Thanks Robert. I will send a pull request.

Having same issue on the latest versions in Donkey Kong 94 with “Pause when OSD is open” enabled. First I thought it’s hardware/memory issue, but memtest result is fine

@HiroiSekai could you try this test - https://github.com/antoniovillena/MiSTer_DB9/blob/master/Old/SDRAM.zip?
You need to run all 8 rbf with same rom. If all 8 would pass ok - you are safe :)
I have fail on jtcps1_-520ps.rbf with "rom no good", so it could be problem with SDRAM v2.5 on my side.

Thanks for posting the test.
I ran all 8, and they all say OK with just "ROM" at the end and it loads the Ghouls demo. Looks like mine is okay.

@RobertPeip This seems to happen when the core is paused when cart_act
is high. The core is paused but the SDRAM is not refreshed anymore as you can see in the trace below. Can you look into it?
I made the trace in the first level in Donkey Kong Land 2 and just toggling Pause when OSD is open.

Looks like it gets stuck here waiting for cart_act
to go low which won't happen because it doesn't generate a ce
:
Gameboy_MiSTer/rtl/speedcontrol.vhd
Lines 62 to 66 in dd03f9a
Changing it to below makes it still generate ce
's until cart_act
goes low:
if (pause = '1' and clkdiv = "111" and cart_act = '0') then
state <= PAUSED;
unpause_cnt <= 0;
from gameboy_mister.
Yes, that should be the prefered way: don't go into paused state as long as cart_act is high.
I cannot remember why I have not put cart_act directly into the if clause as you did now.
Very likely just my fault.

This should be fixed now with release 1107.
