The RAM size register is mainly used to restrict the accessible main RAM to 4MB before launching a DS game. I felt like looking at another of the known DSi-mode issues: the fact that we currently don't implement the RAM size register in SCFG_EXT9. The issue was another unimplemented AES feature, and was fixed in melonDS 0.9.3.Sometimes I wish all issues were this simple. One example of a fun issue that had been reported a while ago: the DSi menu would freeze after the health/safety screen if any pictures were stored that could be displayed on the top screen. Not just in the sense of running DSi games faithfully: a good reproduction of the DSi environment is also useful to would-be homebrewers.However, the road to DSi emulation is paved with all sorts of challenges. Sometimes notYou might have noticed that one of my goals for the 1.0 release is to get DSi mode in melonDS up to par with DS mode. Nintendo Ds Emulator Code Works FineThe RAM size gets changed instantly on both sides, and there's nothing fancy about memory mapping either. As a result, the ARM9 changes the main RAM size while the ARM7 is still clearing regions, causing it to overwrite the ARM9's code, and you guess how this goes: kaboom.Yet, the same code works fine on hardware.I had already experimented with the RAM size register, to try and find out if there's anything fancy about it, but there's nothing special at all. However, while the ARM7 has a bunch of regions in main RAM to clear, the ARM9 is given empty copy/clear lists, and all it has to do is clear its DTCM, which is quickly done. In practice, however, there is an issue that kept us from enabling that feature: when it's enabled, the DSi launcher crashes when launching a DS game, while they would otherwise run fine (albeit with the full 16MB RAM instead of the 4MB they might expect).As explained in GBAtek, nocash ran into the same issue:SCFG_EXT9.bit14-15 affect the Main RAM mapping on ARM9 and ARM7 side (that, at least AFTER games have been booted, however, there's a special case DURING boot process: For NDS games, the firmware switches to 4MB mode on ARM9 side, whilst ARM7 is still relocating memory from the 16MB area at the same time - unknown how that is working exactly, maybe ARM7 isn't affected by SCFG_EXT9 setting until ARM7 has configured/disabled its own SCFG_EXT7 register).The basic process of the loader is as follows: the ARM9 syncs with the ARM7 via IPCSYNC, then both CPUs run through lists of memory areas to copy or clear, then the ARM9 changes the main RAM size if required. Depending on how good your game's samples are, you may see an improvement in audio quality. We also added support for touchscreen devices (tablets etc).On the emulation side, we added support for audio interpolation, as an optional emulation improvement. A lot.15 comments (last by poudink) | Post a commentWe bring you melonDS 0.9.3, a tad late, but it comes with a good deal of improvements.First of all, we fixed touchscreen input, it should now work as expected in all screen modes. The ARM9 code is running in main RAM, and the ARM7 has a bunch of main RAM regions to copy and clear: as EXMEMCNT is set to give priority over main RAM to the ARM7, the concurrent accesses are slowing down the ARM9. Then, another test determined that, infact, on hardware, the RAM size change isn't applied until the ARM7 has cleared all its memory regions.We then added code to measure how long each side takes to complete its tasks, and it turns out that the ARM9 takes much longer than expected. My first tests were to see if there was any kind of secret register altering main RAM mapping somehow, but there was none. Namely, touchscreen calibration is now automatically patched in DSi mode, eliminating the need for a recalibration. Hell, we even managed to make the DS play a song solely by regularly changing SOUNDBIAS.There have been several improvements to DSi mode too. Emulating this register means nothing for the average game, but it could be used for cool tricks in homebrew. This goes hand in hand with emulation of the SOUNDBIAS register, too. Every touchscreen digitizer is going to have a slightly different range, which is why users have to calibrate their touchscreen.MelonDS makes up for that in a very simple fashion. Calibration data is then used to convert these readings to pixel coordinates. Last but not least, the DSi title manager allows you to easily install your DSiWare titles to your emulated NAND.A ROM info dialog has also been added under System -> ROM Info.There's also the usual slew of bugfixes and other little additions, you can check the changelog for the full list.For the eventual 1.0 release, we also want to make melonDS less obtuse all around: providing user-selectable paths for savefiles and such, BIOS/firmware substitutes atleast for DS mode, less obtuse DLDI support, etc.22 comments (last by Abhijit Ghosh) | Post a commentIt's no secret that melonDS's DSi mode needs some love, but there are just so many things to do with melonDS.One of the recurring complaints is that, when running in DSi mode, touchscreen input is off, requiring the user to recalibrate the touchscreen, while this doesn't happen in DS mode.Reason for that is that on the DS (and DSi), the touchscreen hardware doesn't return pixel coordinates, but raw digitizer readings. ![]() The current climate is causing the team to slowly melt.Anyway, audio interpolation is one of the emulation improvements that have been requested for melonDS. After taking care of all the details like SHA-1 hashes and whatnot, the initial issue was covered: the DSi-mode touchscreen Just Worked(tm), with no recalibration needed, just like its DS-mode counterpart.With this proof of concept being a success, I took it further:13 comments (last by ^~^) | Post a commentApologies for the slow Summer! We don't have air conditioners in the melonDS HQ. I wrote code to do that with the DSi NAND, taking care of encryption transparently, and bam, I had a viable base for NAND manipulation.I then wrote code to access the user settings files inside the NAND, and patch the touchscreen calibration data there. Torrent mac client setupThe reason the DS does no interpolation is most likely due to how its mixer hardware works, but obviously as an emulator we can ignore these constraints and do a better job.It's also noting that, as far as melonDS is concerned, there are two parts we need to take care of: the DS mixer and the audio output.In the DS, the mixer is driven by the system clock, like nearly everything else. DS games may have downsampled audio to save on space and bandwidth, and the DS mixer doesn't perform any interpolation, which can lead to rough sounding samples. Actually, I had implemented it in DeSmuME back then, and due to the way DeSmuME's mixer works, it was quickly done.So I figured I would give it a try in melonDS.The basic idea behind audio interpolation is to smooth out the audio samples as they're being upsampled. Audio interpolation is well within these bounds.
