good luck, I wish I could help you but I lack the skills to mod arcade sticks :/
in other news, Aquapazza: Aquaplus Dream Match is going to be released in USA in November 19th, published by Atlus; they've recently uploaded a
trailer (presumably one of them).
For those who don't know Aquapazza, it's a fighting game (duh :V) developed by Examu, featuring Aquaplus characters, which was originally developed for japanese arcades and later received a PS3 port for Japan; though it wasn't region locked, importing it was expensive back then (it will be released for somewhere around $30), and there *was* no expectancy for it to get a US localization, since the game features quite a lot of different series (Utawarerumono, Tears to Tiara, White Album, Comic Party, To Heart, Kizuato, Routes.. don't remember the rest). It was a surprise to me and other fans of the game, that it's actually (and finally) going to be available for the US region (more importantly, for a more affordable price).
