Homebrew NDS homebrew and Download Play

[RocketRobz]

I want to get NDS homebrew to run through DS Download Play without FlashMe.

Is there a way to modify an NDS homebrew rom to work on Download Play
by replacing a DL Play rom inside a commercial NDS rom?
(or through DS Download Station(ROMs sent from NDS NitroFS rom to NDS RAM)?)

It's possible to modify them to get them to run on other systems without need for FlashMe. It was done with Mario Party DS, where people would DL Play with a bad rom, and it'd brick everyone's DS systems. It'd start up, show a brick wall, and proceed to wipe the system memory. How they did it, though, is beyond me.

Extract DS game files using ndstool (included in DSBuff, DS Lazy, and similar) and find an srl file. If you rename it to .nds it will run in an emulator. Perhaps it would work if it was replaced with homebrew? Probably not, but then again DS Bricker shouldn't have worked. Try it if you want.

There was a thread that showed how to replace the SRL files in Puzzle Planet League so you could send over code. The only things that would actually work were SRL files from other retail games. Homebrew, and even small roms, didn't work. I've tried.

Considering the code that is sent via DLP is signed, 'official' DLP is impossible for homebrew.

It would be possible with a hacked firmware that doesn't check signatures, though. Or with a homebrew DLP client if there is one.

Yet another possibility would be using an official game's binary that has a vulnerability, and exploit it via hacked files or whatever. The header of the SRL and the ARM9/ARM7 binaries are signed, but the rest isn't. Overlays are typically not exploitable, though. The main binaries will check their hashes against hash tables stored inside the binaries.

I used to dump my R4i-SDHC flashcart (with Narnia Prince Caspian icon) as an NDS rom, it was a commercial rom, and it contained a homebrew rom.
I used another homebrew rom in place, and it works!
