Yuri, Falltrix pro is great with PB602. It's considerated as a gift from you.
It's hard to stop playing, My concern is about.... how to pause it ! couldn't we make a pause ? we must stop it and restart from the bigining ?
it's a minor concern.
I wish one day I could learn how to program on my own.
could it be done relatively easily?
Those 80's ish LDC handheld Vtech time&fun games and also nintendo game&watch was simples but effectives.
those Russian versions are greatly addictives too! take a look at:
