Development: ipatix' High Quality Sound Mixer | V2.1 released!

Hmm... what assembly program we should use to insert the routine?
(It didn't insert well when I used karatekid's thumb and asm program)

Do you have a video tutorial on how to insert the routine? Well, it is the first time I'll be using devkitARM (only for this).

Any chance to convert it into Ruby?
Im getting an error when compiling your routine:
hqmusics.asm:296: Error: non-constant expression in ".if" statement
Any help would be greatly appreciated.
EDIT: Nevermind i removed all the if statements and rmoved code that didn't apply to my rom and it worked.

I have a question about editing ".equ USED_GAME, GAME_BPED".
If I use firered U, then should the line be ".equ USED_GAME, GAME_BPRE"?

Update!
So I have finally come around and post my latest update (V2.1) of the mixer. The main thread post has been reworked with new code and cool stuff:

As someone who is 100% uneducated in ASM, is there any way I can use this without taking months to learn ASM?

hai, I like to insert this "high quality mixer" thing to my rom hack, but the problem is IDK how to insert it :(
I have already use the devkitARM -objcopy- but the result is "file format not recognized"
how to compile and then insert it? do you think my the code format must be .asm

so idk how you're compiling this, probably with like make or something
you can also use the compiler from this tut to achieve the same result
just drag the .txt/.asm/.s/.whatever file onto the thumb.bat file and it will output your compiled routine
or you could even run it using command prompt from the file path and then do
Code:
thumb [routinename].[filetype] [outputroutinename].bin
Code:
thumb hqmixer.asm hqmixer.bin
