Shenmue 1 and 2 widescreen hacks Dreamcast

[ShenSun]

I'll try to summarize and explain the best I can how to use it on DEmul and NullDC using Cheat engine.

Cheat Engine Download: http://www.cheatengine.org/downloads.php

Prepare emulators: choose
In DEmul: Config->Video-> aspect ratio: 16:9
In NullDC: Options->PowerVR->aspect ratio->Stretch
Start your game.
In Cheat Engine open process with your emulator
Click "add address manually" and add address according to your game and emulator from list below,
also make sure that type is set to 4 bytes!!
DEmul:

Shenmue (PAL)
2C231EF8

Shenmue (US version)
2C230250

Shenmue Undub
2C231EF8

Shenmue 2 (EU version)
2C31186C

Shenmue 2 (JPN)
2C30D67C

What's Shenmue (JPN)
2C20BB68

NullDC:

Shenmue (PAL)
1C251EF8

Shenmue (US version)
1C250250

Shenmue Undub
1C251EF8

Shenmue 2 (EU version)
1C33186C

Shenmue 2 (JPN)
1C32D67C

What's Shenmue (JPN)
1C22BB68

Initial value should be "43A00000", if it's not - Right click on address and choose "show as hexademical"
Change value from "43A00000" to "43800000" enjoy your game !

Here's a Cheat Engine file that may save you a bit of time when applying this fix with Demul. You can easily toggle between the default Letterbox (4:3) mode and Widescreen (16:9) mode by clicking on the value column of the related version.
This works with: What's Shenmue [JP], Shenmue [EU, US, JP], US Shenmue [JP], and Shenmue II [EU, JP].

This is a simple way that may save you time when applying this fix with NullDCCheater since Cheat Engine seems to be causing NullDC to crash for some reason on some machines.
You can easily toggle between the default Letterbox (4:3) mode and Widescreen (16:9) mode on the fly.
This works with: Beta Shenmue, What's Shenmue [JP], Shenmue [EU, US, JP], US Shenmue [JP], and Shenmue II [EU, JP].

You need to follow those steps to get things to work correctly:

• Download this version of NullDCCheater from this link and extract it.
• Rename NullDC executable to NullDC.exe, and run it.
• Load a Shenmue disc and wait for the game to start.
• Run NullDCCheater and it should recognise your Shenmue game. if the game wasn't automatically recognised then you have to manually choose the right version from the dropbox menu.
• Select Widescreen or Letterbox mode.
• Click the cheater activation button.

Thanks for the instructions! I set the value correctly but it crashes NullDC when I am changing it. I am using the English Dub of Shenmue 2.

Strange.. have you tried it in Demul? also does it also crash on original non modified Shenmue games?
upd: just tested this one https://mega.nz/#!HNETzDgQ!E_hoqpOIUNNX ... FBVKRNu7HQ
on different revisions and computers it's all works, no crashes
masterchan777
cool! It's much more convenient, can you also add nullDC codes? than my method can be deleted.

[Anthony817]

Yep, crashes on Shenmue 1 regular unmodded game.

I never mess with Demul because it is not very user friendly compared to NullDC. I literally maybe have ever used it 1 or 2 times successfully. I guess I should probably just try it again.

Edit: Yeah that is my mirror I uploaded of the one for ODE's and Emulators.

[Radar]

I wish i knew why it crashes. completely fine on my side does it also crashes for anyone else here?

[Anthony817]

Well I am even using the NullDC with Shenmue fixes, so I reckon it is the best version for the games. It sucks we have to use 2 different discs to boot codebreaker codes on backups with discs. You must first boot with the bootloader disc, then insert a cracked Codebreaker disc, enable codes, THEN finally put the 3rd disc in when you are ready to boot it, Ziming told me his GDEmu boots the iso of codebreaker fine, so if those of us that still use discs it is kind of a pain.

ok. try to use NullDcCheater, here is instructions
viewtopic.php?f=37&t=47444
use codebreaker adress i.e this one "0231186C 43800000" for Shenmue II

The file only works with Demul atm, had a quick look at NullDC and it seems to be crashing even with the nulldcCheater for some reason, will give it another look and report any findings.

Small update... The original widescreen codes actually added twice as much width to the screen as they should have. You may have noticed this in the screenshots on the first page, Ryo was thinner than he should have been. Here are the corrected codes:

Shenmue 1 US: (Updated 2015-10-25)
02230250 438E38E4

Shenmue 2 EU: (Updated 2015-10-25)
0231186C 438E38E4

This is the exact width it should be if you're going from 640x480 to 720x480 and want to maintain the same aspect ratio. Only change is the value part of the code, which is controlling the width. This helps reduce pop-in even further, since you have less extra area to notice it. :-)

16x9 is only 12.5% wider than 4x3. The code was crushing the horizontal display by 25%. The new code crushes it by 12.5% instead. This was my fault for eyeballing it, I hadn't bothered to convert the hex numbers to floating point to see what they were.

[BlueMue]

Why actually 720x480? Does is have something to do with the correct streching ratio when you use this on TVs? Because 480p with proper 16:9 aspect ratio actually has a resolution of 854x480.

I finally got around to try it earlier today. I played Shenmue II and I got it to freeze during the cutscene with Ren and his gang at Pigeon Park on one of the camera angle changes. Something strange going on there. The little bag of money or whatever that Sam and Larry throw and catch was missing.

do you know what the correct Shenmue 1 PAL code would be?

do i just need to change the second line of code to 438E38E4 instead of 43800000?

@bluemue
i will do a full playthrough with these codes at some point, so i'll find out if there are any bugs.

p.s. i'm a bit unsure about the new codes, it seems a bit too fat, but i can't really be sure. the side pop-in is almost completely gone, so its a good option for people who find it too distracting with the other code. a nice compromise as it were.
