Homebrew Maker Code Init- Programming

[Knightsurfer]

So I was wondering, is there any programs that devkitpro comes with that automaticly sets the maker code and save type in the rom while compiling,
it's just annoying having to hex edit my rom each time is all.

What I mean by maker code btw is like how Pokemon Emerald has the maker code: BPEE


Also yes, I am aware there is a prefix system on this forum, I only realised too late.

Save type is not a header value or anything. Most emulators/flash carts will search for the known ASCII values that represent it literally search the game for SRAM, EEPROM and FLASH and then have the sub type be nearby) and go from there depending upon what they do (don't think any are solely database driven).

Maker code is also a different concept to what you describe

What you describe is the game code but I take your meaning anyway.

Various options here. I have not got modern dkp installed but a lot of GBA stuff went headerless. Might be easier then to simply do a copy /b or cat command either afterwards or in the makefile with a premade header (I don't imagine you will be changing it). https://no-intro.org/tools.htm has GBATA and http://www.gameboy-advance.net/rom_tools/flash_advance_toolkit.htm which is what most use to sort headers in such scenarios (the former fixes minor problems, the latter is more for going from scratch).
That said I am sure there is a program to give your homebrew a header in DKP somewhere.
