A while ago I found out some loading screens are REAL and some are FAKE and can be sped up, here's a comparison:

How to replicate: CE speedhack, or hex edit 89 35 C0 07 74 00 -> 90 90 90 90 90 90. It's just a proof-of-concept, this will speed up the entire game, it's unusable by itself.

Even outside of speedruns (the FF10HD leaderboards have a place for the cutscene remover mod), this would genuinely be a vast QoL improvement for regular play.

Just leaving this out there, you never know.
