Hi Sega.
Congratulations for the mod and the great effort put into it.
I am very curious to know how you have managed to get the characters from outside the party to win all the experience. I have fiddled with programs like PrC, WM or Makou Reactor, among others and I don't know how it could be done.
It's done through the executable as an assembly calculation:
#Passive EXP Modifier (if .exe is dormant/hard-patching the .EXE with an installer)
#1C6301 = 90 90
#Nops the calculation, resulting in 100% passive EXP
#Passive EXP Modifier (if .exe is active/hext injection is being used such as 7th heaven or reunion)
#5C6F01 = 90 90
#Nops the calculation, resulting in 100% passive EXP
I think I removed this from the 1.5 version of the mod at some point and I don't think it ever made it into the 2.0 version. I guess I preferred to swap characters in and out based on their level as they overtook each other. I think this offset was found by either DLPB or NFITC1, I forget where I found it (maybe in an old buried post; I did a few dives into the old threads of this forum years and years ago looking for bits and pieces).
But in any case, that's the offset that deals with it.
