Amazing find! I, too, hope the game could be ported over to the 5200, although I worry about the controllers being a bit of a problem (like Asteroids).
I'd think the 5200 controllers would be well-suited to Sinistar, as the arcade game was intended for pseudo-analog input, and 2 fire buttons.
Of course, I can see where centering/deadzones would rapidly become an issue in this one, too.

Great news! Sinstar is an awesome, evil, blood pressure-raising shoot-fest. The graphics here look great and faithful.
I have heard rumour of an "original" ROM for the arcade machine, finalized before the jackass corporate guys made the programmers crank-up the difficulty. Anyone know more? HHMmmmmmmmm....

Hmm, according the one of the guys that worked on Sinistar, the programmers didn't like the idea of making the game harder. So they burnt some copies of the original Sinistar WIP code and kept the ROMs. The idea was that someday the programmers would treak the gameplay to their liking and release that.

Way I heard it was that they thought the game was perfectly balanced as-is, but you can't tell your boss" You're crazy and I ain't changin' nothin'" so they all burned sets of the then-current ROMs off before they started in on the "upgrades."
They couldn't tweak it to their liking and then release it, because Willaims owned the game, and still does.
And a set of ROMs believed to be from the AMOA show Sinistar first appeared publically at have long since been dumped(surfaced back in '98), and are believed to have the perfect gameplay(it's known that they're easier, and that it was made harder based on feedback from vendors at the AMOA).
MAME calls the set "sinista1" or "Sinistar (prototype version)" depending on if you're looking at the 8-char game name used for ROM image sets and loading purposes, or the full-length name used for informational purposes.
