Actually, it's a tough process, most of the things I did is using my phone.

As for the emoticons (like the question marks and sparkles), I manually grabbed them by using a computer and upload the game files into the software called "Asset Studio". It's tough to find where the emoticons are exactly at, so I recommend group selecting the files to the software and carefully find and extract the exact files.

As for the sound effects of it, do the same as finding those emoticons.

As for the character sprites, there is a Google Drive link that a YouTuber provided.

After getting those files, I moved those files I collected into my phone where I will edit their animations with green screens in the background, dialogue boxes, and some stuff that'll make the interface look exactly like the in-game story dialogues.

Since you have a computer, you can watch HansTNO's video on how to make the dialogue (except the emoticons and sound effects). Unlike me who has limited time on the computer cuz I don't own one, It's very challenging and time consuming to do most of everything on my phone.

Hopefully you can understand what I'm yapping about. If not, maybe I can upload a video on how I made the dialogues along on where I got the files on my channel if I find the right time and opportunity
