Monster Hunter Portable 3rd HD

[RzLaunch]

Well, both of your suggestion are valid AND I have already done both btw. I was using the general store unlock all to get materials until I completed zinogre set after finishing it's urgent quest, but then I realized that it spoiled too much of the game especially when compared to when I played MHFU with inv.carve cheat. So now I didn't use any cheats, but now it's such a pain trying to collect materials for just a set of armor.
Furthermore, not all materials can be obtained just by carving, there are some mats that needs you to break, capture, or use tools like pickaxe. So I don't think inv. carving is spoiling the game as much as unlock shop.

tl;dr - I need that inv. carving cheat, badly.

And for monster record sizes, just use lunamoo's CE cheat table, rather than using the cheat you wanted and then fighting the monsters again, it saves time and the result are the same.
