Hi everyone, Is it normal that tetris grand master 1 is very slow in mameox128 plus ? It's not very playable. ( i use 20060505 of mameox128 plus) i mean the rom itself is 2mb so i wonder why it runs that bad...is there a specific configuration to run this well? i saw on another thread that tgm2 works pretty well if set to 4 12 65535 in the vm.txt, so it's strange that the first one runs bad here... thanks for your help
