Hi,
I've done some research on arcade games and have run across a bunch of information regarding various arcade boards used to run the games.
I just have a general question regarding the design of these arcade boards: why are custom boards created instead of using ready-made, off-the-shelf game consoles (like Xbox, PS3, etc.) as arcade hardware?
The main reason I am asking is because I know of one arcade company, Namco, that uses a board that is essentially a PS3. But most companies prefer to use their own [clunky] arcade boards (that are more like PC towers) to run the games. These PC-based "arcade boards" are more like actual computers, and are most likely much more expensive than just using a readily-available game console (with the same graphics/processing capabilities).
If companies like Sega, Taito, and Konami used an Xbox 360 or Playstation 3 as their primary arcade board, they would be able to port the games they want to port directly to the home console with very little tweaking.
So, back to my question! With the increased cost of custom-made arcade hardware, as well as the increased cost and labor to port arcade games to existing home consoles, why would a company want to build their own arcade board?
Thank you!
