PSO is one of those games I don't like modding/hacking in, personally. Things like seeing enemy HP and such aren't too much of a bother, but just not for me. Full-blown hacking. Nah, I am happy without.
You are selling Heart of YN-0117 for 5PDs? Would you be willing to haggle? I have 2PDs, Grass Assassin's Sabers, Diska of Liberator, and Delsaber's Buster. Would you be willing to make this trade? Not sure how I'd get Elenor mag cell otherwise, and I kinda need it for one of my characters...
Apart from PSOBB, I've been playing a lot of Fallout Shelter on Steam, and I have been doing a "Hero of Hyrule" run on my 2DS (A Link to the Past, Oracle of Seasons, Oracle of Ages, Link's Awakening).
