Feyring have you seen the videos on how to convert vx to mv?

I have looked at some back in the day. I can take a look again but it is highly unlikely to work with my project... yeah... ok I have seen those two.
The main issue is the fact that you can't convert scripts into plugins... or at least you couldn't back then and I doubt it's possible as the two version use a different programming language.
Another problem is that the tile size in MV is larger than in VX, which isn't too big of an issue on normal projects using default chipsets, however I use almost exclusively parallax mapping which will mean I would need to redo all of my overlay layers while my ground layer will also have some alignment issues with pass-ability... if I upscale them I will likely lose quality.
I also use the "Script" command for making some basic arrays that a lot of my systems like clothing, names, etc are stored in and they probably wont translate either due to difference in programming language.
My game has too much "custom" content which is very unlikely to transfer without completely breaking.
