Yes, dreamcast emulation is a way to play the ports that occurred from arcade games. However, not every Naomi game was ported to the dreamcast. The point is that for those with MAME cabinets, it is a great convenience to have MAME emulate the Naomi games directly and further expanding the gaming experience for MAME emulation.
My question is; if it is sooo far away, why would MAME emulators even bother with adding it to the rom list and getting us excited about future capacity if it is "years" away from any functionality? With the speed and efficency of processors getting better all the time, is it so far fetched that a high-performance PC could run a game on a system that is 8 years old using MAME? It doesn't seem that far fetched, but maybe it is just me. What has been the track history on this: When a game is listed in the rom set, how long until it is "playable"? If I remember correctly, some CHD games have taken some time to gain enough speed to run, but not that long. Right?
Thanks.
