Haha it's perfectly fine man. I have too many different coding ideas/projects open that I wish would just be done every day so I can finally relax; you're better off letting yourself breathe and taking your time.

*pops out of hat box* Here I am.

Did you know that Gamehacking DOT org apparently has
more than 10,000 GS codes for 007 - TWINE?

A little snippet from the page.

007 - The World Is Not Enough
(Europe) (En,Fr,De) 32M 7F030D3A 2092 codes
(USA) 32M 34F0EE5B 10652 codes


I takes frickin forever to load the page though.

Edit:I feel that it is much more time than its worth,sorry.

Here is a code that someone else made that was already in the custom cheat list I have.

It gives you 99 shots with 0 rounds.
Enable it and hard reset to make it work.

You have to get a gun for all others to become available.
I think it is missing a few from what your list has.
I had to taze a cop to get his gun on the first level to activate the rest,failing the mission. LOL

I just can't get enough time to formulate such a massive code,especially when they are specific to each mode.

It would be like DRS.

I even got an activator for it.

Rear Wing Angle (D-left)
D00A41C0 0002
800B04BB 000x

Rear Wing Angle (D-right)
D00A41C0 0001
800B04BB 000x

I am not sure how to tell if it works during races,or if works at all.
Welp,I tried.

[retroben]

I am ready for the next,hopefully less steep code request.

I just gotta watch the new Simpsons and stuff at 7:00PM,so request soon before it gets too late.

Increasing the rear wing angle should lower the top speed but give more grip. On a real F1 car, they have a button that opens the rear wing, taking off all the rear downforce, which increases the top speed for overtaking on a straight.

I'll test it on the Germany track.

Many thanks...

Edit:
It doesn't work during a race.

The address above is probably used during startup. Guessing there is another memory location which gets set before the race starts.

[retroben]

This is probably another case of seperate address location per level.
I got the wing from the first level in normal race mode.
I also tried looking for a current speed modifier as a bonus,but I couldn't find it.

The wing values in the race are probably ignored after the initial setting.
It could be a seperate address for the wings visual position I am missing.
That would probably not even effect the actual physics,even when
using the other address,because it is being ignored.

This is probably why there is almost no existing codes for that game.


I am eagerly waiting for the next code request.

[Frank74]

If I had a proper debugger that would let me set a breakpoint on the read address of the code you gave, I could make an assembly patch myself.

I found 2 memory locations for the rear wing angle. But neither work during a race. It works when you you restart a race, but thats no use really.

I've read up on hacking N64, and Nemu is the only option for hacking it seems. So I might give it a go, though never used Nemu before.

I know assembly language though, so a debugger that gives an assembly listing would be very useful...

[HatCat]

Yeah Nemu64 is the only option.

There was supposed to be an assembly listing in the Project64 memory dumper, but clicking that button just sets a breakpoint and crashes the emulation thread. So for it to work on PJ64 you would need to play with the build numbers to find which is stable.

Or, you could open up the "R4300i Registers" panel through PJ64's debugger, get the current PC register's value to know the offset into the RDRAM where the current MIPS instruction is being fetched, then you would know where to start disassembling from manually in your head, but you would have to do the work of the disassembly by hand yourself until Project64's assembly logger works again.

[retroben]

As you may have noticed,I have been toying around
with the Banjo-Tooie animation modifers in the meantime.

That is what I do between the requests.

I have no knowledge for extensive hacking,only the basic look for value in general address location and isolate the general offset numbers.

[retroben]

Thought I might share this with the forum.

From what you said on guest grumps about the problem with XBOX and no Banjo-Threeie,and how you wanted a Banjo-Kazooie remake with a smoother gameplay experience.

And in light of coolboyman restoring beta tracks into the ROM,I am the one who found a GameShark code for Banjo-Kazooie that removes the laggy skips entirely.

Here is that particular GameShark code.

B-K Sixty FPS
802808DC 0080

Take note that this is for the original US game.

Now people can play Banjo-Kazooie with a perfectly smooth experience with a GameShark on their N64,or the other way.
It might sadly lag on console.

I also originally found it for Banjo-Tooie.

B-T Sixty FPS
8007913C 0080

It makes Banjo-Tooie look so much better without all the skipping.

To fully understand how it works,it changes the 4byte address to the most negative value in the 1st byte which cancels out to zero skips.

There is also a fan-made Banjo-Kazooie HD texture pack made for emulators.
On a powerful computer,you could use the code with that and the beta restorations,and you would get awesomeness.

Hey Benjamin,
