Perhaps it's not relevant, but why is it that TXTRs always come out upside-down when dumped/converted? A quirk of the format, or a quirk of Retro's? Bearborg (talk) 09:16, 23 January 2015 (CST)

- As far as I'm aware, it's just TXTR/Retro games. Every non-Retro game I know of has right-side-up textures when dumped through Dolphin. Bearborg (talk) 09:25, 23 January 2015 (CST)
