i always wanted to mod games but never really got to do some research, turns out its very simple! (kind of)

im using a program called "dnspy" that shows and modifies game code, and another called "Unity Assets Bundle Extractor (or UABE)" to change sprites, 3d models, sounds, and even textures (as seen above), both programs are free and can mod unity games only.

here are the videos that helped me get started:

the game im modding right now (emoji arena) is made by @Kbent1_Dev and he allowed me to mod it :D

if you want to learn modding yourself i would love to help, just keep in mind that im only a beginner :p
