Re: [hatari-devel] macOS : FPU using EmuTOS

[Jerome Vernet <vernet.jerome@xxxxxxxxxx>]

i can confirm the bug: FPU settings aren't working in the MacosX GUI.
Curioulsy, only in Falcon mode.

Must be a change in core hatari sources somewhere, or the bug was here
for a while. I will take a look.

Fn-F12 or F12 will display the SDL GUI, then you can change the FPU
settings there. every modification thru MacOsX GUI will erase the setting.
