SDLoader v0.12: run binaries from SD Card and backup/restore saves

Hi everyone,
I have a question regarding the type of MicroSD card to use. I've been leafing through the pages about this adapter since I am getting hit with the infamous "SD card init error" when using my MicroSD Cards. I've tried both a 8GB and 16GB card and got the init error. I just wanted to know if having a 2GB card is a must or can a bigger size be used as long as it's formatted properly?

The size itself doesn't matter.
The partition setup does.
First of all, multiple partitions is probably not a good idea, since we don't know if the library used by the software digests them correctly.
The partition type should be either FAT16, FAT32, or exFAT.
Regarding the SD card init error, you're probably affected by the SPI initialisation problem, which comes from the Saturn itself.
To verify that it's indeed the case, you have to test version 0.127d (burn a CD or put it on an ODE):

If Backup Ram Cartridge was set correctly, the Backup Ram switched（press the R or L button） with no issue，FYI 0.127 can not work on real hardware emu ok
segaxtreme.net
The very first attempt should display an "SD card init error" message.
All attempts after the first one should work as expected.
First let us know if that's the case, and i'll share the trick to use version 0.381.
Cheers.

Just installed 0.127d on my MODE. Boots fine and gives the SD card init error on options A, B, and C. When I tried to either reset or reboot into another version, the same SD card init error occurs.
I'll assume you did more than 1 try on each session, cause that's important.
If you're sure the card was formatted in FAT16 or FAT32 (remember, exFAT doesn't work on 0.127d), then it may be a different issue.
First i would try 0.127d on as much SD cards as possible, to rule out the faulty card (remember, always do 2 tries).
Another possibility is that your Saturn requires different timings than the ones used on both 0.127d and 0.381.
It wouldn't hurt to test some earlier versions (before 0.127d) to verify that, i guess.
The faulty module is a possibility, though not exactly the most likely, especially if the seller tested it before the shipping.

Indeed. I went as far as pulling out a 128GB MicroSD and seeing it that would work with the same results.
I formatted them all to FAT and when that didn't work I tried FAT32 with the same problem still occuring. Since you mentioned it could be a different issue, it didn't cross my mind that I used one of those Sega Saturn Extension cables, instead of destroying a Sega Saturn controller which could be causing the issue. The only two other things I could think of is that I did some crappy soldering job and used the wrong kind of wire or I got the wrong type of board to use.
So far I've tried 0.381 and the first release before I got 0.127 and its still problems. I'm going to go with me possibly doing a bad job on either soldering or wiring and go through it all again.
To be clear, for the concerned machines, the card has to stay plugged after attempt 1 for everything to start working.
Basically, the 1st attempt, despite failing, actually enables SPI mode, which is why all subsequent attempts succeed.
Once the card is removed, SPI mode gets reset, so you need another failed attempt to have it back on again.
I actually own 2 of those cables myself.
I didn't use them for a while, but from what i remember, the contact with the port was unreliable.
Maybe that's a lead right there...
I didn't know you built the thing by yourself, cool.
Good luck with the diagnostic!

I'm having the same issue too of sd error. I have a 32 gb card. I formatted to fat 32. I'll have to do the test on what mention later.
But I got my sd loader from aliexpress
Not sure if they did a bad job on the soddering
Just found this amazing item on AliExpress. Check it out!

After going through an entire rewire process and testing again, I'm going to conclude that it's the cable itself (The extension cable that I used for this.) Did a check on everything and still landing on the error before. It's no biggie and glad that I could get help from everyone here on trying to fix it.
The MicroSD Adapter's are really cheap to get on Amazon. Just a bit of advice for everyone out there who does on an off soldering like myself, invest a bit of money into a good solder vaccuum. It will save time if you don't have the means or capabilities to clear out header pins properly.
If gamepads work properly with the extension cable, that would be surprising, though not entirely impossible.
Hello, and welcome to segaxtreme =]
Pseudo Saturn Kai can't communicate with the SD card by itself.
However, it can be used to load the SDLoader software CD:
1) Burn SDLoader 0.381 on a CD, if you haven't already.
2) Load the CD using Pseudo Saturn Kai, the same way you would load any game.
If the SDloader software was loaded properly, you should see green text on a black background.
At that point, you should be able to access the SD card.
Let us know if it worked.
Please note that i assume your CD player is functional, and you don't own any modchip or ODE.
Hey you got it working on a crt. Nice.
Now it is working! Thanks!
Let's see if this could be included into Pseudo Saturn Kai ;-)
Actually, there's already a patch available for Pseudo Saturn Kai Lite (see post#1).
Unfortunately, it only applies to PSK 6.483, so if you want to use it, you can't use 6.545 anymore.
Additionally, it doesn't work on all machines.
But in your case, if you were able to read|write successfully to the SD card using the SDLoader 0.381 CD, it would work.
Of course, that implies you'll have to re-flash the firmware on your cartridge.
Is there any patch to Pseudo Saturn Kai full?
No, unfortunately.
The only other way that i can think of, would be to execute SDLoader 0.381 from an ODE, or a special cartridge that has a SD slot on it.
Exotic stuff like the USB Datalink would probably work too, i guess.
