As everyone knows PES works well only on 70IT and 101IT , its because of multi-touch... Archos 43 doesen't have one , thats why it didnt even install.
But i find the way to install this game. You just need to download a file ? and move him into /etc/permissions/ folder(u can do it only with root), then just install the game and download a cache...
I know many people say this is useless , because if u don't have multi-touch u can't play this game , but if u want u can use accelerometer.
sorry for my english =)
