I really wanted more glitches to be covered by the iceberg image, like how the BitFS platforms slowly rise over the course of days, due to floating point rounding errors, or how some NPCs blink while the game is paused. Glitches like these have good creepypasta potential.
The "enchanted SC-88 samples" line was something I hoped to see at least mentioned. Old MIDI is really interesting to me. So many soundtracks reused the same sound banks, but in some cases with slight alterations. I remember there is an effort to remaster Donkey Kong Country soundtracks by digging up old Roland and Korg keyboards for the uncompressed original samples, and rearranging the sequences.
But in any case, I thought whatever theory is behind the "enchanted SC-88" implies some undocumented, un-emulatable piece of consumer hardware, which evokes images of some Steins;Gate IBN 5100 craziness.
