i have just uploaded mtetrinet to the extras repository.
This is not finished yet but it already works.
I am about to make this a community thing. Anyone e.g. interested in providing a tetrinet server for the maemo community? Or e.g. a maemo theme? (mtetrinet uses the same theme format virtually any other tetrinet client uses, you can e.g. just place a new theme file in /usr/share/mtetrinet/blocks.png to use it)
Also this is based on "tetrinet for linux", a command line client. This is not 100% compatible and fails e.g. the checks on tetrinet.de. Anyone interested in making tetrinet for linux compatible with those sites? Any changes done to the original "tetrinet for linux" source code can easily be included into mtetrinet as it re-uses the original source code.
And to answer the question before it's been asked: This is not based on gtetrinet since that would have required me to port some libraries not yet available for maemo resulting in much more work than the current port of "tetrinet for linux".
I don't play this anymore, but its neat. What about performance? Is it playable or is there lag?
