TheUltimateDoomer666

It is, or it used to be. I got sealed copies of the older DOS-only (pre-DOOM95) CD-ROM big box releases of The Ultimate DOOM (with the poster) and DOOM II from eBay in 2017. But this Helmet Collector's Bundle would cost me a whopping AU $200, and that's not even including shipping.

I checked some YouTube videos, and yep, the key is behind a secret wall. Wow, the manuals lied. (I checked the manuals from both the Wolf3D and SoD boxes; they both make the claim that all the necessary items and elevators are located in the normal, non-hidden passages.)

The game's manual specifically says that items required to beat the level will never be hidden behind secret doors. I'm pretty sure the Mission packs for Spear of Destiny broke that "rule", though.

Wolfenstein 3D is much harder. The simple gameplay is pretty dated, with hitscan enemies (specifically, the Mutants) that can attack you the instant you press the space bar at a closed door.

You may be surprised at how common it is for game developers to spoil the final boss in official previews or screenshots: Preview screens in the shareware versions of Blake Stone: Aliens of Gold, Bio Menace, Hocus Pocus, Realms of Chaos, and Duke Nukem 3D. A screenshot on the back cover of the US release of Sonic & Knuckles (not counting the extra/unlockable boss). A screenshot for the Steam release of Blake Stone: Planet Strike. Screenshots on the boxes for Duke Nukem 3D, Duke Nukem 3D: Plutonium PAK, and Duke Nukem 3D: Kill-A-Ton Collection. The blurb on the box for Quake's second Mission Pack (it says what the expansion's final boss is twice).

In Cakewalk Pro Audio, the solution is to delete all of the song's "Patch" events (like the one shown above) from the event list. The sequencer will then instead use whatever instrument has been selected for the MIDI track. I do not use Sekaiju, but presumably that sequencer would work the same way.

FL Studio is a DAW and not really optimal for MIDI sequencing in my opinion. The Cakewalk sequencers have features that FL Studio doesn't even support as far as I can recall. Cakewalk Pro Audio 9.03 for example supports saving to multiple MIDI formats (MIDI Formats 0 and 1, and RIFF MIDI [RMI] Formats 0 and 1), and has an editable event list. Also, FL Studio inserts superfluous commands when it exports MIDI files, which needlessly increase the file size and can even cause other subsequent MIDIs to play incorrectly in a PWAD or such (this issue actually happened when users were submitting MIDIs for one of the community projects here). There are some musicians who use FL Studio to create MIDIs for DOOM levels though, so it definitely can be done, but for me Cakewalk has all the features I need. I haven't used Cakewalk Express, but I'd still say that would be much better for sequencing DOOM MIDIs than FL Studio is (Jimmy uses Cakewalk Express 3.02).

A DOOM movie was "in the works" in 1995, in the sense that Jay Wilbur inked a 1 year option with Ethos Productions.

I still use Cakewalk Pro Audio 9 to make and edit MIDIs.

"You are now a furry."

There is no efficient way to do that aside from learning how to make music/sequence MIDI. Alternatively you could find someone who is willing to transcribe it, although they probably won't do it for free due to the work involved when there's no tab or sheet music available.

That actually sounds like a bad design choice or oversight. I'm glad I haven't used that option. I always assumed it would simply warp you back to the beginning of the current level.
