Because DSiWare emulation is completely tied to the software being on the NAND, I found that big one on the Internet archive. I noticed it didn't have the DSiWare I was looking for so I took it into my own hands to manually dump my own NAND so I had flipnote studio to mess around with. It didn't take long to notice that when I plugged in my own NAND, the bottom portion of the touch screen on the emulator became unresponsive, and the rest of the touch screen area became offset (i.e. the input is executed a bit above my mouse) Any idea why this issue occurs? I noticed that it only happens through my locally dumped NAND, not the one found on the internet archive.

you need to recalibrate your touchscreen.

melonDS has its own touchscreen coordinate scaling, in DS mode it patches the firmware so that the calibration data matches, but we haven't implemented that in DSi mode yet.

you're not :P

emulators generally do what it takes to provide automagically working touchscreen controls, so I can understand why this wouldn't be obvious.

It would be great if they were able to patch this issue with the DSi firmware. I'm about to make a video on youtube showing how to run all of this in retroarch. Unfortunately, I'm going to be showing this glitch as well. Pretty much makes over half of the games on DSi completely unplayable. A lot of games have the "start" button on the bottom of the touch screen which makes it impossible to click.

Would be nice if retroarch had an option to calibrate the touchscreen controls in the event of an offset situation. It seems like some of the DSi games are unaffected by this for whatever reason. I have a theory that the games work fine if they were designed so it looks like both screens were touching each other. If they were designed so they look normal with the screens having a gap between them, then they have the issue with the touch screen. (only a theory!) If I find a workaround, I'll post it.

So, did you find a workaround?
