It appears that the recent release of Delta on the Apple app store is giving us extra attention. While this is nice, I would like to state a few things. First, we the melonDS team are not responsible for third-party ports (with the exception of Generic supporting the Switch port, since he made it). Our scope is limited to the melonDS core and the desktop frontend (ie. the Windows, Linux and macOS versions). If you are running into issues with Delta, or with any port of melonDS: you should contact the authors of that port. Members of our community may also be able to help you, but contacting ..read more

In this post I showed an attempt at running two melonDS windows at the same time. Just a silly test, but groundwork for more. What became apparent during this is the fact that our current configuration system won't do. The current config system was born out of simple needs: at the time we just needed to store a few configuration values. The keyboard and joystick input mappings, and misc settings like direct boot or 3D renderer threading. For this, a simple pseudo-INI format was deemed enough. The config file is named melonDS.ini, but it is just a simple key-value pair format with a custom pa ..read more

Long time no update. Sorry about that. I'm getting better, though. Anyway, I recently felt like getting back into melonDS dev. I figured that trying to fix some wifi bugs could help me build up momentum and motivation I'll need to finish the big refactor. The point of the big refactor is to lay groundwork for turning netplay from a clunky proof of concept into an actual finished product. But netplay or LAN won't be very useful if the underlying wifi implementation is malfunctioning... The first bug I looked at was that weird bug in Meteos: when starting a download play game, if you're usin ..read more

This is just a quick attempt at supporting multiple windows. There's still a whole pile of issues to fix, but it's looking promising so far. This is not only part of the ongoing refactor, but would also pave the way for separate windows, a feature that has long been requested. I'm having a bit of a question there: if we got multiple windows, which one should have the OSD? The main window? The currently active one? All of them? Other than that, sorry for the lack of updates lately. January has been rough for me, but things are getting better. I've also been caught in a fun side project th ..read more

(to those who celebrate, that is) As I have received and set up my new laptop, I've been able to work on melonDS some. The goal is still the same: to adapt melonDS for supporting multiple instances within one process. The frontend is proving to be tricky, because it was largely built without many regards for code quality. Originally, the frontend was just quickly built around the program entry point in main.cpp, as it just needed to provide a means to use the emulator. We had a simple window, a dedicated thread to run the actual emulation, and that was it. Obviously, over time we added var ..read more

Sorry for the lack of updates lately. Mental health has been rough. Hopefully it's going to get better with the Christmas holidays... What's new since the last post? I had started working on refactoring the melonDS codebase for the ambitious changes to come. JesseTG mostly finished the work on the core, so that's one big thing out of the way. The frontend code is now going to need adequate refactoring too. That's, well, more work. We'll get there over the coming days. On my side, I (finally) ordered a new laptop, so I'm waiting to receive it and set it up before I do more big work on melonD ..read more

Today melonDS is officially 7 years old. To celebrate, like last year, have a new version of the melonDS icon, recolored to the same orange color as 7 itself: (if you're wondering about these colors: I have synesthesia, that's all) I'm sorry for the lack of new releases since 0.9.5. It's been one year. That being said, we have big plans for the next release. I'm not going to go in length about these, the previous posts detail the plans well enough. Just bear in mind that we're currently refactoring the melonDS codebase, so things may get a tad unstable while this is ongoing. Other than ..read more

Basically: melonDS has got a fun little dialog for changing the date and time now. Basically what it does is show you the current date and time of the emulated DS. You can change it to any date and time, or you can reset it back to your computer's date and time. What you set is saved as an offset in seconds from your computer's time. Every time you launch a game, the computer's time is used as a reference to calculate the emulated DS's time, and then melonDS does its own time counting from this point. This also means that, unlike the previous behavior, if melonDS runs too slow or too fas ..read more

Two main things this post will talk about. The RTC, aka Real-Time Clock. The DS uses a RTC chip to keep track of the current date and time. melonDS has had some RTC emulation since the early days, because it was a requirement to get the firmware to boot, but since then, that RTC emulation has been pretty much barebones. Basically, all it does is return the current system time from the host. While it's good enough for the most basic purposes, it comes with a number of downsides. For example, we've had several requests from end users about changing the time inside melonDS. Currently, the only ..read more

As of today: LAN gameplay between the two computers I have at hand over here. LAN is actually fairly close to a finished product, now. It's obviously still a bit rough around the edges, may be a tad unstable, but from my testing it has shown to be pretty smooth. From this point, I encourage anybody who is interested to grab the experimental builds from our Github CI. It's the runs labelled 'season2 test PR'; note that you will need a Github account to download them. But if you're motivated, please give them some deep testing, abuse them in whatever ways you can think of, and report anyth ..read more
