Oh my god I can't believe this actually worked. There's still a ton of small issues to resolve (mostly clipping / animations, some seams I forgot to close etc, and I haven't figured out the boss battle ink color yet. Also he makes cut-scenes lag so bad even though his file is very close in size with Frye's...) but it... works!!!
I wanted to do all of C-Side but that's gonna have to be indefinitely postponed due to me being insanely busy.
Feel free to ask any questions since I know that modding tends to be very niche and it's hard to discover information around it!
