Greets, its been awhile since I've needed some input in the cab department. With the upcoming release of MK9 I'd really like to get that running in my cab. My understanding is it won't be released on PC, which leaves me with either a 360 or a ps3. After running a dreamcast in the cab for a while, (got tired of swapping discs, MAME+Hyperspin really spoils you) I took it out.
What I would like to do is be able to run a loader like i did with my original Xbox, and just load the game up from the cab via the hdd. It would seem I missed the jtag party with the 360 as they are the only one's able to run homebrew/loaders etc. Which leads me to the ps3. I know you can load them with custom firmware, but are they practical to toss into a cab? My setup is a dynamo "BIG BOY" cab with a multisyc 27'' betson screen crammed in there

.
so any thoughts on how to proceed?
thanks for the space.
