Note: Some kind folk who sleep the proper number of hours per night pointed out you can launch programs from Finder (Open With) to run non-installer programs from CrossOver. I'm still sticking with Darwine but this is an important feature I missed. Bold text is new.
CrossOver is a commercial Wine implementation. Its designed to make installing and running Windows programs easy.
Installing Windows programs. NOT running them, installing them so crossover can run them. This is CrossOver's biggest issue..... it needs an installer. So all those fun doujin games: no installer no luck. That cool app from the internet? No installer no luck. Or so I thought until others told me you can use the Finder Open-With -> Choose (However, CO did not appear in the normal open-with menu for me). A menu item for this IN CrossOver would do wonders since that's where I looked first.
For installers, InstallShield seems to work great with it. Font support is practically non existent however. I have no idea how to add fonts. I could only get one application to install... a LabQuest emulator I had for science class. It would not run because it couldn't preform hardware check. I had issues with the InstallShield installer for ONE however, it might same issue that occurs when attempting to install on EN Windows or it might not; I localize my Windows for games.
Now its a slick program, supported apps like Steam, Office, Quicken... they probably work great. But its so limited by its pre-set boundries making Japanese programs or hobby programs run is flat out impossible. Window management is handled by X11/Quartz it seems and no complains there.
I was able to make Casual Romance Club run by telling CO it was an installer. Not an ideal setup and sorely in need of fonts. According to Libido, CRC doesn't need Japanese fonts unless translation is turned on. Even so, the english should display without issues but...
English text in loading screen: Squares. I quit it at this point.
Restarted: It remembered the name I gave it seems. Still no text.
Music was fine. Images were fine. No lag.
Attack of the squares. The soundtrack squeaked when I advanced the text quickly. This game only has key lines voiced. Notice, its running as in installer in CrossOver. Not ideal.
Everything works perfectly except text.
Voices are fine. If it would just let me run the program as a program (and I then I would tweak the fonts) I imagine the game would run perfectly. (see note)
Don't even look for the Japanese version of CrossOver... its 11550 yen if you can find it. Thats almost twice as much as the English version!
Obviously WINE has great potential, the CrossOver interface to it just doesn't work for these sorts of games at this point.
