What does this mean?

[ReyVGM]

Hey guys.

I'm trying to get a NES PAR code to work, but I don't know what the author means. Here's what he said:

"if you want a slightly different ending sequence where you haven't married Felipa yet, set the 10 bit of byte 7a to 0(or the whole byte.) "

I don't get how to construct a code from that description. Does anyone know?

[nolberto82]

Bytes only have 8 bits.

[ReyVGM]

Yep, I know, but I still don't know how to construct a code from that. I don't use hex editors to edit values.

[nolberto82]

What the author describes doesn't make any sense. Maybe is the byte before 7a. What game is it?

[ReyVGM]

Columbus - Ougon no Yoake for the Famicom.

Here's the FAQ where he has the codes. The codes are on the bottom and some don't make sense to me either:

I think what the author means is bit 4 of 7a which is 0x10 in hexadecimal.

[rimsky82]

Perhaps he meant it in binary. 01111010 to 01111000, or 0x78.

Edit:
After reading further down, I see this table:

7a-01: talk to old man in E Barcelona graveyard
get golden ring
7a-02: ????talk to someone in Drema
get crystal
7a-04: talk to old man in Dream Town
get cloud clothes
7a-08: talk to flame in the Vienna hidden room
get black gem
7a-10: talk to Felipa when you have the golden ring
+10 fame, and she is your wife
7a-20: talk to first hooded man in Dream Town castle
get the Fire Mark
7a-40:
7a-80: talk to the first hooded man in the Light town castle
get the Wind Mark

...which would signify that he meant the fifth bit (from the right) of the byte stored in (ram address?) 0x7A. (00010000).

I believe that is also what nolberto said, that I misunderstood at first.

[ReyVGM]

Ok, so what should the code be like then? 007A:00?

[nolberto82]

If you don't want anything within that address then it should be 007A:00. Otherwise you can do 007A:EF which would leave bit 4 as 0 and the other bits as 1.

Ah, got it. Thanks!
