Excellent! Glad you're going!
Now, if you're doing multiple mods, you might be interested into looking into using
MultiSH4 v1.5 to help you manage multiple SH4 game save folders. Another helpful utility is
Rockin Robbins' SH4CMS, which can help with easy recovery in the event that things go wrong. The only problem with it is having to follow the batch files' naming convention, but if you're into editing batch files, it's no biggie.
Happy hunting!
