If I'm not mistaken, it was removed from the Android market several months ago. You can still find the apk out there on the net or in the torrent community but then you do run the risk of not really knowning where the file comes from. Just use your Google-fu. It's not that hard to find.
google-fu has nothing to do with this one. I've been on google for 2 days straight now.. This app does not exist anymore. It was banned due to breaking developer rules somehow so the people who made it and all of their apps have been removed from everything. it started out as just android market then led into everywhere else. There is one that you can get, but your phone has to be rooted to do so. It's called Gamecih 2. the old one gamecih is on the market but it has the link to get the newest one.
