Super Castlevania IV PROTOTYPE! - Tool-Assisted Playthrough

This is a tool-assisted playthrough of the recent Castlevania IV prototype leak. The purpose was to explore around the game and have good video and audio quality. There are important things to know when watching this:
- The prototype is not fully functional. After Stage 5, the player is sent back to the title screen, beating Zapf Bat softlocks the game, A-1 is a broken mess that has no progression, and B-2 is impossible to progress due to "spikes" being below the stairs. Passwords let us bypass this, but because the game uses the filename KONAMI, the 'normal' passwords we use don't work. I changed a value in Bizhawk's HexEditor to access everything past Stage 9.
- After every orb grab, there must not be 0 hearts leftover or else the game will underflow the value and softlock. This is why you see deathwarps from Stage 8 onwards.
- ANY candle I did not whip is a small heart. The only exceptions are at 01:52 (Axe), and at 15:30, where the bottom-right corner has a candle containing a small health refill.
- The blue circular things that are mostly under stairs are spikes.
- I did a lot of extra exploring in A-1, but there's nothing interesting I found. One thing to note is the vanilla Stage A starts out as Block A-2 in this prototype. I would've loved to see what the idea behind this block would've been (or if it was an experimental block and it was planned to be scrapped the whole time).
- The in-between cutscenes are not skippable.
- Dracula is not in the game, so I don't know if there are credits. I did not find anything in the HexEditor regarding this.
- IF YOU WANT TO PLAY THIS ON CONSOLE, YOU NEED THE PASSWORDS TO PROGRESS PAST STAGE 5. Check out this video to access all passwords! • Super Castlevania IV P...

    It’s always fascinating to see the ideas that were originally floating around at Konami. The Mode 7 map looks way cooler, IMO, wish they kept that.

    A-1 is so fucking weird. It's like they wanted you to climb up around the inside of a tower in Mode 7, but couldn't get it to work and just made A-2 the starting point in the final game. _Fascinating._

    Correct me if I'm wrong but I don't think that's using mode 7. Instead, it seems to rely on a feature that allows to scroll tiles vertically, and they are using it to simulate rotation (this could also explain why there's more than 1 plane of scrolling). I believe there was something similar on the Sega Genesis, which was sometimes (ab)used to get similar results.

    holy cow, simon's theme had this long B-side before looping? interesting. (the keychange up in production works better tho.) And the treasury was a map theme? And stage 2, i wonder did that get used in any other game? Its interesting, but the production was a much better '2nd stage' tune to keep you energized as you play thru.. and another B-side to 3-1?? Now the length and a-b-c of 3-3 makes sense if multiple tracks were like that... 4 became 8 without a fade in...and whatever decision led to 5-2 becoming a re-versioning of the 2 prelude sections was exactly the right call.

    The first couple levels are relatively the same as we know them in their fully finished state. But after the stage with the haunted ballroom, it gets... trippy, to say the least. You can make out the layouts of the Library, the Torture Chamber (of which a very early version of its background music plays during these stages), the Treasury Room, the Clock Tower, and the Boss Rush at the end against Slogra, Gaibon and the Grim Reaper, which function pretty much without any issues as far as I can spot. It's very impressive that they had a base skeleton (Heh-heh... get it?) of basically the entire game well before they actually started working on the environments and their respective details, gimmicks and enemy placements.

    The only thing I like from this.. and I like it _a lot_ is the "world map." I wish they'd kept that part. The rest of it, I can see where and why it was polished and refined.

    I prefer the most choices made in the prototype, the difficulty is real, the sprites colors are better, better map, too bad the last levels were unfinished, let's hope another protoype will be leaked one day. I prefer the golems and the dragon head skulls in the final version tho.
