I made a video demonstration using Hatari 2.3.0 with a Falcon030
at 32MHz / TOS4.04:


It's the replay of the GEM sequence "EUREKA.REC" with my software,
with the "RECORD.ACC" accessory. The issue is I used TOS4.04, but
I wanted to use EmuTOS 1.0 instead, because I know EmuTOS works with
appl_tplay() and appl_trecord() system calls. But when I switched
Hatari to boot on EmuTOS 1.0, the FPU (68882) was disabled...


So, when I start my Eureka 2.12 software, that makes usage of the FPU,
there's a floating point error (LineF).

Is it a known issue ? Why is the FPU disabled when booting EmuTOS ?

The issue was corrected with Hatari v.2.3.1 booting EmuTOS 1.0.0 ...


Thanks for the patch that was proposed by Jérôme Vernet for macOS.

But I noticed another issue with EmuTOS 1.0.1. The Falcon030 is
booting very slowly, and the hostfs (the Macintosh drive C:) is
no longer recognized with Hatari v.2.3.1. Only A: and B: floppies
are mounted. So Hatari doesn't boot regularly with EmuTOS 1.0.1.
Only EmuTOS 1.0.0 recognize the hostfs, and boots correctly ...

Thanks by advance for any help =)
