/********************************************************************
G-Stream (c)2002 Oriental Soft Japan
X2222 (prototype) (c)2000 Oriental Soft
---
X2222 has corrupt boss graphics because the program roms we use don't match the sprite roms.
--
Hyperstone based hardware
Simple Sprites (16x16x8bpp tiles)
3 Simple Tilemaps (32x32x8bpp tiles)
X2222 uses raw 16bpp palette data instead of 8bpp indexed colours.
todo: sprite lag (sprites need buffering?)
sprite wraparound is imperfect
The following is confirmed on G-Stream only
---
CPU: E1-32XT
Sound: 2x AD-65 (OKIM6295 clone)
Xtals: 1.000Mhz (near AD-65a)
16.000Mhz (near E1-32XT / u56.bin)
27.000Mhz (near GFX Section & 54.000Mhz)
54.000Mhz (near GFX Section & 27.000Mhz)
notes:
cpu #0 (PC=00002C34): unmapped program memory dword read from 515ECE48 & FFFFFFFF
what is this, buggy code?
Is there a problem with the OKI status reads for the AD-65 clone? the game reads
the status register all the time, causing severe slowdown etc, might be related to
bad OKI banking tho.

Dump Notes:::
G-Stream 2020, 2002 Oriental Soft Japan
Shooter from Oriental soft, heavy influence from XII Stag
as well as Trizeal. Three weapons may be carried and their
power controlled by picking up capsules of a specific colour.
Three capsule types:
. Red - Vulcan
. Green - Missiles
. Blue - Laser
Points are awarded by picking up medals which are released
from shot down enemies. The medal value and appearance is
increased as long as you don't miss any.
When enough medals have been picked up a "void" bomb becomes
available which when released (hold down main shot) will create
a circular "void". Enemy bullets which hit this "void" are transformed
into medals. If you place your ship inside this "void" it becomes
invulnerable like in XII Stag.
The game is powered by a HyperStone E1-32XT. A battery on the PCB
saves hi-scores. Hi-Scores can be reset by toggling switch S2.

****OKI BANKING****
Possibly perfect? works perfectly in-game, may not cover all possibilities.
Needs code testing on PCB.
The two OKIs can independently play music or samples, and have half of the
sound ROMs to themselves. Sometimes the first OKI will play music, and some
times it will play samples. The second OKI is the same way. The banks for
both OKIs are laid out like so:
BANK MUSIC SAMPLES
0 X
1 X
2 X
3 X
Bank 0 is the same in both ROMs.
The banking seems to be concerned with half-nibbles in the data byte. For
OKI1, the half-nibbles are bits 76 and 32. For OKI2, 54 and 10.
The bank's '2' bit is the first half-nibble's bottom bit bitwise AND with
the inverse of its top bit. The bank's '1' bit is the second half-nibble's
bottom bit bitwise AND with the top bit.
This may or may not be correct, but further PCB tests are required, and it
certainly sounds perfect in-game, without using any "hacks". */
