Mega Man V - Harder Bosses

Hack of Mega Man V

Mega Man V (Gameboy) – Harder Bosses
v1.0, by hmsong
Mega Man V (aka Rockman World 5) was the last Mega Man game for the original Gameboy. Mega Man 1 ~ IV were all ports of the NES Mega Man games with slight changes, but Mega Man V was entirely original, with a new Mega Buster (called Mega Arm), bosses, and story. And it was great.
However, many of MMV's bosses were generally easier than the previous game bosses. This was especially true for the past GB-exclusive bosses (Enker, Quint, Punk, Ballade) – while it was nice to pay homage to the past GB games, all of them clearly got weaker, slower, and/or lacking some skills compared to their original selves, thus making most of the battles too easy (Enker and Quint were already easy to begin with).
So, this patch does the following to make the bosses more difficult (but still fair, imho):

• Changes some boss rooms. Specifically, initial Venus's room has waterfalls, initial Neptune's room has slightly uneven ground, most of the Wily Star boss rooms (including the rematch rooms) have different structures, and Sunstar's room has slightly more gravity (phase 1's laser duration was reduced to mitigate this).
• Increases the power of many boss attacks, usually by 1.
• Changes few bosses' behaviors. For example, Enker's big sword wave requires less hits to activate, Quint and Ballade have less "stand-still" time, and Terra's Spark Chaser has less "stay-still" time.
• Changes the Mega Arm's effectiveness for some of the bosses. Specifically, Uranus, Terra, Wily Brain 2, and Sunstar can only be damaged by the fully-charged shot (1 damage for Sunstar, 3 damage for the rest, and CL fails). In addition, Enker can only be damaged by at least semi-charged shot, and Quint takes 1 damage from all Mega Arm attacks, including the fully-charged shot.
• Reduces the damage Saturn and Uranus take from their major weaknesses to more reasonable level. In addition, one of the major weaknesses from the bosses with multiple major weaknesses was changed to minor weaknesses (so that they would only have one major weaknesses, just like all other bosses). Likewise, some of the minor weaknesses from the bosses with multiple minor weaknesses were removed (to either 1 damage or immunity).
• Sunstar is immune to everything except the fully-charged Mega Arm.
• Other minor changes, mostly due to the compatibility issues.

BIG thanks goes to Nezz. He helped hmsong in some difficult parts of the hacks.
If you have any new ideas (big or small), then let hmsong know. He is open to them, and he may be able to work something out.
Applying Notes:

• There are 2 versions – one for Mega Man V US rom, and one compatible with marc_max's Mega Man World 5 DX (apply the MMW5DX patch first, then apply the "Harder Bosses DX" patch).
• This is compatible with all of hmsong's MMV patches, unless otherwise noted.
• Always apply the patch on a new ROM. Do NOT patch the most recent version on top of an old version. It may screw up things and cause unintended effects.
