Hooah Trace
a simple yet powerful instruction tracing using frida stalker - supporting arm64 and x64
when you want to use this
when you need to trace at single instruction and perform additional operations or alter the code flow.
when you need to get a proper understanding of what's going on down there with obfuscations killing the party.

colored: true,
// custom space between blocks
treeSpaces: 8,
// include involved register values data
details: true

- add medium-level decompilation
- add asm relocation
