i made some NullpoMino rule files for people looking to practice 20G, to save them from having to screw with the rule editor themselves http://www.petedeas.co.uk/tetris/Classic1Slow.rul http://www.petedeas.co.uk/tetris/Classic2Slow.rul put them in NullpoMino's config/rule/ folder, select CLASSIC1-SLOW or CLASSIC2-SLOW in OPTIONS -> RULE SELECT 1P, and play a game with [CURRENT RULE] instead of the suggested defaults. use Hold to get a new piece when you're ready for one. the only modifications from the non-slow equivalents are to have 9999 ARE and ARE cancel on hold
