Please someone help me Im trying to get liquid crystal and all this I am so lost and I have a Mac If any one can help that would be amazing...
There is a version of VisualBoyAdvance for Mac, but it's outdated so you're very likely to get lots of bugs. So what I do is I play the game on the Windows partition of my Mac. It's quite annoying, but yeah, you can't really do anything about it.
If you don't have a Windows partition, you can still try with VBA for Mac. You download a Fire Red Rom (.gba file), the Liquid Crystal live beta (.ips file) and patch them using Lunar IPS (I'm pretty sure there's a version for Mac).
