I could finally write a file to my SD card ... from my Saturn 
Well, I just tested by dumping my Saturn's BIOS, and didn't tried further, because I don't want to find and fix other bugs today 
Top : my Saturn BIOS, dumped from my Freewing device 5 years ago
Bottom : BIOS file in my SD card dumped today
Hex Editor says that both files are identical 
This fixes a nearly 3 years old bug
At that time,
I connected a SD card to my second pad port on my Saturn and could read files successfully. However, file write sometimes failed ... I thought about many possible causes of failures (not enough 3.3V power supply ? Bad luck ? etc etc), but it was a software bug : writing sectors to SD card actually takes longer than reading sectors, and I didn't waited enough for my SD card to finish write.
Changing poll timeout count from 500 clocks to 50000 clocks seems to fix the problem. (Q&D fix, but if it works fine, I won't change it
)
So now, as SD card read/write access works on both yabause and real hardware, it is time to to use it in order to develop new features for my Saturn

So 3 weeks ago, Buu was defeated by Goku, and last week Goku and Uub left Budokai in order to start training ...
Dragon Ball Kai is finally over ... I especially appreciate during Buu's death when it is said something like "he disappeared, and didn't left any cell behind", because I felt my cancer was completely cured (until the last malignant cell) at that time
Dragon Ball Super will start from this Sunday ! Toriyama-sensei, please bring us new adventures and dreams !!!
BTW, I saw Dragon Ball Battle of Gods on DVD, and it was cool
My comments :
- I felt that Toriyama was behind this, because it was about eating foods from the beginning to the end 
- Not born yet Pan is already considered as a Sayajin ... it is strange that it didn't led to debate about pro/con abortion in Europe/USA
Last (technical) comment : I prepared an HDD in order to record Dragon Ball Super on it, and discovered that it isn't possible to copy recorded videos from one HDD to another ?!?
So, NO thanks to :
- Sharp, for making such ugly user interface ... you didn't thought it would be cool to allow multiple selection when deleting recorded movies ?
- Sony, and other companies from "Entertainment Industry", for restricting copy on recorded media from TV.
Ah, everything was simpler during video cassette tape era ...

Today, I made fixes to :
- yabause (debug version for personal use), because UBC doesn't works well on it.
- SatLink, because mkdir function returns -1 when folder already exist 
- PseudoSaturn, various features additions, fixes, as usual 
- BackupManager, in order to display some debug informations.
- Vmem module, various fixes, especially one that took me a couple of hours to understand 
Me when debugging my Saturn projects
(Video grabbed from 9gag.com)
But at least, virtual memory cart is ready for debugging now
Debug session with yabause and SatLinkNiGHTs Xmas header data (bottom of screenshot) was copied
from internal memory to laptop HDDSo, everything don't work right now, but UBC related things and log message output are nearly OK, so that debugging this vmem project will be (maybe ?) comfortable from now :]
... I'm tired
No more debugging for today ^^

I finally had time to use my Saturn, and I could verify that iso/cue "loader" works on real hardware !
Of course it works well when reading from RomFs, and it works also well when reading file from SD card
My test environment ... sorry for the mess
(Micro SD card is located on top-left of the cartridge)
I lost some time to understand why data transfer from SD card was slower than expected, but finally understand why : some debug/whatever delay routine was called when accessing cartridge registers ...
Just putting some #if 0 around this delay code solved the "problem" ^^;
