There are two types of scripts in PC RN: The "hollow mode" scripts which are the ones like Nine Bullet Revolver which have hollow ataraxia-like effects that aren't very compatible with original PC, and then the "fate mode" scripts which are the same style as original PC.
The benefit this has for the current patch is that fate mode scripts make up the vast majority and with a few easy tweaks can be inserted right into the original PC version. This way I'll be able to catch a lot more of the changes besides just BGM like new sound effects, new sprites, etc.
Note that this will not be a translation project. None of the changes in the dialogue or narration will be reflected. My hope is that if there is a translation project in the future this could give it a jump start. Though once I'm done inserting the translation I'm planning on also inserting the H-scene stuff from the original PC in to make PC RN readable in the meantime.
Also while I'm working on this I plan on uploading a patch with my current progress every week. Since this is going to be a lot of scripts I'm worried about QC, so it would be great if anyone wants to read through them and let me know about any errors.
OH also, unrelated to this I'd like to point out some patches done by other people that you guys might be interested in.
Realta Nua OP patch by MeruP
This is planned to be included in the next version of the RN conversion patch later, but MeruP would like some feedback on how it works.
Fate Stay Night Improved Uncensor Patch by Himeros and Belldandy100
Much better than the old one.
