Gamepad or Joystick controller support. A significant rewrite of the Nintendo DS port, bringing it up to date with.1) Open Emu. The 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.After more than a year in development, I’m thrilled to announce Delta 1.3 is now available and brings support for playing Nintendo DS games to everyone □ Delta, meet DSWe have made a truly tremendous number of changes, which you can read about. 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.
Changing Date On Ds Emulator Download Great EmulatorsIEmulators lets you directly download great emulators for iPhone and iPad without the need to jailbreak. It’s one of the best emulators for NDS on MAC that also comes with almost all gaming. Open Emu is you’re an all-in-one package for gaming on MAC OS. It’s probably the current king of emulation software for MAC OS.Add NDS::SkipFrame to skip rendering next frame (a87e0d9)Unlike DeSmuME, melonDS requires several “BIOS” files in order to work, which can be found & downloaded relatively easily by Googling (no, I can’t link you to them sorry). Skips rendering frames that will not be displayed due to fast forwarding for improved performance. Fix fastmem crash on Apple devices with small VM address space (e40bc37) Fix crash on Apple devices without JIT support (c353e77) Support JIT on Apple platforms (1d27e4c) Supports JIT on iOS by mapping separate virtual memory addresses with different permissions (one with EXEC permissions, the other with READ and WRITE) to the same underlying memory.By enabling just-in-time (JIT) compilation, however, Delta can dramatically improve melonDS performance — doubling the maximum fast forward speed from 1.5x to 3x. JIT CompilationMelonDS can run at 100% speed on most newer iOS devices, but Delta can only fast forward up to 1.5x for a few minutes before being throttled by the system. Beautiful Controller SkinEvery Delta system comes with its own custom-designed controller skin optimized for touch, and DS is no different! Like Delta’s other controller skins, this skin was designed by Caroline Moore and pays homage to the original DS hardware — in this case, the iconic pink Nintendo DS Lite.The standard DS controller skin adapts perfectly to both portrait and landscape orientations. However, all future DS improvements will be limited to the melonDS core, and eventually DeSmuME will be permanently removed. This allows Patrons to keep using any DeSmuME save states they’ve already made, and eventually migrate to melonDS.This new method is slightly more complex than what iOS 14.2 and 14.3 support, but I plan to automate as much complexity as possible so it can “just work” — so stay tuned □ Microphone SupportA small but nice feature: Delta can use your iOS device’s microphone to emulate the DS’ microphone. In other words, melonDS JIT is not supported on devices running iOS 14.4 or later.That being said, there is hope! I’ve discovered a new method to enable JIT on devices running iOS 14 or later — including iOS 14.4 and the upcoming iOS 14.5 — which I plan to release in beta soon. This is because only these iOS versions allow JIT without any restrictions (for whatever reason), which unfortunately was changed in iOS 14.4. Dark Mode SupportThanks to Eric Lewis, Delta now supports Dark Mode throughout the app! Delta already used a dark theme for its main UI, but several secondary screens such as Settings used a lighter theme — which could be especially jarring to switch between in dark environments. Fast Forwarding (up to 3x with JIT, 1.5x without)Delta strives to be the best emulator for each system it supports, so keep in mind these are just the initial DS features! I plan to add several more features — such as local and online multiplayer — in the future, and would love to hear what features y’all want most □ Other Delta 1.3 ChangesBesides DS support, Delta 1.3 also comes with a bunch of additional features and changes to improve the overall experience using the app. DS FeaturesOf course, DS games support all the same features you’re used to with Delta’s other consoles, including: For the vast majority of games this doesn’t matter — but at least now you can hear Mario saying “Bye-Bye!” when playing New Super Mario Bros. Simulate Closing & Opening DS LidEven more niche than microphone support, Delta can simulate closing & opening the DS lid just by sleeping & waking your device. Mac windows xp emulatorUnfortunately, as a visual problem solver it was hard for me to “visualize” how exactly the ring buffer was corrupted whenever I reproduced it (did it fill up too quickly? did it not fill up quickly enough?), but then it hit me: I could graph the memory addresses of the audio buffer’s head and tail pointers, and then I could visually see whether anything strange was going on!Today I fixed an audio bug by plotting memory addresses in Numbers AMA pic.twitter.com/TfA9qjpcD1— Riles □♂️ December 1, 2020Sure enough, I noticed that occasionally the ring buffer’s head pointer would go “beyond” the tail pointer, effectively corrupting the audio data. I spent several days trying to track down the cause, and eventually hypothesized the issue had something to do with Delta’s audio “ring buffer” becoming corrupted. Audio Distortion FixWhen playing games for an extended period of time, Delta would randomly start distorting the game audio for several minutes before (hopefully) fixing itself. Sling tv app for macOption to disable previews when using context menu Quality-Of-Life ImprovementsBesides these bigger changes, Delta 1.3 also contains several quality-of-life improvements, including: Now, RTC is enabled for all games by default, so any game that didn’t work with Delta’s RTC before should now work as expected. Previously Delta would only enable RTC if it detected the game needed it, but this detection was imperfect and led to several false negatives. I decided to check out TPCircularBuffer’s source again to see if there was anything I missed, and to my delight the README had an explicit “Thread safety” section which mentioned:As long as you restrict multithreaded access to just one producer, and just one consumer, this utility should be thread safe.Only one shared variable is used (the buffer fill count), and OSAtomic primitives are used to write to this value to ensure atomicity.BINGO! In my re-implementation, I did not use OSAtomic primitives when updating the buffer fill count, because I (naively) assumed it was unnecessary at the time □ Sure enough, once I updated Delta’s RingBuffer to atomically update the buffer fill count via OSAtomic primitives, the issue disappeared once and for all! Better Real Time Clock SupportAnother long requested bug fix, Delta 1.3 now supports the Real Time Clock (RTC) for all Game Boy Advance games — including Pokémon hacks. So, I re-wrote TPCircularBuffer line-for-line in Swift, and then continued working on Delta Lite without giving it another thought…but as it turns out, this rewrite was what caused the bug in the first place.I checked my code to see why the head pointer would go beyond the tail, but didn’t see anything obvious (I already had bounds-checking logic that should’ve prevented something like this), so I wondered if there was some strange concurrency issue at play. ![]()
