Au contraire, mon frère! Art Anker pointed this out to us many moons ago:
[REL] Trigger Maru 1.7.6 (Updated 24Jan08)
Quoting Ducimus in that thread: "it is imperitive that it be ran on a clean installed sh4 version 1.4"
Since I cannot find it any longer on SubSim here, we'll link you to s7rikeback's link:
Trigger Maru v1.7.6
I also cannot find the ROW mod mentioned in the thread, but another thread does mention that it appears to be included in TMO v1.7.6. There is a compatible RSRDC available also, just make certain you have the correct one of those.
