[hatari-devel] macOS : FPU using EmuTOS

[Francois LE COAT <lecoat@xxxxxxxxx>]

Hi,

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 ?

Thanks by advance for any help =)

Best regards,
