Now, I'm not sure about either of these links as being the "best" version, or if there is a "patch" file for either one. They are liable to be the same thing, but here on SubSim is
Trigger Maru v1.7
on the nexus mods site (I have no idea as to whether their files can be trusted) is:
Trigger Maru v1.7.6
You will also find a v1.7 "patch" file, but it says it's for SH4 v1.5, hence my confusion over all of this. A feller who would know would be aanker, or cdrsubron7...
