But im unable to understand, im confused with the base64 part.

For example, on Nillus post he says that "B@" corresponds to the int 128, but when I try to enconde 128 in

I get totally unrelated result "MTI4"

I even asked chat-gpt but has no clue. I'm not sure if it really is Base64 encoding as I never seen '@' in base64 encoded string!

Would appreciate any help, im looking more explanations that help me to understand, not looking for code.

Yeah, I managed to code my own B64 encoder/decoder after alot of confusion... Its not the base64 binary-to-text encoding, its more that the numbers base is 64, just like base2 is binary means only numbers from 0-1, base64 or radix 64 is meant to go from 0-64 only. Has nothing to do with actual "base64 encoding"

That code is broken, function decode_vl64 is not working on line 27, specifically:
value[i + 1] should be value[ i ]

As said, managed to make my own functions. Just impressive, the functions are not documented, and no one ever asked anything about them. I guess everyone just copies and pastes or translates them into other language. There is a "guide" by Nillus that really doesnt explain anything about how the functions work.

At this point im just reverse engineering the LingoScript from the DCRs
