Mine updated smoothly and i was really hoping to like the code but after about 10 games it was Meh. not much new and what was new was just ok. Maybe my expectations were too high. Still no implementation of the cites, the ball locking in gene's head during multiball is cool (like the snake head in metallica), but holding the ball with 1X scoring running? Is 1x supposed to be impressive? i noticed the ball save light still comes on during multiball when gene spits it down the middle, but it doesn't save the ball. I also had one ball where the song switched at the start, but the original songs mode kept playing. I didnt see the spot lights doing anything- maybe i just missed it. The best part of the code to me was instruments rule got easier. I managed to make it to kiss army because of this. I'm not sure when the heavens on fire mode is supposed to start- i completed the grid and nothing happened. Maybe i needed to make the band members solid first.
Overall - its an improvement over the last code, but not nearly as good as i was hoping for. Maybe stern released a "safe" version of the code while they polish up the great code we're all hoping for. -- REVISED, i just read the readme file and have a better understanding of the new rules. I'll try it again tomorrow and hopefully like it better.

i'm revising my thoughts on the new code after making a couple of adjustments in the settings. Its AWSOME. I normally keep all my games in default settings but i was getting so frustrated with the new code that I made two changes that made a huge difference in enjoy-ability to playing it. First i lowered the song completions to light the playfield multiplier from "2' to "1". all of a sudden i felt like i was truly making progress when i finished a song (its not exactly super easy to complete a song especially if your using a cliffy on the scoop). the second thing I did was to change the instrument rule to "lights all instruments". You still have to complete every shot then do it a second time to make progress to Heavens on fire. Once i did this the game seem to make much more sense and everything seemed obtainable. But the most significant part is that it made going for song completions a huge risk/reward scenario. Do you go for another song completion before a super mode/multiball and risk draining/losing your multiplier? The modes can also become very lucrative - on one game i started super ramps with 5x running for 4,500m per ramp shot. It was ultra satisfying.
There are still some annoying stuff in the new code - the lane sound effect is awful, it reminds me of the multiball start of Sopranos. Another issue is the ball save light coming on during multiball but isn't really on. Locking the ball in genes mouth during multiball and getting 1x scoring (wtf is that?). anyways- just wanted to give my two cents worth after playing it a bunch.

Has anyone had issues with demon head shots not registering. I've noticed on two differnet Pro's that shots to the demon head aren't working unless the locks are lit. the opto switch works fine in test mode. I was wondering if it might be a code issue. on my LE it works fine.
