I just updated TetriMax, you can download it from scriptspot.
here the major change in this version :
-- no need for managed directX anymore, that mean it work under x64 now.
-- (music still don't work under x64)
-- (there may be some codec compatibility here that I'm not aware of)
-- no control over the sound volume but you can turn it on/off and adjust it throught the mixer.
-- changed default highscore to 0
The code is now free so you can play with the setting if you wish ....just keep it free please :shrug:
Hope you like it !
