Mint Explorer is a tool for exploring archive/package files for the Mint scripting engine, found in various video games, notably games from the Kirby series. It parses an input file (containing packages, files, classes, methods, fields and constants) into a tree and disassembles methods when selected in the tree view.
Mint Explorer is written based on reverse-engineering work performed by observing several instances of bytecode files in order to deduce the structure (and meaning of the bytecode) in them.
You can find a public version at firefly.nu/pub/mint-explorer (possibly not the latest version).
Currently, only Return to Dream Land and Triple Deluxe are supported. Make sure that you have a decompressed Mint bytecode archive (e.g. mint/Archive.bin). Open mint-explorer, browse for the Mint archive--it should load, but the loading happens in the main thread which means the browser might freeze for a few seconds.
Once you have a file loaded, you should be able to expand package tree to the left. Packages contain Mint files, which hold static data (sdata), references to different entitites (xrefs), and classes (typically exactly one). Classes contain fields, constants (in K3D) and methods.
Clicking methods will disassemble them and show a pretty-printed disassembly--this is the main usage of Mint Explorer. You can also view the sdata and xref sections of a Mint file (hexdump and ASCII table, respectively), and when clicking a package or file, you get a tally of opcode frequency within this part of the tree (for my own reversing purposes).
The format is documented on the repository wiki: Mint bytecode (RTDL).
