Uploaded a new build to address a rendering bug which was introduced back when wiggly wall workaround code was incorporated. This was a nasty one and visible as early as E1M1 of the original game!
Additionally, made the fix togglable and added a menu item for that (it's off by default now), and updated about/credits section (again).
Also tossed in shims for No End in Sight and BTSX E3 Preview as well as a modified version of NEIS E4 map with unblocked secret exit (which actually make the shim useful - look for it in GOODIES of the full distro).
Finally, restored STAGE4 (June 2023 build) in full distro, which was for some reason gone in recent uploads.
Happy festive season!
