Installed new arcade hack, seems to be the better one. And installed like 400 new games, still got about 500 to go, can't do it any more, I'll continue some other time.
Please report any double games, I imported old games and installed new ones, so there will be some of them appearing more times, I couldn't check everything, so please reply here with the name of the game so I can remove it.
Imported old high scores too.
Thanks to DeeJay Dan for posting his pack of games, 700mb in size.
To see all new games just sort them by Date added in descending order.
