This will probably seem like an obvious point to some people, but it had me going for a while - I really thought you could not get foreign commentary to work on PES6. On PES5 I always liked to use Spanish commentary, which was a lot less annoying than the awful English commentary, and actually sounded pretty cool ("GOOOOOOOOOOOOOL", etc etc). Quite a simple fix - reinstall the game, but include Spanish data. I imagine some people (like me) would think that this is unnecessary during installation, but it is only 4MB more to install and sounds infinitely better. Just go into Settings > Language in the game, select commentary language, and voila! Spanish commentary with English text. This will certainly do until the FIFA commentary patch is released, and even then it will be better to some people's ears.
