Awesome Thank You

 

Yes I already knew those are already posted Anthony, but those HEX (FIND / REPLACE) codes will not work on Codebreaker. They must be posted as CodeBreaker codes, in order to work with it. Thats why I am requesting those codes.

Awesome Fluffymadness!! I will try it! I probably didnt noticed since it says ZERO HUNNER xD lol I tought I even reviewed all the 50 pages here. Thanks again Fluffymadness!!

 

Is there a quick tutorial on how to edit the CDI image with these hexes? Really interested in playing some of the games in widescreen, especially Tokyo Xtreme Racer 2!

 

Yeah I'm looking for this too.

We have to replace this in the 1st_read.bin or it's available only with gameshark ?

 

@Gizmo613
just open the cdi image with any hex editor of your choice.. And then select search and replace from the menue.

eg. for Tokyo Xtreme Racer 2 just, select search and replace all.
The code to replace for Tokyo Xtreme Racer 2 occurs at 4 places in the cdi image. So you have to replace all four of them for the patch to work.

Widescreen 16:9 ( 4 TIMES)
Code:
FIND
ABAAAA3F
REPLACE
721C4740

After you've done that, you can simply save the image to play in widescreen.

You can use flex hex for example. In the menue select Search->Replace-> Find what:hex bytes
Then enter the value
AB AA AA 3F
Replace with:
72 1C 47 40
Then press replace all.

@fafadou
The 1st_read.bin is simply a part of the whole cdi image. So you can just do a simple search and replace with the hex editor, to replace the values of the files.
For a gdrom dump, you have to open one of the tracks in the hex editor. I think it is usually the largest one.

 

And it will still be ok to burn them to cd-r?

 

It should work fine after burning https://assemblergames.com/threads/dreamcast-widescreen-hacks.58620/page-47#post-937710

 

Alright! I'll give these a try when I get home from work. Thanks for your help.

Edit: I noticed that widescreen hex is for the EU version of TXR2. I have the US version. Has the US version been found?

@Esppiral
Any chance you will be able to find the codebreaker codes for these? My physical dreamcast library is not very large, but with the games I do have physically, I would like to be able to play them in widescreen.
Thanks!

Power Stone JP
Gun Spike JP
Dino Crisis US
Capcom Vs SNK US

 

@Esppiral
When you get the chance to get these hex patched:
Skies of Arcadia US
Tokyo Xtreme Racer 1 & 2 US
PowerStone 1 & 2 US
Evolution 1 & 2 US
Marvel vs Capcom 1 & 2 US
Grandia 2 US (widescreen plus 60 fps battle)

Thank you

 

I will only hack Pal or Japanese games, the reason is simple, if a Pal game supports VGA and 60 hz + multilanguage (english, spanish, Italian, french and german) I don't see a reason to hack the US version since it usually only contains english , instead I prefer to focus on hacking other games rather than the US version since the EUR version is serviceable enough.

The reason to hack japanese versions is obvious.

The only reason to hack the US verion of game is if the Pal version does not contain english ( very unlikely) or the pal version does not support VGA or 60 hz.

Very good find, it work on PAL M5 (FR) version too, no modification required.
A big thanks for this

 

...or because the person doesn't want to download the PAL version when he could just patch the dump he made of his own NTSC-U GD-ROM. People should ideally be able to patch their own games, not just bootlegs they downloaded from random sites.

Note: I'm not saying you're obligated to patch all game regions, since you're free to spend your time however you please, but it's also not true that patching US releases is pointless when true Dreamcast enthusiasts are going to have their own original copies that they'd like to run in widescreen.

 

Fair point, anyway most of these hex hacks are actually "region free" in a meaning that most of the time they work regardless of the region of the game.

That's not the case with CB or AR codes most of the time.
