[hatari-devel] Re: ST Doom crash with 16Mhz+cache MegaSTE

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi Nicolas,

I did not get your or others' replies on this, but I just applied your 
patch from the mail archive:
https://listengine.tuxfamily.org/lists.tuxfamily.org/hatari-devel/2025/06/msg00046.html

With it, STDOOM works on MegaSTE @ 16Mhz + cache just fine!

=> Please merge!  (after pulling the fixes I've just pushed)
