Hmm, maybe im just borking the binary.

If I remember correctly, some sort of low level hash check gets either done to the 1st read or ip binary.

I'll continue to stab at it.

Definitely looking forward to any updates. I am sure even that even if you don't succeed immediately you will find out interesting stuff to tweak or hack if you keep going. Keep up the good work!

Thanks!

Yup i have been documenting everything. Most of it is known already but a good portion of that knowledge isnt public!

So it will be eventually.

UPDATE: July 21st 2014.

So I made a ton of reference changes in 1st_Read and in some motion data files.

Ive gotten some weird results. Things like Ryo doing the wrong animation when buying a soda (kind of like LanDC's evi soda machine video). SO right now its a trial and error procedure. I am also working on finding differences in RAM when Wang gets on and off his bike to see if I can make Ryo perform the same.

One quick work around I am testing now is to see if I can get Ryo to trigger that animation of Wang getting on the bike.

Maybe Just Maybe, Ryo will get on and stay on the bike.

Also, some people are mad on Facebook that I do not provide any photos or anything about what I am doing.

I know that looks suspicious, but its just a matter of me being lazy and not caring to show it in action. Id rather spend that time developing the method itself.

So as of now we have three potential solutions.
1. Pivoting player control from Ryo to Wang.

2. Adopting Wang's animations into Ryo's user controllable AI

3. Swapping the motorcycle with a bicycle and tweaking the motion data of the motorcycle to make it slower and chain load Wang's bike riding animations.

Number 3 was my original idea that actually sort of worked. However, to dump Ram I was using a hardware method that busted my mother board. (Thank you to the moron on dreamcast.eu who cursed me out on that when it was his mathmatics)

Number 2 is my primary focus as itll make it as authentic as possible.

Number 1 is wishful thinking.

Both number 1 and number 2 require a good amount of hacking in 1st_read.bin

Kyodai! I actually found some useful changes from Whats Shenmue to the retail NTSC shenmue that might help this out. I might be combining the two files into one ultimate 1st_read to see if I can make my own potential loop holes in the retail version.

I swear to god I will get this working one day. Even if it takes a life time.

Thanks!

Riding the bike has been something I wanted to do since I first heard about it.

Also, I love bike riding in general so its nice to adapt that into my favorite world :)

The problem with this mod is that its just a pain in the ass to figure out lol. Shenmue is usually an easy game to work with since alot of variables are human readable when editing. Plus, we have an awesome modding base here, although it has died down somewhat since the early 2000's.

LoL your avatar. I actually know miley cyrus outside of her popularity career. Shes really not that bad of a person.

Update:

Continued doing code searching to pinpoint the correct RAM calls when Wang gets on the bike.
Also, working on motion.bin to trial and error out a solution.

Not too much is different from my last update. Just trial and error many many times.

Update:

Im setting the first alpha release for December 25th.

Post from Facebook:


Bike Mod Update:

Shenmue Bike Mod will have its first release on December 25th.

I will be supplying modded disc images and the instructions to a few select people.

The release will also include video footage for everyone else.

It will be released publicly once the testing phase is over and all bugs are ironed out.

I broke 3 different Dreamcasts making this mod so you all better enjoy it! lol. Had to sodder stuff to do some side channel hacking and dumping. Not fun.

I have spent almost two years making this mod and I really hope it will bring Shenmue closer to its roots.

The methods performed also shed some light on how the Radiant AI system works in Shenmue 1. Some of these procedures might even let us create our own AI day/night cycles.

Once it is done, I will be looking into seeing if we can get it to work in Shenmue 2.

A HUGE thanks goes to the unnamed AM2 Programmer that shed some light to me on how mapinfo and motion.bin work

For technical information, feel free to check out my development thread:

Amazing Shengoro. I'm waiting this very mod.
You know, I'm having a lot of fun with you mods. I finally make one of my dreams true; go to the war ship in the harbor, lol.

Alrighty, as promised. Here are some teaser images of my new approach.

Custom debug value allowing for player to control Wang's AI. Here we have WanRyo about to hop on the bike.
Image

Here we have the first camera pivot as the bike animation happens, that doesnt exist.
The model for Ryo/Wang disappears. I do not know why this happens yet.
Image

Here we have the final camera pivot of WanRyo on the bike.
Image

Here we have WanRyo riding to the end of Dobuita.
Image

Currently, the bike floats and Ryo's model dissappears.

With this approach, I do not know if its fixable. But I'll keep looking into it.

For now, thanks for being patient.

Would it be possible to just create a model of Ryo riding the bike? Like having Ryo on the bike be all one character and the wheels act as his legs sort of, of course that would look strange during A LOT of scenes, well it would be hilarious at least.

Imagine a Bicycle bound Ryo trying to find Chai and doing a kick with the wheels.
