I find the team maverick one patch to be the best so far; the nice thing there is if you can run CFW you can use the ISO you rip from your UMD alongside a PRX plugin so you don't need to repatch the ISO every freaking time the patch is updated.
I use the most recent Team Maverick One patch (3.7), but in the latest update, they changed the names of some items to match the names on MH Tri (for the Nintendo Wii). You'll see things in your item box that you have no idea what it is. That was a bad move on their part.
I have a feeling that the people doing that patch don't use English as a first language. The grammar and syntax errors clearly point to a non-native English speaker(s). They also seem to think that the names on Tri are the 'official' translations and correct. But this ignores the past precedence (in regards to the Capcom-approved English translations) with the North American and European releases of 'Monster Hunter' (PS2), 'Monster Hunter Freedom' (PSP), 'Monster Hunter Freedom 2' (PSP), and 'Monster Hunter Freedom Unite' (PSP).
Yeah, reading some of the item descriptions is amusing, to say the least.
I prefer the Team HGG patch because, despite the fact that Team Maverick patches more of the game, most of the translated text looks like it's been sent through google translate. In other words, there are a lot of errors, many of them aren't even minor spelling issues. Any english speaking editor would rip the patch apart.
And for whatever reason, whenever I get a hostile environment monster, it always says that I failed even when I kill it, a problem I didn't have with Team HGG patch. --- "Whats more manly then enslaving creatures with your balls and then making them do your bidding." --My Cousin
