Last day, I was digging in my HDD, and found an unreleased project !
Project name was JWPds, and about Japanese words/kanjis translation tool running on Nintendo DS.
Looking for the meaning of 絵 kanji on my DS :
bottom screen allows kanji input and
kanji meaning is displayed on top screen.
Looking for the meaning of 絵 kanji on my PC with JWPce.
(JWPce is not my project, it is just for comparison with JWPds)
Project is unfinished, because developing things on DS took more time than expected, and also because I learned enough Japanese, hence didn't needed to develop/use this application any more 
Stable binaries and latest (not stable) sources are available, so please have fun with them 
For more informations, download links, screenshots, etc, please have a look in the project page .
If you have any message, etc to send to me, don't hesitate to post a comment to this article
PS for DS fans lost here, and wanting leave a comment : comments require a Turing test asking for my favorite game console, and it's not DS 
Please have a look in my blog in order to solve this test (If you are an human, it won't be difficult 
).
PPS to Saturn fans here : don't worry, I don't plan to shift to DS homebrew development !
The console I like to debug on is and will always be Saturn

From yesterday, I suddenly wanted to turn my DS into a MP3 player, so that I can listen my favorite music while I drive my car
Of course, there are other options in order to listen music in my car :
- GPS navigation unit can read MP3 from SD card, but don't support SDHC ... and my wife (sharing the same GPS unit) doesn't like my music
- My android smartphone can read mp3 but ... I don't like android, and the more I put mp3 in my phone, the longer it takes to boot ...
- My gp2x wiz can read mp3, but takes a while to boot, and the ergonomics of its music player is not so good.
So I want to purchase a DsTwo cartridge for my DS, but it's out of stock everywhere. Is there somebody ready to sell his DsTwo cartridge to me ?
In advance, thank you
And no, I don't want other cheap cartridge, because I like the way to put a CPU into a DS cartridge, and publicly provide SDK in order to use it

So I am making an enhanced version of Pseudo Saturn firmware.
And, as an extra feature of this firmware, I added an iso/cue "loader".
Why the quotes around "loader" ? Because it doesn't emulates CD-block
So, it only loads few homebrew games, but it's enough for me, and I don't want to waste more time on adding CD block software emulator while better solutions (rhea, jhl's "mpeg" cart, etc) already exist.
As an other bonus, I also added RomFs support to my Saturn library
It is like romdiskfs that is widely used on linux, DS homebrew, etc, but it allows file compression, some other features, and ... is probably buggy because I coded it from scratch
(*) Virtual file system is not really new on Saturn homebrew scene, because Piratero already implemented one in libyaul a while ago
RomFs root folder contents. I will load sl_elf.iso file in the next paragraph.
So here is a capture of yabause running sl_elf.iso, after decompressing it from virtual file system stored in Flash memory.
sl_elf.iso is "satdemo" made by CharlesDoty, grabbed from SaturnOrbit's examples (Thank you Rockin'B for making SaturnOrbit ! After 10 years, it still have it installed on my laptop's hard disk
).
yabause running Saturn demo from iso file, near SatLink software I use in order to debug my Saturn programs.Very big thanks to the yabause team ! I grabbed the iso/cue loading routines from yabause sources, and it was very easy to port them
Edit : I removed unused code (CD Block emulation routines, etc) from iso loader module, and .o size dropped from 74KB to 18KB oO
Edit (2015/06/26) : I tested this code on real hardware, and it works too ! Please see
this article for more details.

Last week, I soldered new USB dev carts, so please let me know if you want to purchase one
What's new with theses carts ?
I use new PCB (Rev 2e) and flash chips that allow to store firmware larger that Action Replay firmware :
- Action Replay Flash ROM : 256KB
- USB dev cart Flash ROM : 512KB
It will be useful when making custom firmware for this cartridge 
And, I'm now familiar with using flux when soldering ! Before, I was soldering small pitched parts (typically, the FTDI USB chip) with stain in excess, then using solder wick. This gave good results, but I wasn't satisfied with the visual aspect nearby soldering points :
Before : only stain & solder wick used to solder FTDI chip
After : flux used to solder FTDI chip
And, there are now "ROM cartridge" available for sale !
This is just an "USB-less USB dev cart", but it allows to run Pseudo Saturn firmware, and also future revisions of the firmware with ROM size larger than 256KB available on Action Replay carts. And of course, it is a little cheaper than USB dev cart
ROM cartridge ... well, this is just USB dev cart without USB modules, so nothing really new ^^;This cartridge is interesting in the case you want an USB dev cart for dev things, and another cart for gaming purpose.

In a random shop, I found a bin filled with coconut oil.
Why do I post this picture on my blog ? Because of the funny/wtf warning message on it :
"To people under disease treatment : please ask your doctor before using this product"
Wow, maybe it's like I should ask my doctor when choosing what to eat ? oO
Note if you don't know : oil that is solid at ambient temperature is filled with trans fat, and good for trash, or preparing Mc Donald's burger, but it's the same anyway
And, it's not even it's written "Organic" in big letters on a product's label that it guarantees this product will be healthy !
