Please don't get angry, but the current configuration of all MSX machines available on openMSX is too european-centric for a japanese standard as is the MSX.
Many models had both japanese and european versions, but they only have european configurations on openMSX. Examples:
- Toshiba HX-10
- Sanyo MPC-100
And many others. A japanese user of openMSX will not recognize those machines as they're configured and think that there's an emulation problem. Maybe this (together with the default machines being also european) is one of the factors that contributes to many people reporting that "it doesn't feel realistic":
There should be an easy way to select between the japanese and european model of the same machine without having to duplicate all those machines. The only difference between the japanese and european versions of the same machine usually is only the VDP and the ROMs. For MSX2 models, only the ROMs change.
And off course, the default model on the shared configuration should be the japanese model, because those machines were designed on Japan an only later adapted for the european market.
