Just wanted to post some cheats (because the game gets a little tedious towards the end) and a glitch. I hope you don't patch these out because they are useful.
To change values like gold and current rank, open the Registry Editor and go to:
Computer\HKEY_CURRENT_USER\SOFTWARE\SheableSoft\Seleka-san who Exposes unnoticed with Naked Coat
Important values:
CurrentRank - player's rank, ranges 0-7 (7 unlocks Invincible mode)
Gold - money to unlock clothes
totalRankPoint - total points acquired, 3000+ unlocks last rank and Invincible mode
Current rank = more stripping, 7 = unlocked invincible mode
Also current rank corresponds to heart rate!
0 = max heart but only flash front (no butt/shoulders/take off)
3 = shoulders, still gets up to 150bpm
5 = take off coat, can get up to 150
7 = least heart rate
I did 8, and her heart rate hovered around 99, wouldn't go up, and she had that sad face, even when flashing
I did 0xFFFFFFFF (integer overflow), and I can't even access the first stage: "Unlocked at Amateur rank"
Also if you complete a stage, it resets your current rank to whatever your totalRankPoint is.
I found a glitch where you can be invincible and a lower rank (I wanted higher heartrate with invincibility):
I started at level 7 in the park, did an invincible night, then Alt+F4.
I reopened at level 3, went right into park, and I was invincible. If you Alt+F4 instead of leaving the location you will be invincible every time you reopen the game.
It doesn't do invincibility on other maps like the store, and I haven't reset it to try.
