GBA supercard mini has weird errors

[YraIsConfusedAsFuk]

I hold L and R to do those tests and these are the results:
First one:
Test SRAM
SRAM ok!
Second one:
Test sdram
sdram ok!
Third one:
Test flash
flash id error: 00b9 0000c2ba
flash ok!
Fourth one:
Test SD/MMC
SD /MMC ok!
not find test file
Fifth one:
Now SC Version:1.85


When I boot reguarly it comes up with the UI just without any files appearing.
the attached file is the contents of my micro sd card, it was included with the supercard with some files which i deleted all of for some reason.

I'm really confused, please help

Flash ID error indicates that you're using a clone SuperCard, that should not be an issue and doesn't affect anything else. To me from my point of view, the rest of the tests seem to be okay. But in the end, the SuperCard SD isn't a very good flashcard to begin with. Instead just buy an EZ-Flash Omega DE, you'll get better support out of it.

About fake / clone of SuperCards. Can you provide more information other than the error code? Like the characteristics maybe or the board.

A genuine SuperCard will have a Macronix MX29LV400T 4MBit flash chip and a Hyundai HY62U8200 for 2MB SRAM. If you have a fake SuperCard, you will often find cheap flash memory and SRAM from other manufacturers that do not perform well as advertised and are not made by the same manufacturers. As a result, you will be unable to update using the official SuperCard updates due to the flash ID mismatch, and games may become unstable due to the lack of quality.

Above is a figure showing a side-by-side comparison of an original SuperCard and a fake one.

Differences between real and today's fakes:
1.) Silkscreen for component placement is more thin on the real ones. Fake cards use a different font.
2.) Genuines use Macronix for flash and Hyundai for SRAM. Fake cards use Fujitsu for flash and SI for SRAM.
3.) Board layout should be practically identical.
4.) The thick copper trace next to 'C10' on the fake is far away.
