So, long story short

I want to build a .dol of a emulator for MSX2 games which recognizes different rom mapper types saved in a romdb.xml.

After building the .dol I want to make a 00000001.app of it and include it in a existing VC .wad

Alternative to building a new .dol from a emulator like openMSX for example, I could edit the existing .dol I extracted from a VC.wad file but I dunno how to do this.

BTW, anyone knows a way to edit .bin files? I want to edit the msx2config.bin, maybe I can change the rom mapper type in there also.

Any insight or hints would be a blast.
Thx

code is compiled into elf files. then the elf in converted to a dol.

And "bin file" is really ambiguous. This is just a generic bunch of bytes. There is no set format, header, size, etc for a .bin. It is just binary data stored as a single file in whatever way the creator felt like storing the data.

Meaning I would need the source code of the emulator I want to use, then compile it into .elf with sdk, then convert it to a .dol and then into .app

Sucks, so no way to edit anything inside the .bin?

Your best choice is to edit one of the homebrew MSX emulators source or config file then recompile it using Devkitpro, providing the sources and makefile are available.

You can edit bin files with an hex editor but you need to know what to modify in there because it won't magically tell you , those are basically binary data.
