Gargoyle's Quest II: The Demon Darkness: Jump Speed Patch

Removes the speed penalty while jumping/falling; jump/fall horizontal speed is now the same as that of walking and hovering. Makes the game faster-paced and feel more like the Game Boy port.

Does make the game easier, notably it relies less on pixel-perfect jumps, again making it more similar to the Game Boy games which are more forgiving in this regard.

Gargoyle's Quest II (NES/Famicom) Jump Speed Patch v1.0


DESCRIPTION
===========

Removes the speed penalty while jumping/falling.

While walking or hovering, Firebrand moves at 100% horizontal speed (1 pixel per frame),
but during jump/fall horizontal speed is reduced to 75% (3 pixels every 4 frames). No
other game in the series does this, not even GQ2's Game Boy port (Makai-Mura Gaiden).

This patch makes the NES game faster-paced and feel more like its Game Boy port.
It does make the game easier, notably because it relies less on perfectly timed jumps,
again just like the Game Boy games which are a little more forgiving in this regard.


INSTALLATION
============

Please refer to your emulator's documentation on how to use .ips files.

Some emulators will by default load .ips files automatically if their file name matches
that of the ROM in some way. For example, if your ROM is named GQ2.nes, FCEUX will
automatically load GQ2.nes.ips if present, while Mesen will load GQ2.ips if present.

You can also patch this into your ROM if you like, so your emulator doesn't have to load
an .ips file at all, using the Lunar IPS tool found at www.romhacking.net/utilities/240/


COMPATIBILITY / TESTING
=======================

I have tested this patch with the following:

- FCEUX
- Mesen, with and without overclocking
- RetroArch with Mesen core, with and without overclocking
- US, EU (PAL) and JP (Red Arremer II) ROMs


PERMISSIONS / TECHNICAL
=======================

Feel free to use this patch in your own hack in whatever way you want.

All it does is change the byte value at position $01815C in the ROM from $C0 to $FF.
This byte, part of the jumping/falling subroutine, kind of works like a speed percentage:
the original value $C0 (192) is 192/256 = 75%, the hack simply increases it to $FF (255)
for 255/256 = 99.6%.
