Some bins is png images, start after 22 bytes data

Ah any idea how to open them?

Do a binary cut from %PNG to IEND@B, (included).

guess a name

File Format: bd.bin (Big-Endian)

Here is the structure for anyone who needs it:

File structure:

4 bytes - Total Image Data Size

2 bytes - Image Count

6 bytes - Padding

4 bytes - Image 1 Size

4 bytes - Image 2 Size

2 bytes - Unknown

(Raw PNG 1 data)

(Raw PNG 2 data)

Note: The PNG files are not compressed or encrypted. You can just grab the hex data at the bottom of the file based on the sizes defined in the header, copy the raw bytes, and save them directly as .png. They will open perfectly.

Here's the actual file structure:
 

#pragma endian big

struct e {
    u32 off;
    u32 size;
    char data_start[4] @ (parent.bp+off);
    char data_end[4] @ (parent.bp+off+size-4);
};

struct a {
    u32 data_size;
    u16 c;
    u64 bp = 6 + c*8;
    e e[c];
};

a a @ 0;

and I've also added support for it in my extractor: https://github.com/smiRaphi/UniPyX (https://github.com/smiRaphi/UniPyX/commit/b9b75292ff49a0b8d33d5371081fe1545762653c)

this is cool! but I really don't know how to use python (using 3.11.1)

then read the readme and use google or something like that

Testapp, checked one bin only, so don't blame me, just in case.

Apart from 28 valid pngs bx.bin contains 58 "empty" png blocks (no pixel data), example:
