Hey! So I was on YouTube (which somehow forgot my watch history and is recommending me videos I've watched) and it recommended me a video from Modern Vintage Gamer about the Nintendo DSi hacking tool "Memory Pit". I hadn't realized that this existed since May.
So obviously, I had to find my DSi and softmod it. If you're looking to do this, please don't look for how on YouTube. Please use https://dsi.cfw.guide.
It took me about 3 hours to go from a DSi that won't boot because the battery is dead to... I press the power button, and it shows me my games! I then proceeded to spend the rest of the day tweaking it, building ROM hacks, etc.
I built 23 New Super Mario Bros ROM hacks from patches. I'm thinking that creating a tool to list games and patches might be feasible.
