Probably never, at least natively, due to how much rewriting it would require to make it into an Android/Chrome application. However, Wine does have an Android APK now, so if you can install that, then you'll be able to run Windows software like Lunar Magic through it.
It does indeed look like you have x86, which is good. One less step. Is cross over like wine?
Edit: crossover is made by the same people as wine. It should work.
Start with the xp bottle. The newer you go with compatibility the more likely you'll run into issues. I can't remember if you need .net framework for Lunar Magic. I don't think you do though. If you start using other tools you will though. But let's just get Lunar running first.
.NET is available here (note: .NET Core and .NET Framework are not the same thing, so make sure you pick the right one). It should be noted that the framework is Windows-only though, which means you'll have to install it through Crossover/WINE. (I'm not entirely sure how to do that though, as I don't have a Chromebook)
the closest thing to terminal mode to my knowledge is crosh... and i have never used crosh before so they may be completely different. oh, and another thing, when i go to run .net runtime framework, it downloads two bars in the bottom bar, then freezes. what should I do? run .net runtime core? or dev core or dev framework?
