Tried downgrading.
I tried downgrading fw2, but it's still the nintendo logo repeat.
I don't know where fw1.
(I tested it on the Game Boy large size.
In the state of fw4, it runs well in Game Boy large size.
However, on the Game Boy Pocket, the power is low, so it's a Nintendo logo repeat.)
Before the firmware update, it worked well on the Game Boy Pocket.
However, after installing the 1.04e kernel and updating the FW4 firmware, the Game Boy Pocket does not work.
In the Game Boy Advance SP, the ex flash jr with the 1.04 kernel and the FW4 firmware update runs well, but why does it...
