Project TXT Code Loader v1.0 - Load Codes From a Text File in Your ISO!

[UnclePunch]

The dol included contains code to load the file "codes.txt" from the iso during startup and parse the ASCII to create a conventional hex gecko codelist in memory. The codehandler is run after the codes from the .txt have been parsed so there is a minimal impact on performace (if any) due to not calculating offsets and running codehandler code every frame.

The structure of the code.txt file is near exact to that of Dolphin's gecko .ini format. Here's some examples of various accepted formats by the txt loader:

$Codename Here [Creator Here]
0402f47c 38000004

$Codename Here [Creator Here]
*this code does something
0402f47c 38000004

$Codename Here [Creator Here]
*this code does something
0402f47c 38000004 #this codeline something

$Codename Here [Creator Here]
*this code does something
0402f47c 38000004 #this codeline something


0402f47c 38000004 #the codeline waaay down here does something

Here is the code I used to load the .txt into RAM
