NOTE: I deliberately didn't tag this with Python, even though that's what the code I've tried so far has been in, because I'm happy to use any language to solve this, it's really a data conversion problem and the language isn't relevant, feel free to suggest C or Java or anything really.

I've used eXeScope to access the resources in an old freeware .exe (Jetmen Revival 2D). One of the texts found there has a bunch of hexadecimal (I think, they're alphanumeric at least) codes representing sound effects that I've successfully parsed and converted to .wmv in Python, but there's also a bunch of entries that seem to be representing images or fonts (I assume those are just bitmaps of all the letters) in the file that I'm having more trouble with. ChatGPT keeps telling me it's a Delphi (.dfm) image format, but I can't actually find a converter to convert it to .bmp or .raw, and pasting the hex files into various converters gives me corrupted files every time, even after manually removing all the whitespace. I've officially reached the limit of my zoomer knowledge of image formats from 2003.

The file it's all in is called TFORM1 and has a long header with keybinds, stuff about pixels and window size and fonts.

ChatGPT suggested a similar solution to the sound file conversion (which did work for those), also in Python:

hex_data = hex_data.replace("\n", "").replace(" ", "")

# Convert hex to bytes
binary_data = binascii.unhexlify(hex_data)

# Save as BMP file
with open("output.bmp", "wb") as bmp_file:
    bmp_file.write(binary_data)

print("BMP file saved as output.bmp")

...which just gave me a:

not valid .bmp file

in GIMP, then corrected itself to:

hex_data = hex_data.replace("\n", "").replace(" ", "")

# Convert hex to bytes
binary_data = binascii.unhexlify(hex_data)

# Delphi Picture.Data starts with a header, so we need to find the BMP header (starts with 'BM')
bmp_start = binary_data.find(b'BM')
if bmp_start == -1:
    print("No valid BMP header found!")
else:
    bmp_data = binary_data[bmp_start:]  # Extract BMP portion

    # Save as BMP file
    with open("output.bmp", "wb") as bmp_file:
        bmp_file.write(bmp_data)

    print("BMP file saved as output.bmp")

The execution just trips the initial if statement and prints:

No valid BMP header found!

every time, so I think this is just beyond what ChatGPT knows how to do. Here's one of the images:

Yes, I noticed the } at the end of the text - that's not the problem.
