The IDA Pro decompiler is a force multiplier for reverse engineering. It turns pages of assembly into readable pseudocode, letting you focus on rather than mnemonics . While it cannot perfectly reconstruct original source (comments, local variable names, macros are lost), it provides an accurate, working model of a binary's behavior.

Go to assembly view, find the instruction where the stack tracking breaks, and press Alt+K to manually adjust the SP value.
