A game ROM contains only the game’s code. It does contain the console’s operating system. When a DS game wants to read your touch input, it doesn’t directly access the hardware. Instead, it sends a request to the ARM7 BIOS . The BIOS handles the low-level hardware interaction and returns the result to the game.
The legitimate way to acquire this file is to dump it directly from your own physical Nintendo DS, DS Lite, or DSi console. This requires a homebrew-enabled console and utilities like DSiDecSubstitute or Wood Dumper to extract the chips' memory to an SD card.
