Yeah the game will crash and close within a few seconds if you hit the memory error. I would not normally be able to load this many songs all at once, I've added over 300 if you include the initial 20 pack I released.
I've been working on a handful of 2ndMIX club songs this past weekend. Last weekend I added EuroMIX2. I haven't adjusted X-style ratings for some of these yet.
Changing offsets to your liking is gross and ruins the authenticity, but whatever. I play on a CRT cab with a P3IO, and have the tight stock timings and love it, and wouldn't have it any other way.
