I meant, to skip the grind as in having all resources or all items crafted
You can cheat resources with cheat engine.
All items?
You need to GRIND, due to "% chance" of 1 out of X items drop on bosses that are strong and made for "upgraded" gear that isn't implemented.
You can win [you can also lock HP in cheat engine, but you need to find it in middle of the fight and another battle will require you to start searching again].
Also each "fight" consumes points [2 per 1 battle attempt].
You can cheat it by editing bloated save file with hex editor [one value somewhere in middle, second somewhere near the end]...
Let's not forget that forgetting to unlock value can lead to the crash.
