backtrace

Since commit 6048ac5dfeb, found by performing a git bisect, the game Densha De
Go! Professional 2 crashes on startup due to a NULL pointer dereference. I've
attached a backtrace, though in previous commits it used to crash in a
different function. The backtrace was made from a build compiled from the
master branch as of 2026-04-18 (which happens to be tagged wine-11.7).

As mentioned, the culprit is as far as I can tell the change introduced in
commit 6048ac5dfeb, but I'll admit that I don't know why those changes were
made nor why they cause the problem. They absolutely seem related though. It
doesn't seem like it should be difficult to figure out for those who are
familiar with that part of the code, but I could be wrong on that.
