Super Famicom/Snes games PCB Question
Hi,
this question was raised in other forums, also, and i almost solved, but I want to start the topic here also, to solve the doubt.Some time ago, I bought Hagane and Wild Guns, japanese Super Famicom Version.I opened the case with gamebit screwdriver, and the boards are obviously legit..surfing on the web, I realized that there are some differences between us and jap pcb:
Wild guns jap is mounted on a SHVC-1A0N-20 board, the us version is on a SHVC-1A0N-30 board..the cic is D411A in the jap version, and D411B in the us version.
Hagane is mounted on a SHVC-1J0N-10 board in the jap version, the us version is on a SHVC-1J0N-20 board..the cic is D411A in the japanese version, D413B in the us version.
In other forums they already told me that in normal that some japanese games mounts different pcbs and cic confronted to us versions, and by myself I found a pcb picture of hagane jap, and it is on a SHVC-1J0n-10 board like mine..I have never found a pcb image of japanese wilfd guns.
I would like to ask to the experts here if this is normal (i think so, I have found various post around the web, and I have read that many jap games mounts different boards than us version) and if there is a database of the games that mounts different pcbs in the different versions (jap/us/pal).
Thanks in advance and sorry for my bad english

You probably already concluded this elsewhere, but your games are authentic because the ROM chip is a Mask ROM and it has the game's Nintendo product code stamped on it. Wild Guns is 4W, Hagane is KL. (SNS-AKLE-USA for example)
I'll also translate the PCB code for you. Using Hagane USA version for reference.
SHVC-1J0N-20
SHVC = console. Because the US SNES and Super Famicom are the same console internally, Nintendo never renamed the PCBs.
1 = One ROM chip. Some SNES games can use two or even three ROM chips, which will be reflected in the PCB code.
J = HiROM mapping. The alternative is A for LoROM. Sometimes this code is used to denote co-processors instead.
0 = Zero SRAM (and therefore no battery). This number increases depending on how much RAM is being used. 16K, 64K and 256K are common sizes.
N = I think this is for whether the game uses the MAD-1 decoder or a 74xx139, but I'm not sure.
20 = PCB revision. The higher the number, the newer the board is. Sometimes the layout is revised, that sort of thing.
I hope this puts your paranoia to rest.
