Black screen when DivMMC Rom is ON #10

Open Magnetrix opened 1 year ago

(rel 2022.02.16): When DivMMC ROM is enabled at options menu, when trying to boot I do not seeing ESXDOS loading menu and screen stay in black color (rel 2021.04.09). Works like a charm without issues

Just trying new release 2023.01.22 and when select 128k mode with DivMMC rom enabled keep getting only a blank screen instead of normal boot in 128k mode as I described in last post when testing the release from 2022.02.16. If I select rbf file from 2021.04.09 without changing anything DivMMc and Esxdos 0.8.8.9 works great... Don't know the reason...

I forgot to say that the 48k mode works great with DivMMc Rom enabled with ESXDOS 0,8,8,9 in Rbf released 2023.01.22

generally speaking DivMMC is for 48K only. For example, on real ZX (ZX Spectrum core) once you connect DivMMC, you can't go to 128K menu anymore. So probably ZX Next rom wiring/emulating is interfering with DivMMC ROM. May be it's related to MiSTer adoption only.

I also have DivMMC problems in the last two releases (2022.02.16 and 2023.01.22). When loading, everything freezes and garbage is displayed on the screen.
On release 2021.04.09 everything works fine.
On a real ZX-Next, everything also works well.
