+Nandemo Seal Iinkai (Astro Boy ver.)
+(c)1996 1997 I'max/Jaleco
+
+Jaleco game similar to Nandemo Seal.
+It sat at the back of an arcade repair workshop for about 15 years.
+There's an external sound board. No ROMs on it but there's an NEC D78P014 MCU(?)
+and an Altera FPGA and other sound related stuff, plus a Sony CXD1178Q (RGBDAC?)
+
+The game boots here to a message screen and complains and won't go further. 
+Probably the external sound PCB is required to boot up.
+It's missing the special cable so I can't connect it.
+
+Mainboard:
+NS-96205
+
+Daughterboard:
+NS-96206A
+
+Sound: M6295 (on daughterboard)
+
+ROMs:(all ROMs are on daughterboard)
+1.1 - Programs (TMS 27C020)
+3.3 /
+(actual label is "Cawaii 1 Ver1.1" & "Cawaii 3 Ver1.1")
+MR97006-01.2 (42pin mask ROM, read as 16M, byte mode)
+IC6 is not populated.
+IC2 and IC5 have a 0-ohm resistor wired to pin32 (A20 on a 32MBit ROM)
+IC5 has it set so pin32 is tied to ground. So IC5 is 16MBit.
+IC2 has it set so it goes to some logic on the main board (pin 12 of a 74LS244).
+IC2 is dumped as 32M with both halves dumped in byte mode, 00's stripped and then interleaved.
