The stub in place for picture transfer assumed a resolution of 256x192, but in this case, the resolution is changed to 640x480. I first implemented the registers necessary to handle the camera mode/context switch. So I first had to add support for these modes of operation. The DSi camera lets you configure two contexts, each with their output resolution, image format, and various other options (for example, flipping the picture.). It has two modes of operation, named 'preview' and 'capture', which makes sense in applications like digital cameras: preview mode would provide a low-res preview of what the camera sees, that can be displayed on a built-in screen, while capture mode would provide a full-res picture that can be saved. Reason for this is that the camera can be set to output at multiple resolutions.
Nothing exciting.įor example, you can open the DSi camera app and get to the actual camera part of it, but trying to take a picture will result in a system error. MelonDS 0.9.4 already has some very basic camera emulation, but it basically just does the bare minimum to pass the camera init sequence, and then returns a fixed stripe pattern (which is basically just the picture data register returning a fixed value). After all, cameras are the main thing DSi-exclusive games make use of, so DSi emulation with no camera support just feels incomplete. Instead, I went for improving camera emulation. I was thinking of implementing things like SoundEx and microphone support, but Generic said he was going to implement that, so I'm letting him having fun there.
It's well known that DSi emulation in melonDS needs more love. I have some ideas in mind regarding input, like supporting multi-touch and other fun touchscreen-related features, but lately I felt like working on some actual emulation, especially in the DSi field.
Anyway, I have been thinking of cool things I could work on for melonDS. I haven't been very active these days, mostly real life getting in the way, as usual.
