile since I last played DC. The max score code got me from level 1 to lvl 35 in 1 run although, this game still gives me that Skill Point problem of resetting your skill points when gaining too many. Out of 35 levels, the game only gave me 2 Skill Points when I got back to town so some kind of anti cheat measure must be in place even when gaining too many levels.
-Edit
After some more further testing, it looks like the Common Skills codes isn't permanent and needs to be either reapplied after a dungeon run or left on. I think it was like this for the old DC codes wasn't it?
Sick, 2:1!
Yes, all the skills codes need to be re applied every time, the same is true if you add infinite skill points.
Talismans are used to unlock the fight against the ancient dragon, which unlocks the next difficulty and gives you 9 S-rank drops, they're useful when levelling alts.
You can see which talismans you have unlocked by pressing start while in town and looking at the bottom left portion of the screen, they're shown above the runes you unlocked.
If you can get a memory dump in which you have some talismans in normal/hard/infernal and ultimate difficulties that may be enough for me to find the address.
Ideally unlock 1-3 talismans for normal/hard/infernal.
Then unlock 2-3 talismans in ultimate and dump the memory after each one, that should be the enough to find the address.
