What's the problem? Describe what went wrong.

The ruby/sapphire ROM gets written to 0x90000000 in effective memory. When I set a memory write breakpoint of this address or a range that includes it, the breakpoint is not hit despite loading it into memory. I know roughly when it gets loaded and can pause/view it in the memory window.

What steps will reproduce the problem?

Set a memory write breakpoint at 0x90000000. Start adventure mode with an integrated GBA linked. Follow the on screen steps to link.
Notice game links properly and prompts that you may unplug your GBA. Pause execution and notice that the data has been copied into the range but the memory breakpoint never hit.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes. Present in 5.0-19874

Is the issue present in the latest stable version?

Yes
5.0-19368

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

N/A

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

N/A

What are your PC specifications? (CPU, GPU, Operating System, more)
Windows 10
RTX 2060
intel 8700k

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

No

Memory breakpoints don't work for DMA writes, which are used by (among other things) disc drive reads.

Thank you. Someone in the discord actually just made me aware of this... guess I'll have to find a different way to catch it.
