ROM Hack How to Compile Files into a .nds file?

[YoshiMoshi]

I have a bunch of files I would like to compile into a .nds file so I can put onto a flash cartridge. It's a homebrew application, in particular this one. I can't figure it out.

FAS1 version 1.7
https://github.com/stenlarsson/fas1/tree/master/FAS1

Thanks for any help!

That source code is ancient. You need someone to update that codebase. And that could take days or months of work.

So it's not possible to compile these files because they are to old?

for NDS specific development:

devkitarm before 2008:
Anything that uses IPC (pre 2008) is ancient code. IPC is a shared memory address where ARM7 and ARM9 can write/read to, problem is alignment and cache coherence with ARM9.


devkitarm after 2008:
Instead, IIRC devkitarm uses:

example: Say you want to send a u32 value from ARM9 to ARM7 using the FIFO_SYSTEM channel

//Send u32value
u32 u32value = 0x11110000;

//ARM7
fifoSetValue32Handler(FIFO_SYSTEM, powerValueHandler, 0);

//ARM9
fifoSendValue32(FIFO_SYSTEM, u32value); //now powerValueHandler method in ARM7 receives a u32value


That aside the video init/IRQ init is the biggest difference I see in there.
