Monster Hunter Freedom 2

[Gamez1985]

Sorry for asking such a noobish question (everyone has to start somewhere) but, what device or homebrew program utilizes these codes? I am very new to the homebrew scene and am currently waiting on my PSP to be modded by the Johnny guy at this site. I loved MH:F1 and now my wife and all my friends play MH:F2. Not being able to trade all the items kinda blows, so these codes could really spice things up. Any reply (that's on topic, lol) would be appreciated, thanks!

OH and does the Show Monster HP code work by the "just add 0's to the end" fix? AAAAND could someone please create a "Trade Any Item Regardless of Rarity" code? I really don't want to cheat for items, just edit the game to make it better. Thank you.
