I'm clearly to stupid to get this working

In the above I mix GC40 with PC40 my bad. Wants to play MPC40
I have played "MPC37-39", and its relay fun, so like to play
MPC40, but how? The way I got "MPC37-3" working was unRAR "
MPC '37-'39_08-08-13" into MODS folder, and using JSGME, no problem works nicely.
BUT how to import my old Core into "
MPC '40 v0.1". I have "
MPC '40_16-08-13" as a RAR file and also GC installed? Used the method for "
MPC '37-'39", that is unRAR "
MPC '40" into MODS folder, and using JSGME, no problem works nicely. "
MPC '40" starts up BUT not with my core. Sub title "From the northern abyss to Damocles"
