Main CPU : z80 (with encryption, external to z80)
Sound CPU: custom T5182 cpu (like seibu sound system but with internal code)
The SEI8608B sound board, which features the T5182 "CPU CUSTOM" and YM2151, also
has unpopulated locations for a 76489AN, 2x MSM5205, 2x 27512 EPROM (presumably
for ADPCM samples), and additional TTL chips to support all these.

Raiden (Korean license) (c) 1990 Seibu Kaihatsu
Raiden (Taiwanese license) (c) 1990 Seibu Kaihatsu
The alternate hardware version is probably newer than the main sets.
It looks closer to the newer 68000 games, while the main set looks
closer to Dynamite Duke (1989 game) in terms of graphics registers used, etc.
As well as different graphics registers the alternate set has a
different memory map, and different fix char layer memory layout!
To access test mode, reset with both start buttons held.
The country byte is stored at 0xffffd in the main cpu region,

Sound: YM3812, OKI M6295
Custom ICs:
- SEI0160 QFP60 (2 on main PCB, 3 on OBJ1 PCB)
- S1S6091 QFP80 (4 on main PCB, 4 on OBJ1 PCB)
- S1S6091 or SEI0181 QFP80 (4 on main PCB, 4 on OBJ1 PCB)
- Altera EP910PC-40 EPLD, one next to each V30
- SEI0050BU DIP40
- SEI80BU DIP42
- SEI80BU DIP42 (next to encrypted Z80 ROM)
- SEI0100BU "YM3931"
- many CMOS Gate Arrays
- SEI0010BU TC17G008AN-0025 (2 near mask ROMs, 1 near CHR ROMs)
- SEI0021BU TC17G008AN-0022 (4 between mask ROMs)
- SG0140 TC110G05AN-0012 (2)
One of the sets is SEI8904 with SEI9008 subboard.
The following alternate main PCB types have been observed:
1. "SEI8904 MAIN"; custom chips are similar to the common dedicated
hardware, but PCB layout is vastly different, resembling Dynamite
Duke (Seibu's previous game); the format of CHR RAM is transposed
here. One (undumped) set, perhaps the earliest revision of the game,
has a half-empty SEI8904-ROM subboard which has the BG and sprite
tiles in ROMs with even numbers starting at 20, 30, 40; another set
instead has a SEI9008 subboard that replaces these 12 ROMs with the
SEI420, SEI430 and SEI440 mask ROMs found on later non-bootleg sets.
2. Newer Seibu hardware, lacking the encryption PLDs and many of the
older-generation custom ICs listed above, though the mask ROMs and
OBJ1 subboard remain the same. The graphics registers here are very
different from previous licensed sets, having the CRTC-style format
of all subsequent Seibu arcade games.
3. Korean bootleg hardware, with no custom ICs and an enormous subboard
with four ROMs amidst over 100 TTL chips. (This is almost certainly
different from the dumped raidenk set, despite displaying the IBL
license on the title screen.)
On some boards (both the common dedicated hardware and the older
SEI8904), the SEI0050BU has been replaced with a small daughterboard
with six TTL chips and two PLDs labeled S50P01 and S50P02. A bootleg
set has been observed with a (larger) daughterboard likewise standing
in for a Xilinx PLD.
