Usually you'd enter the exact values of gold in Cheat Engine, but for this game it's a bit harder. I instead started off with "undefined initial value" and then would only search for value increases or decreases but without a specific amount (so Value Increased instead of Value Increased By X). Do this enough times and you will get a single result by the end of it, then enter random numbers and check by how much the gold value changes. I landed on like 900k and kept it for instance.
What I did was wait until the gold you get at the end of the round came up; 119 is a lot less values than 1 or 2. Wait until the end of next round, click "start next scan" with the gold values (BEFORE YOU ACCEPT IT), and scan for the next amount. It only took me two rounds to find the exact value. Give yourself 1,000,000 gold and that should be more than enough to buy everything in the Dark Shop and have zero issue for the rest of the game (if you still want to play, and not just buy all the CGs).
I don't know if this value is the same across different games/users, or even play throughs, but the corruption value that worked for me (actual, not displayed) was 20EA279BD68. Set it to>50 and you should get the corrupted scenes. Note that not all of them have a corruption variant, so it's possible you will still get "normal" variant for some scenes.
As to the remarks on starting weapon, yeah the mage's and ninja's definitely start off weak, but level it up a few times and the mage's is by far the best weapon in the game. It's a machine gun auto-lock weapon that you can just cut through bosses with.
That + random-area of affect + circling diamond things turns her into an AFK machine. The secret is the doll which adds +1 to every projectile weapon in the game, which the mage's starting weapon counts as, plus most of the AoE weapons count as.
Playstyle: Mage > Ninja > Swordsman
Outfits / CG: Ninja > Mage > Swordsman
Honestly neither the game nor the CGs are worth it, to any lurkers.
I appreciate the effort the translator though put in of course.
