> A few notes about the port:

> - Requires USE_WXNEEDED, unless building with '-DENABLE_GENERIC=ON'
> which disables all JITs, but then is unplayably slow
> - No releases available since 2016 ("Nobody on the project really cares
> about stable releases. It's too much of a burden to care")
> - Only works with the builtin soundtouch because of a similar issue as
> with citra. In addition, builtin soundtouch errors out during build

> - Needs a large datasize, up to ~16GB (allocated at startup and then
> reduced to what's actually needed).
> - Qt5 is used for the GUI because theres no wxWidgets3 available yet,

> ok?There was temporary confusion as to why dolphin was running on some machines, but not on others. It turns out that I had an old Dolphin.ini still present where Fastmem was disabled while dolphin enables it now by default. Fastmem uses unsafe, but fast memory operations in the JIT that are bound to trigger SIGSEGV in some cases and the intention is apparently that dolphin catches those and then applies the slower usual memory access. I haven't heard of this being an issue on other platforms, but it causes a segfault on OpenBSD. This new draft fixes this by disabling fastmem by default. It's probably best to remove stray dolphin-emu directories in ~/.config and ~/.local/share before using this port. I wouldn't have found the issue with fastmem without the testing by bentley@, Ryan Freeman, and anthk_ (on #openbsd-gaming on freenode). Another hint: sound works with cubeb (in the audio settings).
