No, unfortunately not. I got rid of the 360 awhile back, vowing that I would only play the pcbs after experiencing the slowdown differences between them and the ports.
My son has a 360 over at his mom's house, and I suppose the port being able to be picked up for cheap, I could have swung by their place or borrowed the 360 to give the port a shot which has crossed my mind since it came out.
But honestly, I haven't wanted to ruin the experience by playing the port first before the pcb. Not all, but most of the 360 ports have disappointed me compared to the boards.
I picked up as much over on shmups that the pcb of SDOJ is the better version though, whereas the port like you say is somewhat "rushed," and sloppy, as well as the voices being more annoying than the pcb version for some reason.
But now you have me worried that the pcb may not be too great either, considering...?
