Anyone who has tried to use LaunchBox with NEC PC-9801 would know that Neko Project II, the most well known PC-98 emulator, does not accept HDI (Hard Drive Image) files via command prompt, which is what LaunchBox has to do to provide emulators with ROMs. This is especially a problem as all 5 of the first Touhou games, the most well known games on the system, use the HDI file format.
Here, I have created a solution. The zip download contains two files: runner.exe and runner.ahk
To run the program, you need to extract runner.exe into the same folder as Neko Project II, and set the emulator application path in LaunchBox to runner.exe
All this program does is it receives the ROM location from LaunchBox and stores it in Neko Project II's configuration file if the ROM is HDI format then runs Project Neko II. If the file is not HDI, Project Neko II is simply run with the ROM location.
If you want to see the source code for the program, open runner.ahk in Notepad. The program is written using AutoHotkey.
