Arne write a FPU Emulator so you can use DML FPU Test Soft with Mega STE or Atari SFP004 ...

I did not know that. I don't think he is a member here. But doubt he would help port it to GB6 anyway. But like I said before, FPU is not really useful. I'll probably just take down the GB6 page as its always the same that people complain about fpu or they complain it doesn't work right when they have no idea how to use it. Just gets very tiresome after a while :roll:

I am not informed but why does Gembench 4.03 support Line-F and also io-mapped FPU and Gembench 6 cannot?

I already explained this!
https://www.exxosforum.co.uk/forum/viewt ... =10#p71541 it's also explained in the readme since the very first GB6 build.

Write or found - but in anycase - that's awesome! I will look at that when I'm working on my MSTE next time.
@exxos - what it does is adding Line-F FPU emulation to plain 68000 machines, so, the code in GB6 would already work as-is as long as the FPU emulator has been executed first.

That sounds cool. So why do people keep complaining about it then :roll:
Will have to look into that.. If it's just simple like running a PRG , I could add that into the GB6 docs.. Where nobody will read it anyway :roll:
