The R4400 and R5000 builds differ only in the emulated CPU, but that is a
compile-time choice (the cache model differs deeply), so they are two separate
binaries rather than one installer with a runtime switch. They shared an AppId,
AppName, and DefaultDirName, so installing one over the other was an in-place
upgrade: same folder, same uninstall entry, the previous iris-gui.exe
overwritten.
Pass /DR5000=1 to ISCC to build the R5000 installer ("IRIS (R5000)", its own
GUID and Program Files folder). Without the define nothing changes for the
R4400 installer — same AppId as before, so existing installs keep upgrading in
place rather than orphaning their uninstall entry.

iris-gui pinned its iris dependency to chd,camera,jit,rex-jit,ultra64, so every GUI build carried the v1 MIPS JIT and the N64 development board whether or not the user could reach them. Neither is usable without setup out of band from the GUI: the JIT needs IRIS_JIT=1 in the environment, and the dev board needs an external gopher64 fork plus a POSIX shm bridge the App Store sandbox blocks outright. Move both behind passthrough features (`--features jit`, `--features ultra64`) and cfg-gate the UI they own — the Ultra64 toggle, its Help window and menu entry, and the About panel's ultra64 line. The Debug tab's JIT knobs stay put but now say when there is no JIT behind them. Two consequences worth noting: - The About panel let "off (sandbox)" outrank not-compiled-in for jit/rex-jit. That read correctly while every build carried the JIT; a build without it would now name the wrong reason, so not-compiled-in is checked first. - HELP.md's Ultra64 setup built without the feature and then told you to set [ultra64] enabled = true, which silently does nothing. It now names the flag for both the CLI and the GUI. cranelift still arrives via rex-jit, so dropping `jit` sheds the MIPS translator rather than the compiler backend.
