This document briefly describes how to play pc engine games on cd with Hu-Go!. It is also useful for playing simple .iso files, just skip to «CD system rom configuration».
Under Windows, CD-rom devices are automatically detected and the first one is used. It normally corresponds to the lower letter one. It can be changed but not easily.
Under Linux (as it is the only other platform supporting reading from raw cds), you must set the device path with the option called «CD path» if it's not «/dev/cdrom».
When playing cds or .iso files, Hu-Go! needs a cd system rom to provide the cd bios functions. To have Hu-go! automatically start it when loading a cd or .iso file, you must set the option «CD system filename» in the options. It should point to a rom which provides cd bios functions. Usually this rom is called «syscard.pce», «syscard3.pce», «syscard30.pce»,...
If you didn't set this option field, Hu-go! will try to find such a rom on your system, looking for names «syscard.pce», «syscard3.pce», «syscard30.pce», «cd-rom~1.pce» on the following locations : current Hu-Go! binary location, parent of Hu-Go! binary location, «c:\», «/usr/local/lib/hugo», «/usr/lib/hugo».
When you try to load a cd and no rom could be found, an error
window will pop up.
