The long answer is more nuanced. There are two categories of tools that claim to do this: Searching forums and GitHub often leads to a ghost: a tool called UnPureBasic (or UnPB ). Users whisper about it in Czech, French, and German forums from 2006–2012. The lore suggests it could take an executable compiled with PureBasic 3.x or 4.x and reconstruct a .pb file.

However, LLMs still hallucinate. Always verify the output. The cold reality: There is no functional PureBasic decompiler that will give you back your .pb sources. The lore suggests it could take an executable
