Ugetab to the rescue

[ReyVGM]

Hello ugetab.

Since you appear to be the most experienced one (at least when it comes to hacking almost impossible stuff) and after trying for months, I decided to finally ask you yet again for help.

Remembering the wonders did with the SGB borders and finding that buried Castlevania Legends soundtest, I have to ask you if you could find the NES Wily & Light No Rockboard credits screen.

For years people have tried to achieve the credits screen and for a long time it was believed to be a myth, until I saw images of it on a Japanese page that proved them to be real.

According to the Japanese page in question, you have to play the last map in Battle Royale mode and make the other players go bankrupt. But I've tried it (and many other combinations) and the credits just don't appear.

So I guess the only solution is to see if you can cook up a code that triggers the credits screen, either as soon as you start the game or as soon as you finish the last map (or any map, as you can select them at will).

Anyways, if you need any more info, let me know and I'll provide it and thanks in advance if you decide to tackle this.

I tried looking through the game, but it doesn't look like there are credits to be had, on a somewhat cursory inspection.

I wouldn't count on that screen shot being accurate, personally.

[ReyVGM]

Oh the credits are there. You can see the text if you look with a hex editor ( http://www.romhacking.net/forum/inde...ic,9563.0.html ).

As for the Japanese page where I saw the pics. He has every Famicom ending there, so I doubt that's going to be a fake one.
I tried contacting him to see if he can provide more info, but I sent the message in English so I doubt he will reply.

End Courses Quickly (Player 1 is the 'official' winner. Just don't 'Randomize' to win.)

Always View Credits After Beating The Game (This is normally accomplished by achieving 70% or higher on property ownership/buildings, which is shown at the ending stats board. There's a little Japanese left in the English translation, but only the 1 line)
AEXXNGTG

End Credits(First try):
Pick Wily for P.1
Choose Map 4
Go into a Bankruptcy game

Set the following in RAM(This is the 'Objective' data for the stage):
4D0 = 99 (P.1 has cash)
501-50F = 8E (many spaces with wily's property, all upgraded)
540-54E = 86 (same spaces are owned by wily)

Go through a turn with this set, and you'll get the credits

Jeez ugetab, you are seriously the best code hunter that ever lived.

How did you figure out the whole 70% thing? I didn't even have to use the codes after you gave me that info!

Thanks, you are the best!

He's like a code wraith.

[ReyVGM]

Indeed!

To achieve the end result, I did the stuff mentioned in "End Credits(First try)".

2 save-states made is a simple matter to get credits vs not.

1 got the ending after the ending dialog, 1 didn't. Both were saved at the final line of ending dialog.

Copying 0x100 byte sections(excluding 0x100-0x200) from 1 to the other would eventually match/negate the effects each save-state had(lest it be in 6000-7000 onboard RAM). I copied between 0x0 and 0x100 and succeeded, so it was easy to find what did the change from there.

A look at the value, and the time when it was written told me it involved the end info. Since the value matches the percentage complete for player 1 in several cases, I figured that's what it was referencing.

Cursory Debugger work on the read showed me 70 in hex(or higher) being tested for, so putting it all together, the completion percentage had to be 70 or higher for player 1 when the game ended, and that was pretty much it. The code makes it test for 0 or higher.

I couldnt understand any of that but its impressive none the less. I'll thank you ahead of time as I plan to play and beat this game in the future thanks to your hacking and cracking skills. Thanks!

[ReyVGM]

It was kind of stupid of me to never try to achieve a high property ownership after trying for so many months. I guess I was so fixated with the conditions that Japanese page told me that I wasn't letting other possibilities in.

[ReyVGM]

You know in The Matrix how they were so used to seeing binary code on the screen that they actually just saw images?

That's ugetab with a debugger

I think Ugetab took the blue pill.
