So an arcade would buy one of these machines with a game on it, and that's the only game the machine will play, and the hardware they buy will be spec'd to that game? If you buy a high-end machine, you can't then load up a low-end game, or even if you want to switch to another high-end game for the same hardware, you have to replace the whole thing at considerable cost?
That just seems all kinds of whack! "I'm gonna buy a high-spec PC to play this game, and when the pundits are tired of it and want to play a different game, I'll chuck out the entire system." Unless these boxes are relatively cheap (in which case why does SEGA persist in them? Where's the money?) why buy an arcade? Surely it'd be cheaper to rig up your own custom PC setup, play for free, buy snacks and drinks at the bar... Or are these machines rented, so the console company can reuse hardware and the cost isn't that high?
From what I recall:
Most arcade games that use PC-based systems (or even some that don't).........have an option to switch to a newer version of software via upgrade kits.
For instance, Tekken 6 came out in both brand new cabinet as well as an upgrade kit. For the upgrade kit, all that was needed was to remove the existing System 256 hardware of Tekken 5.....then just replace it with the System 357 system board where you can install it to any existing compatible game cabinet.
Then to upgrade to the Bloodline Rebellion expansion pack, from what I can remember, all that was needed was an upgrade from a Blu-ray disc (which Namco provides to buyers) which will install over the existing Tekken 6 data.
There are a few exceptions though:
Certain games such as Initial D 4 and Time Crisis 4 required you to buy full cabs (i.e. cannot upgrade software from previous version). This isn't a problem for Time Crisis 4 as the cabinets are very cheap (less than USD$10000 for the Twin Deluxe cabinet).........but it became a problem for ID 4 as even if the graphics are fantastic and the feel of brand new cabinet is neat, the gameplay and physics didn't please many of the existing players.
Though in relation, firmware patches for ID 4 were done via firmware DVD discs that SEGA sends every once in a while. In my case, I was able to witness arcade technicians hooking up the external DVD drive as well as the DVD disc that SEGA sent to them a few months ago which was meant to upgrade the firmware from ver 1.2 to ver 1.5. It takes around 5-10 mins. for the installation as well as asking the Montavista Linux OS to do another system check before re-initialization.
Frankly, there is also a reverse of that. The best example is Arcana Heart arcade version........where you can only purchase system board + software. It's up to the owner as to what game cabinet to use..........as the game does not come in a package that already includes a game cabinet.

Anyhow. I hope that clears up a few things (though I suck at explaining so some things are still confusing). Nevertheless, do kindly feel free to ask more questions to the arcade experts here in this forum
That is all for now
