Gradual Reduction in MF Effectiveness

[Jarulf]

Does this mean that column isn't actually used but that there's instead a special cubemain.txt and uniqueitems.txt file for non-ladder realms games that has all the ladder-only lines removed?

No, only one cube and unique data file is used in all cases (well, on realms a realm cube data file is used, but for both ladder and non ladder). The game simply chack game type and if the unique (or recipie) is of ladder type. For unique selection, this is the test:

:6FC4CDC0 8B4C2414 mov ecx, dword ptr [esp+14]
:6FC4CDC4 80796A00 cmp byte ptr [ecx+6A], 00
:6FC4CDC8 750B jne 6FC4CDD5
:6FC4CDCA 83797400 cmp dword ptr [ecx+74], 00000000
:6FC4CDCE 7505 jne 6FC4CDD5
:6FC4CDD0 85420C test dword ptr [edx+0C], eax
:6FC4CDD3 7552 jne 6FC4CE27

First test is the game data records info on ladder type. Next the game check for LoD and finally if nessecary to see if the unique is dropable in ladder, otherwise it is skiped.
