Dreamcast Widescreen Hacks

Request for a widescreen codebreaker code for Vampire Chronicles For Matching Service NTSC J.
Can anybody help with this one?!

 

It is a pure 2D game, highly unlikely to get widescreened

 

@Esppiral : Probably you are borried with the shenmue III actus but have you seen my post ? How have you inject directly the widescreen hack directly on the games. I want to do it for grandia 2. Sorry if you have already give the issue.

 

You still have the HEX code for Tony Hawks Pro Skater 2.
I only found a version that you said to be for a test with a lot of clipping.
Did you have another code for this game or just these code with Clipping?

 

I didn't found a render fix yet for thps2

 

@Esppiral
Is it possible to convert existing widescreen Codebreaker codes from one region to another?
Say both Cannon Spike NTSC U and Power Stone NTSC U to NTSC J?

Thanks

 

Yes, but you need both of them so you can find the corresponding offsets in both releases.

 

@Aleron Ives : have you tried to add the widescreen hack directly in your amazing release of PSO et PSO V2 ?

 

There is no widescreen hack for PSOv2 yet, so that's impossible. Adding the V1 widescreen hack is also impossible, because one of the two patches targets a random child value somewhere in memory, instead of patching the assembly in the game binary that generated the value. Only the game binary exists in the game files, so the widescreen hack must patch only values within the game binary in order for an image with the widescreen hack included to be possible.

Code:

02548E84 <--- not a valid 1ST_READ.BIN offset
43D20000

 

You could add a small code snippet to the IP.BIN to do the patching once the game is running. @yzb37859365 might be able to help with that.

 

That approach might work, but it still assumes that the value of interest will always be in the same location, which isn't necessarily a safe assumption to make. Patching the game's executable is a much more reliable way to handle it.

I fear that doing widescreen in PSOv2 will require extra code, because that was the case with PSOGC.

 

I don't understand what you're talking about. If it's PSO V2, the main program is compressed and encrypted, and the original 1st file is just an overfile.

 

In the dc-talk release, it's unencrypted, maybe @Aleron Ives could use that bootbin as a base?

 

Thinking out loud here, seeing PSO supports serverside upgrades/patches, perhaps it's possible to get a 16:9 hack loaded when connecting online? @BlueCrab are my thought possible in theory?

 

Hi friends. This widescreen business is truly great. I was wondering.. Is it possible to cook in the black bars fix for Street Fighter 3 3rd Strike into the cdi? I saw some Shenmue stuff that seems to work.. No idea on how I would do this. Is there a quick way of doing it? I don't have access to a keyboard (easily) from my media center so I'd like to you know.. Avoid cheat engine and I'd really like to just get rid of the black bars. If this is not possible that's cool too.. If anyone is up to the task OR can point me in the right direction on what programs I potentially need to fix up a CDI, I'd appreciate it.

EDIT: @Esppiral, I found a post here that said to just open .CDI in hex editor and replace the codes in there. But when I search for your 3rd Strike codes for Dreamcast in the .CDI none of them are found. Are those codes for PAL or NTSC? I have tried searching like this: 02E18DA0 and like this: 02 E1 8D A0, nothing found. I hope you can help.

 

I was talking about the existing widescreen hack for PSOv1, which uses 1ST_READ.BIN as its main binary. If somebody makes a PSOv2 widescreen hack, you are correct that 1ST_READ.BIN will not be the file that needs patching. The MAG94 cracks allow you to boot V2 with an uncompressed binary, so it's easy to add a widescreen hack to the image, provided it only requires changing values within the game's executable. The problem is finding somebody with the expertise required to create a widescreen hack.

In theory it would work, but nobody has written a patching program for V2 yet. One exists for GC, though. I should probably try applying the GC widescreen hack as a server-side patch to see if it works.

May I ask why the new values are different for V1 and V2, when the original values were the same? According to Esppiral's post, you should multiply by 0.75, so it looks like your V2 values are correct:

0.85 / 0.75 = 1.1333333
640 * 0.75 = 480

It looks like the V1 values create an aspect ratio of 2.03:1, instead of 1.78:1?

 

Nice job on the codes @megavolt85!
