Last time I checked hardware (with the exception of pens or pencils) nor emulators could write games Seriously, you could always ask MindRec themselves, I'd assume it was tested prodominantly in emulators for the sake of speed and cost of CD-Rs. "Development hardware" is not at all necessary today in making a game for a well documented system. In this case it's not even likely since the Hu7D package, besides being PC-98 reliant, is completely obscured by today's proficient crossassemblers and emulators for debugging. Additionally, the Hu7D while being the (only?) package for PCE, leaves you stranded for CD games and Hu7CD is nowhere to be found.
