Some of you might remember my Doom on Super Famicom thread from a while back. Well, a couple of weeks ago, I finally got my hands on a mint condition version of the Japanese version of Doom 64. I haven't noticed as much changed with this version story-wise, As the instruction manual follows the english one pretty much perfectly, bar a few typos (want some Health Portions? Or how about Rediation Protection?). Other than that, there are two things which have been changed with this version.
Messages are in Japanese.
This is pretty much expected, considering it is a Japanese game. I don't know how much the messages are changed though, since I don't know too much Japanese. Interestingly enough though, all intermission screens and level names are all still in English, and unaltered.
All blood splatters are now green colored.
Now here is something that really puzzles me. While all blood splatters in the game are now recolored green, all of the blood that is from an enemies death animation is still red (It is really comical to see green blood come flying off the Cyberdemon and then seeing him explode in a cloud of red blood). Even all the decorations (hanging arms, severed heads on sticks, blood puddles on the floor, etc.) are also still colored red. However, there is more that puzzles me here. On the front of the box (scans here) there seems to be some kind of warning about something to do with blood (血, or chi, is Kanji for blood I believe) on the cover. Also, all through out the instruction book, and on the back of the box, there are bullet holes with RED blood coming out of them.
Now, Gamebank (Who handled this Japanese port) also ported Hexen on the N64 to Japan. In that game, ALL blood is green. They even recolored sprites to have green blood. But, according to Gamefaqs, Gamebank released Doom 64 BEFORE Hexen 64 in Japan. Maybe Gamebank was porting both at the same time, and accidentally put green blood in Doom 64. This is just a theory however...
One more technical thing, When saving my game to the controller pak, the Japanese version picked up on my previous savegames from the US version. Does this mean that both versions maybe use the same wad (if that's how Doom 64 works, considering it's a cart) with only the data changed for the Japanese version to display the two things mentioned above? That's up to you to decide. ;)
