A Prologue is simply a list of instructions that will make some stack space and backup some key registers.Īs mentioned earlier, some functions may not have a prologue due to said functions being simple enough to not require backing up registers. The majority of functions will have a Prologue. Writing similar function(s) from scratch in your source would result in your code being way too massiveĪll functions reside in static memory (mem80).The function(s) you want to use are very complex and writing a similar function from scratch in your source is essentially impossible.The purpose of calling functions in your codes is for 2 main reasons: Obviously, Wii games have their own unique Wii specific functions such as DWC_Login, ISFS_Open, GXDraw, etc. Thus, Wii games contain many generic C/C++ type functions (such as memcpy, memset, printf, sqrt, etc). This guide will teach your how to call (execute) functions for use in Gecko ASM Cheat Codes. In non-coding terms, a function is simply a subroutine of code that takes in input(s), processes them to preform a specific task(s), and spits out output(s) depending on what occurred during those task(s). Like almost all other video games, Wii games are written in a high-level computer programming language (mostly C++) instead of Assembly.
