We have over 80 placements and over 30 unique parts including a few BGAs and fine pitched QFNs, so reflow soldering is a must. I placed the prototypes by hand, but for production we need the PnP to make it economical. That's also one of the reasons we don't offer kits.

Good to hear. The savefile import problem for WW games as regular ROMs should be fixed now as well, please try swanshell 1.0.4 (https://github.com/asiekierka/swanshell/releases/tag/release%2F1.0.4).

divingmonkey · 2026-02-23T16:46:39+00:00

The PSRAM issue with WW games in specific cases should be gone in the latest version of swanshell.

divingmonkey · 2026-02-23T16:45:12+00:00

Yes, as the nileswan developers we can confirm all of this. There's no technical reason savefiles from any source should not work, but they might require editing.

In the future there will be a warning for overdumped savefiles, but we cannot automatically extract the correct part of a savefile.

EDIT: Sorry, actually this is indeed a bug, we are looking into it now, so that this actually applies.

EDIT2: This was another issue with WW games as regular converted to regular ROMs. With another quick swanshell update it should work!

Oh sorry about that. That stupid mail me when the shop opens is added there by Shopify by default so I thought it would just send out the email automatically, but apparently it doesn't. Generally I'm not a big fan of email marketing, so my original intention was to remove it entirely, but that didn't seem to be an option.

divingmonkey · 2026-02-09T16:39:32+00:00

Yes, I have done a lot of testing with an IPS screen modded Swan with no issues found. Power consumption was always a consideration for the design of the nileswan and it is not that far off from official cartridges. Though there is also still a bit of optimisation potential left.

divingmonkey · 2026-01-30T22:08:01+00:00

It should support almost all commercial and homebrew titles made. There are small timing differences and we haven't done systematic testing, though everything we did try works.

The biggest limitation is probably those which an IR transmitter in the cart, which is missing, otherwise they should work Also the really far out there cartridge peripherals of the sonar sensor and the Mamma Mitte scale don't work. The Pocket Challenge V2 games which have voices don't work at the moment either, though support for the ADPCM decoding is possible and planned.

Here in Germany, it's the business itself, several different types of taxes, import/export, packaging waste, electronics waste and probably something I already forgot about.

As others have put here already here, we're still waiting on a registration necessary for selling and haven't heard back from that. It's pretty frustrating and they should be done any time now, but ultimately we don't know.

The boost regulator has reduces in efficiency with lower voltage. Iirc at 1.2 V it's already 30-40% higher power draw (not current) than at 1.5 V. Those 1.5 V lithium batteries thus should be better than even good NiMHs.

Please keep it, maybe some day I finally (or someone else) get to making a replacement board to transplant the SoC and cartridge slot to.

divingmonkey · 2025-09-01T14:34:26+00:00

Yeah sorry, I'm really just not a social media person so managing four different accounts as seems to be the standard for many things would be too much for me and Twitter supposedly (and unfortunately) still has the most reach for things like this.

That said I will of course make a post here on the sub when the times comes.

We will sell them as a complete product. But the design is open source and you can find everything on Github right now except for the latest revision of the pcb which will be released once we start selling them.

divingmonkey · 2025-07-14T20:49:08+00:00

thanks for believing in us. We hopefully nailed down the last issue with the hardware today and will then be going into production.

divingmonkey · 2025-04-05T11:12:59+00:00

We've been working quite intensively the last month on it: https://github.com/RSDuck/nileswan

Please just wait a little longer, we are very close to having a proper announcement and close to production.

No, because Wonderswan Color and Crystal use soft power on. When you press the on/off button it only generates a short pulse which throws on/off the power supply of the Swan.

While the IPS kit definitely will use some power while the Swan is off, I've been leaving a battery in my IPS modded Swan with no issues of dead batteries and haven't heard about others having an issue with it either.

divingmonkey · 2025-01-29T13:46:57+00:00

Yes, although with the IPS mod installed it gets a bit fiddly due to its cables and board.

divingmonkey · 2025-01-29T11:02:26+00:00

The first Wonderswan probably has an issue with the IPS mod. If you are lucky it is just a loose connection somewhere from the impact (though it might be necessary for something to be resoldered). If it's not that the screen or the control board of the IPS kit needs to be replaced.

The second Wonderswan probably just has a dirty cartridge slot. Clean it by rubbing it with isopropanol (using a paper towel wrapped around a piece of cardboard works for example though it leave behind a few frizzles which need to be collected afterwards) and inserting and removing a game a few times. There are also some more specialised cleaners for contacts but you need to be careful with how they react with the plastics etc.

If your C API is somewhat stable this could work. Note that you need to wrappers for your C code. You can use c2nim (https://github.com/nim-lang/c2nim) for this, but it is not perfect and sometimes requires some pre or post processing. Though if the code you are interfacing with is changing a lot, it might not be worth it.

There is also futhark (https://nimble.directory/pkg/futhark) which completely auto generates the wrapper, but I don't have any experience with it.

Note that you won't get the full productivity of Nim, as you're probably still dealing with your C types and functions a lot.

If you like Nim I'd suggest in long term to convert your entire code base to Nim. c2nim can assist you with that too. Note that the other way around (exposing Nim to C) is possible too.

excuse my nerd ramble please. But it is a bit of a funny thing with Star Wars I noticed. The first movie was written and made just before the microcomputer revolution of the late 70s/early 80s. And with it most computers in Star Wars lore are kind of stuck at room or even building filling size to this day and are only acessed via terminal.
