Launch DS Rom directly?

I'm gonna explain myself better. On the DSi you have nds-bootstrap, but that takes a few seconds to actually boot the game (7 seconds before Pokémon Black actually loads, for example), so the actual load times are not correct.
Is there a way to tell an R4 card to act like a retail card with the proper load times? Or can you install normal ROMs as DSiWare or something like that? I'm asking this since I need the proper raw boot up times to do RNG. I also have a modded 2DS XL if it's something that can be done on that.

Only a retail card can act as a retail cart and ds games can't be turned into dsiware

NES/SNES/N64/GB/GBC/GBA/DS games came only in cartridges - except for GBA multiboot and DS Download Play, but those are pretty small sized formats.
That means, you necessarily need a way to simulate that hardware, since those consoles by themselves were never made to run an image file. They *need* hardware in order to do that job for them, and the games were coded taking that into consideration.
One way is using flashcarts, which do that job and allows you to do much more. On DSi side of things, since DSis can run DSiWare and they have a SD slot, nds-bootstrap is a DSiWare app that does all the hard work of emulating how a cartridge works.
There's no way around it, no matter how hard you try. You can use forwarders for nds-bootstrap or flashcarts, but that's it.
