Hacking Supercard Self Test?

[hsforward]

Does anyone know the differences between these two self test modes?

1. Hold L+R Turn on Power to enter self test mode
2. Hold L+R+UP Turn on Power to enter FULL self test mode (PSRAM test need about 1 min)

For the first one, I got:
Test Flash
flash id ok!
flash ok!

Test Sd card
sd ok! no find test file

Test Psram
psram ok!

Now SuperCard DS Version:
English Ver1.01

Test finished

which I think is a good sign. But for the second one, I only got:

Test Flash
flash id ok!
flash ok!

I waited for more than 10 minutes, but nothing else was reported. Is it normal or does it mean my supercard have psram error since there is no report at all about the psram status in the full mode test?

...I didn't even realize it HAD the second test mode. You learn something new every day.

Unless you're getting errors in-game or having saving issues, you're most likely fine.

I just found the answer. For the second test, you need to push A to continue to the next test and B to quit the test.

Oh, then it's like the slot-2 Supercard self-test then. I didn't realize the first one showed everything at once.
