Questions about CD-ROM version

[frozentime4]

Hello, I'm new here but I'm interested in buying a (legit) copy of this game. I'm intending to get the CD-ROM version because my friend is selling me one. Unlike me, it wasn't a problem for her because she can read, write, and speak Japanese. I'd rather not waste my cash on something that will end up becoming a paper weight. I have a few questions.

1. Can the English patch be successfully applied on the CD-ROM version of the game? The last word on this from what I've read is from about five years ago and there was mention of potentially accommodating the CD-ROM version (but no guarantees). If yes, is there any word about potentially implementing this anytime soon?

2. What are the key differences between the DVD and the CD-ROM versions of the game?

3. Would the game install properly on my laptop? Windows 7 SP 1 64-bit, 4700MQ (2.4GHZ), 2x Nvidia GTX 765M, GB ROM, 1TB HDD...I'll post more info if needed.
