Okay. So its better to have reliable mirroring than random data in higher byte, i agreed.

This is exactly what i did, its the easier and faster way but is not fully correct, as Till showed just above...


I have also change the line

Code: Select all

IF oddout=addr(0)  THEN

to:

Code: Select all

IF oddout=addr(0) AND memmaskmux(5 downto 4) = "00" THEN

This is important.

Does a minimig-build including these fixes exist? Or shall I set up a Build-Environment?

Could it be possible to add support for 4 IDE devices, like on MiSTer?

That would involve a big firmware work, too. I'm not sure if there are enough RAM left for that.

Thanks slingshot for your new core and all your efforts on the MIST !
I tried the new one with a problematic case: Super Offroad cracked disk Version and this still does not work.
Can anyone confirm ?
