One more new PCB color !

Written by cafealpha no comments
As indicated in the title, I tried a new PCB color ! This time, this is yellow


Rare picture where all PCB colors I tried so far are gathered

The manufacturing of theses yellow PCBs took a bit longer than usual : maybe was it because this color is not ordered frequently ? Or just a bad luck with timings ? I don't know, but anyway I'm definitely more at ease with good old green color

Blue PCB in the picture above also needs some attention because it's quite a long time I didn't soldered PCBs with such color. In fact, it was probably the first time for this Gamer's Cartridge PCB revision

So, what's the reason why this article is posted so early ? I mean, pictures of theses PCBs were taken around one month ago, while preparation for one article here is usually in the half a year range, with majority of articles are canceled in the midway of their preparation  Well, the reason comes from accidentally watching TV recently, and realizing that colors match a given pattern !


Gamer's Cartridge, Olympic Games Edition

That would had be the the occasion to do some fancy "Gamer's Cartridge Olympic Games (C) (R) TM Edition" advertisements on all major social networks, modifying prices during this period, make sponsorship with some whatever sportswear brands, but I don't like such kind of show business, and ... the fact PCB colors match those on the Olympic flag is a coincidence

So, I'm glad to introduce you Gamer's Cartridge at the Olympic Games colors ! There's no sponsorship, no changes in the prices, no super event (except this poor blog article), but Saturn projects are still my favorite hobby, which is the most important


PS : I unfortunately no longer have all PCB colors gathered in first picture of this article, so it's not possible the re-take a picture in same layout as Olympic flag.

PPS : there wasn't snowball fight Olympic discipline this time too Let's hope next edition will finally feature competition of a sport which I understand the rules

Happy Birthday Panzer Dragoon Saga !

Written by cafealpha no comments
According to wikipedia, it seems that Japanese version of Panzer Dragoon Saga turned 20 years old this week, so,

Happy Birthday

 Panzer Dragoon Saga !

Hrm, I feel old to hear over and over that games I played in my childhood are becoming vintage ... time flies

So well, I don't want to write an article for the anniversary of each Saturn game That's too depressing, and I prefer to use this time for other things The reason for this article is to help people wanting to play Panzer Dragoon Saga, but not from level 1, and failing to find appropriate save states for use on their Saturn.

There aren't many saves for Panzer Dragoon save files available for importing from Save Data Manager, but good quality saves can be found on Panzer Dragoon Legacy homepage :


The reason why theses saves aren't added to Pseudo Saturn Kai Save Data Manager CDROM is because the readme included with theses saves states that saves can't be hosted elsewhere than on Panzer Dragoon Legacy. I personally think this is a pity, because theses saves are really good.
(2018/02/12 : it seems OK regarding copyright See the bottom of this article for details)

Panzer Dragoon Saga is one of the few games not allowing in-game usage of Gamer's Cartridge. A workaround to that is to use Saturn's internal backup memory.
So, it is possible to import theses saves to Saturn's internal backup memory by using Gamer's Cartridge and Save Data Import feature :
 1. Copy all save data folders from archive to SD card → SAVES folder
 2. Insert Gamer's Cartridge into Saturn, power on Saturn
 3. From main menu, select "Save Data Manager"
 4. Select "Save Data Import"
 5. Browse for save data file where to import from
    Example : SAVES folder → saga_01 → BKRAM1.BIN
 6. Select all saves with Y button and confirm import to internal memory device with A button

Then, it is possible to use theses saves from the game. Unfortunately, Panzer Dragoon Saga is one of the few games not supporting in-game memory cartridge support with Gamer's Cartridge, so the only workaround is to use Saturn internal backup memory.
2018/02/12 : the steps above are still valid, but work on Gamer's Cartridge only. Next release of Pseudo Saturn Kai will feature theses saves directly from Save Data Manager, so that theses will be available for Action Replay cartridges users too (See the bottom of this article for details)

I hope I will be able to make this game compatible with Gamer's Cartridge in the future ! I recently tried to find what's causing this game not working ... and realized it would be harder to fix (I thought game was re-authenticating CD-ROM just before starting to play, but I didn't found any code doing that)
I'm not a genius programmer, but on the other hand, I don't give up on the first failure I meet, so hope next attempt to fix support for this game will be the good one



Update 2018/02/12
: I just received the agreement to add theses saves to Save Data Manager More details can be found on Panzer Dragoon Legacy forums, and screen copy of related posts are available here for the records.
Special thanks to Solo_Wing, who solved this problem in a couple of messages ! Please keep the good work

New PCB Color !

Written by cafealpha 2 comments
So I'm currently preparing next batch of Gamer's Cartridge, and am glad to introduce new PCB color


Gamer's Cartridge PCBs in various colors

I unfortunately didn't had blue Rev 3.3 (b) PCB when taking the picture above ... in fact, it's a long time I didn't soldered blue PCBs


The main interest in soldering PCBs with different colors is to make soldering activity funny, which is important for me since cartridges are assembled by hand : if making cartridges would become boring, I would prefer to stop everything rather than automatize assembly process !

My impressions after soldering a black PCB are ... a bit mixed : yeah, the PCB looks cool, but there's no contrast between tracks and isolated areas, so I definitely wouldn't use this color for new projects
One example of this lack of contrast can be found in cow logo, whose rendering is terrible in black color :
Cow logo on black PCB ... playing hide and seek

Among PCB colors I tried so far, I personally prefer ... standard green color, and then maybe red color. Also, I still didn't tested yellow color, so let's try it on next batch  I fear that contrast won't be better than on green PCB however

PPcenter donation system updated !

Written by cafealpha 4 comments
More than 11 years ago (from winter 2005 ?), I had a "donate" page stating something like "send your money and I will make cool things for Saturn on my free time".

During there 11 years, I received 15 US dollars.

And within theses 15 US dollars, I declined 10 because they were generously donated in exchange of "future help" in making a game for Saturn.

So that's something like 45 cents per year, which is also around 3.8 cents per month. I didn't checked in details, but that should be something like one Skittles per week. Not one bag of Skittles, but one bloody skittles. Per. Week

Fortunately, this era now ends, because I officially announce that I changed my donation system from "send your money and I will make cool things for Saturn on my free time" to "Send everything except money, and I will make cool things for Saturn on my free time. And even if you don't donate anything, I will make cool things for Saturn on my free time anyway."
More details can be found on my donate page

And to make it clear : the motivation to change donation system is not related to money : I just spoke about money received so far in order to write something funny in my blog

I make Saturn things for fun, and not for money. As some examples, I started to design rev2f PCB in hospital room from one week after undergoing cancer surgery, and Virtual Memory Cartridge add-on for Pseudo Saturn Kai was developed and tested during my post surgery chemotherapy. Theses helped a lot to think about something else than medical things during theses times.
I don't say that Kicad and gcc are a cure for cancer (), but theses were very good help however.


And to make it clearer : yes, I sell Saturn cartridges, but no I don't make a living from selling theses. I'm not even sure I produce enough carts in order to pay every-day's breakfast from cartridges sales benefits

Gamer's Cartridge out of stock :]

Written by cafealpha 5 comments
Out of stock ":]". I'm glad to have finished this batch
I don't plan to sell Gamer's Cartridge for a while, because stock of parts to build theses cartridges (electronics components, PCBs, labels, etc) is currently very low here. I'm even lacking of bubble paper used when shipping cartridges

So, what's next ? Of course, Saturn stuff  I plan to use this "break" in cartridges manufacturing and sales in order to continue Pseudo Saturn Kai development.
Main feature to add is cheat codes, which is a bit "heavy" one to implement, because processing in order to make cheat codes working isn't documented in details.
But that will be done ! Also, there are some side quests here and there regarding Pseudo Saturn Kai features. I plan to implement as far I can, so it will be limited only by my free time, my motivation, and flash ROM remaining on cartridge

Seeed Studio, very classy and realistic

Edit (2017/05/11) : finally back in stock
I catched the occasion to make some minor improvements to my homepage, such as adding anchor link to some sections, adding some directions for Japanese users, etc ... and I'm already full up with writing HTML

Edit (2017/05/12) : half of the stock already reserved oO
data/images/20170512_escalated_quickly.jpg
Cartridges are assembled by hand, hence stock is small, but I'm impressed anyway
