Mini VMac is a great Mac Plus emulator. But did you know it can also emulate a color Mac II? You need a separate build for it, but it works like a dream.
Here it is running Mac System 7.5 (in all its 256 color glory) on the Unihertz Titan (Android).
Physical keyboard works great. Alt key is mapped to the Apple Command key, which is handy. Though that does mean I need to bring up a virtual keyboard for punctuation. Not ideal, but an acceptable trade-off.
Speed is just about right. Here it is running MS Word. Very usable.
Mouse positioning is absolute. Which means instead of having the screen act like a trackpad, it's more like a drawing tablet. Which is handy for most stuff.
The emulated screen doesn't quite fill the square screen of the Titan. But pretty close. Very readable, even with smaller fonts.
Sound emulation is perfect.
Hypercard, SimCity, Railroad Tycoon... all the early Mac software should be playable here. Need to try a bunch out. See what the upper limit really is...
Also need to test battery life with this (and other) emulators. The battery in this thing is big. I could see this getting all day battery life even running a color mac or dos pc emulator. I gotsta know!
