+The address decoding is done by two PALs (IC11 and IC12) which haven't been

+Notes:
+- For sound communication, we are using code in audio/taitosnd.c, which
+ claims to be for the TC0140SYT chip. That chip is not present in Rastan,
+ the communication is handled by PC060HS, which I guess is compatible.
+
+TODO:
+- Unknown writes to 0x350008.
+
+
+Stephh's notes (based on the game M68000 code and some tests) :
+
+1) 'rastan' and 'rastanu'
+
+ - Region stored at 0x05fffe.w
+ - Sets :
+ * 'rastan' : region = 0x0001
+ * 'rastanu' : region = 0x0000
+ - These 2 games are 100% the same, only region differs !
+ The US version has the copyright message twice in ROM though
+ - Coinage relies on the region (code at 0x05ffa2) :
+ * 0x0001 (World) uses TAITO_COINAGE_WORLD
+ * other uses TAITO_COINAGE_JAPAN_OLD
+ - Game name : "RASTAN"
+ - No notice screen
+ - In "demo mode", you get a scrolling screen with what the various items do
+ - No beginning screen when you start a new game
+ - Same "YOU ARE A BRAVE FIGHTER ..." message between levels
+ - No message after beating level 6 boss
+ - No copyright message on scrolling credits screen
+ - Game ends after round 6
+ - There was sort of debug address at 0x05ff9e.w in ROM area :
+ * bits 0 to 2 determine the level (0 to 5)
+ * bits 3 and 5 determine where you start at the level !
+ . OFF & OFF : part 1
+ . OFF & ON : part 2
+ . ON & OFF : part 3 (boss)
+ . ON & ON : IMPOSSIBLE !
+ * bit 4 doesn't seem to have any effect
+ * bit 6 is the invulnerability flag (stored at 0x10c040.w = $40,A5)
+ surprisingly, it doesn't work when you fall in the water
+ * bit 7 is the infinite energy flag (stored at 0x10c044.w = $44,A5)
+ Be aware that the bits are active low !
+
+
+2) 'rastanua'
+
+ - Region stored at 0x05fffe.w
+ - Sets :
+ * 'rastanua' : region = 0xffff
+ - Game uses TAITO_COINAGE_JAPAN_OLD
+ - Game name : "RASTAN"
+ - There was sort of debug address at 0x05fffc.w in ROM area
+ See 'rastan' comments to know what the different bits do
+ - Same other notes as for 'rastan'
+
+
+3) 'rastsaga' and 'rastsagaa'
+
+ - Region stored at 0x05fffe.w
+ - Sets :
+ * 'rastsaga' : region = 0xffff
+ * 'rastsagaa' : region = 0xffff
+ - Game uses TAITO_COINAGE_JAPAN_OLD
+ - Game name : "RASTAN SAGA"
+ - Notice screen
+ - In "demo mode", you get no scrolling screen with what the various items do
+ - Beginning screen when you start a new game
+ - Different messages between levels
+ - Message after beating level 6 boss
+ - Copyright message on scrolling credits screen
+ - There was sort of debug address at 0x05fffc.w in ROM area
+ See 'rastan' comments to know what the different bits do
+ - Different way to handle coins insertion ? See additional code at 0x039f00
+ - Same other notes as for 'rastan'
+
+Note: The 'rastsagaa' set's rom numbers were named as RSxx_37 through RSxx_42
+ skipping RSxx_41. It's doubtful that Taito would reuse those numbers in
+ 2 different sets with different data/code. The names have been corrected
+ to known files names where the code matched.
