Hi, I'm not sure what you are after. An LHA is just an archive, so once you extracted it you would just have the executable again. To play it on emulation just create a bootable hard drive directory and copy the file in. Once booted to the shell type renegade to play
Lots of emulation users think “LHA” is a format that is used directly, since the emulators support that. What he’s after is a WHDLoad setup that is packed with LHA. He can then drop that directly into his emulator and not have to deal with Workbench or the command line, since the game will launch automatically.
