HP-41CX Emulator for Android?

[MikeSD]

Thanks, Making progress. That does bring up a button, that's more of an app that sits on top of every app, that allows access to those controls.

I tried it, and it did allow me to install the modules. But not the overlays. Also, I turned off the 41cx and now it won't turn on again. I had to uninstall and reinstall, and repeat. This time didn't turn the calc off and it's ok, except for the overlays.

Also, I can now turn off that trick app and the installed modules remain and the ones already imported, still show up. So that appears to be an "as needed" trick.

Thanks,

Update:

Overlay.TXT seems to work a little. I see the overlay and can select it, but it's very tiny and overlays with the existing overlay, instead of replacing it.

Also, if the 41cx is ever turned off, it can't be turned back on, best I can see. I've only been able to fix that by uninstalling and reinstalling everything.
