Short version: Working Designs.

Long version: Working Designs rather infamously took two-and-a-half years to actually produce the US version of the game after licensing it, due at least in part to Sega losing some of the source code in a hard drive crash. Never fear, though - nothing could stop Working Designs from cranking up a game's difficulty!

General

• As with all Working Designs releases, the script was rewritten. This game is noticeably more restrained with its changes than some, with relatively few injected "jokes", but there are still many, many cases of dialogue being arbitrarily altered or added. For example, an instance of Umi simply exclaiming "Alcione!" in the Japanese version was turned into "This evil suits you well! I'm not surprised you would use children to further your agenda!" in the US version.
• In the Japanese version, almost all dialogue by characters that have a portrait is voiced. The US version cuts out all of it except for the intro, FMVs, and a handful of lines from the villains. The manual attempts to spin this as a feature ("It slowed down the flow of the game").
• Supposedly as a replacement for the missing voice acting, the US version adds optional voice-overs for the game's diary entries. While the manual claims this was done using disc space "reclaimed" from the dialogue voice-overs, all the Japanese lines that weren't dubbed are still present on the US disc unaltered.
• A few portraits have extra animation that was removed in the US version, probably due to a combination of difficulty generating lip flaps and the fact that these animations are very rarely used (e.g. Hikaru has an arm-raising animation that's used exactly once, during the intro sequence).
• There are a handful of instances where one character's portrait was swapped for another for no apparent reason, such as in the dialogue shown the first time the "island" in Lekuido is moved (where Hikaru's "shocked" portait is switched with Umi's).
• FMVs are unskippable in the Japanese version, but can be skipped with Start in the US version.
• The US version increases the number of save slots from three to six and adds the ability to save using the Back-Up RAM Cartridge.
• What the manual describes as "sprite consolidation and reduction" was performed in the US version to reduce lag. The exact changes made aren't clear.
• An option to listen to voice acting outtakes was added as an additional reward for collecting all the Rainbow Amulets.
• Working Designs wasn't willing to shell out the bucks to license the Japanese opening theme, "Yuzurenai Negai", so it was replaced with an original composition.
• An alternate version of the new opening theme was added and made unlockable via a button code. From the Saturn bootup menu accessed by turning on the console and holding A, select "Start Application", press Start, then hold X + B + Z + L + R until the intro begins.

• For some reason, the ending cutscene was re-encoded (or perhaps re-sourced from VHS?) in the US release - the video quality is significantly degraded from the Japanese version. The visual content doesn't seem to have changed, so it's not clear why this was done.

Enemies

Apparently, the two-and-a-half years Working Designs spent putting together the US version weren't for nothing, as this game contains some of the company's most elaborate and involved difficulty changes. Not only do nearly all the enemies do more damage, they've actually been sped up, making them extremely fast and aggressive. The above comparison video demonstrates selected changes - since nearly every enemy in the game was altered in this way, a comprehensive video would be far longer.

(One can't help but wonder how much sooner the game might have been ready without these changes, especially if they had to be hacked into the game using 1996 technology.)

The following sections list the exact changes made.

Stats

First, these changes stem from alterations to constants embedded directly in code stored in various OLXX.BIN files. The "Attack" value is simply the amount of damage the attack does per hit. Offsets are for the US version.

Offset	Name	Attack		Offset	Name	Attack		Offset	Name	Attack
OL05.BIN 0x2572	Caldina Fight 1 Projectile 1	1 -> 3 (+2)		OL05.BIN 0x2A8E	Caldina Fight 1 Projectile 2	1 -> 2 (+1)		OL09.BIN 0x1C0E	Caldina Fight 3 Fan	1 -> 2 (+1)

The remainder of these entries are stored in a table at the specified offsets in 0, the game's main code/data file.

In addition to Attack, there is a second statistic associated with each object that was occasionally changed. Its effect isn't currently known, but it's listed here for completeness.

Additionally, one object had a number of other unknown parameters changed:

Offsets	Attack	?	?	?	?	?	?
JP: 0x69778 US: 0x6A8F4	1 -> 9 (+8)	10 -> 18 (+8)	1 -> 3 (+2)	1 -> 2 (+1)	1 -> 0 (-1)	1 -> 2 (+1)	17 -> 16 (-1)

Speed

The values given here are approximated from the game's native representation of speed (fixed-point pixel/subpixel, with 16 bits of precision for each). An offset of N/A for the Japanese version indicates a new constant was introduced in the US version (due to the quirky nature of constants in the SH-2 CPU architecture).

Note that apart from the changes listed, the fireballs in Bewildering Cave had their speed doubled (by multiplying it in code, hence their exclusion from the tables below).
