Some sort of feature to decompile everything in a bytecode file back out to its original filenames (that is, if debug information is embedded in the bytecode) would be greatly appreciated for modding projects - as in this project's current state, it can't really be used to modify a game's code, only poke around it a bit. In a similar vain, I would also love to see a tool in the GUI that allows partial code changes to be made in the decompiler pane without having to fully decompile and recompile the entire game - as sometimes, functions cannot be decompiled to begin with (especially switch statements!) and have to be reversed by hand.

Program Version

gui-v0.3.0 (latest)

Current Result

When you search for a function, you cannot do anything with the results.

Expected Result

When you search for a function, you can right-click on a result to open it in the Inspector, or decompile it (like in the Functions Tab).

I was poking around the Dead Cells bytecode with the GUI and noticed that a lot of functions seemed to cut off at a certain depth, even though the opcodes still had more instructions - so I wrote a small test class:

class Nested {
    static function main() {
        var b = 512.0;
        while (b > 5) {
            b /= 2;
            if (b < 10) {
                while (b < 100) {
                    b *= 2;
                    if (b > 50) {
                        break;
                    }
                }
            }
        }
    }
}

Once decompiled, it yields the following output:

class Nested {
    static function main() {
        var b = 512;
        while ([no condition]) {
            b = b / 2;
            while ([no condition]) {
                b = b * 2;
                break;
            }
        }
    }
}

I assume the [no condition] blocks are a separate issue - but the lack of nesting beyond a certain point is far more concerning when it comes to the overall accuracy of the decompilation.

I want to decompile dead cells source code, but when I write .\hlbc.exe '.\Dead Cells\discord.hdll', I get Error: Invalid magic bytes (expected [72, 76, 66], found [77, 90, 144]). The same with ui.hdll Error: Invalid magic bytes (expected [72, 76, 66], found [77, 90, 144])
