Decompiler Plugins: Some experimental plugins for IDA Pro attempt to map known PureBasic signatures, helping to label functions that would otherwise be anonymous. The Ethics of Decompilation The best "decompiler" is a proactive one: use
Hex Editors: For small changes, like bypassing a version check or changing a string, a hex editor is often more effective than a full decompiler.
