The other way is to download LJ source code, make it run slower than 60 playfield updates per second, recompile, and record, then play back on vanilla LJ. You could change the install_int_ex() to set a rate of 300 ticks per minute instead of 3600, or you could change ljplay.c to go through the frame() loop only when the otherwise used "item" key is pressed.
