I tested DM3/DM4 for the necessity of a leaderboard split from original and the Early Days Collection on SRC. I tried operating the "Emulator (Gambatte)/compatibles(GBC)", "GBP/GBI", ”Switch/PC (Early Days Collection)" at the same time, and they were almost the same speed, so won't split them.

The use of rewind functions and state load & state save is not allowed.
