+ Raiden (c) 1990 Seibu Kaihatsu
+ Raiden (Alternate Hardware) (c) 1990 Seibu Kaihatsu
+ Raiden (Korean license) (c) 1990 Seibu Kaihatsu
+ Raiden (Taiwanese license) (c) 1990 Seibu Kaihatsu
+
+ driver by Oliver Bergmann, Bryan McPhail, Randy Mongenel
+
+ The alternate hardware version is probably earlier than the main set.
+ It looks closer to Dynamite Duke (1989 game), while the main set looks
+ closer to the newer 68000 games 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.
+
+ Coin inputs are handled by the sound CPU, so they don't work with sound
+ disabled. Just put the game in Free Play mode.
+
+ The country byte is stored at 0xffffd in the main cpu region,
+ (that's 0x1fffe in program rom 4).
+
+ 0x80 = World/Japan version? (Seibu Kaihatsu)
+ 0x81 = USA version (Fabtek license)
+ 0x82 = Taiwan version (Liang HWA Electronics license)
+ 0x83 = Hong Kong version (Wah Yan Electronics license)
+ 0x84 = Korean version (IBL Corporation license)
+
+ There are also strings for Spanish, Greece, Mexico, Middle &
+ South America though it's not clear if they are used.
+
+ One of the boards is SEI8904 with SEI9008 subboard.
