Dreamcast Widescreen Hacks

I don't remember directly but you can translate most codes in the scheme "to address X write those N bytes: Y". I think I posted on this in the pseudo Saturn thread but I can't find it anymore.

 

That would be correct.

 

I checked a bit and the code to disable panzer dragoon action replay check is:

06002EB0 0009

The first number is an address in memory, and the second is the value to write there. If the address can be linked to a file you can easily edit the files instead applying the code with an AR.

Example for a modification in the ip.bin:
You take x = 0x06002EB0, and y = 0x06002000 is the address where the ip.bin is loaded in memory. So you do z = x-y = 0x00000EB0. At this address z in the ip.bin, you write 0x0009. Since ip.bin is the first 16 sectors of the iso, you can edit it directly.

The same should hold for memory addresses corresponding to the main binary. Although it might be complex to modify the program if the location in memory can't easily be traced down to a value in a file (e.g. dynamically computed).


Someone with skills I don't have could probably turn any AR code into a small ip.bin stub.

 

If you have the pal copy of the game use this code to enable widescreen
F355 Challenge - Passione Rossa V1.001 (2000)(Acclaim)(PAL)

Code:

022C6B7C
00004000

Then chose what camera-hud you want and add those codes too.

 

Just wondering

Are there any custom/modified versions of codebreaker or any oher cheat device which makes dreamcast games ws, that already have all these codes embedded so I don't have to do it manually? Would be awesome if anyone had the skills.. I wish I did.

 

Not at the moment, these are really recent discoveries. I know Codebreaker comes with pre-added codes, and it would be handy to have a modified version with these included (Adding too many codes to one save causes errors in the Codebreaker savestate) but for now I don't think anyone knows how to alter the Codebreaker code to do that. The current list is also by no means exhaustive of the Dreamcast's catalogue, meaning regular updates of the altered Codebreaker would have to be released - that's a lot of work.

I think it's definitely possible, as for how likely it is depends entirely on if there's anybody willing to make the modification.

 

@Roareye That's the reason I use an Action Replay, I got tired of dealing with Code Brakers constant errors forcing me to re enter the codes over and over again..

Action replay just works fine, no matter how many codes you enter, and your savegame never gets corrupted.
So far I have codes for more than 90 games and everything works just fine.

You can find easily a version of AR cracked that works perfectly.

 

Didn't know there was an action replay for Dreamcast. I'll look it up. Are the codes the same or do they need to be modified?
I'll have to find it and rip it to disc, cos I only use real hardware.

 

Yes the codes are the same.

You just burn the action replay to a disc and you are ready to go.

 

Double post.

 

Well alternatively I was thinking a save file for AR or Codebreaker with most codes already added would be a pretty nice thing to have.

Also, when Neuroacid tries adding cheat codes to the GDMenu it would be nice if they could be added via text file or something from PC to make it easier to type out the codes.

Do you know if AR supports the DC keyboard for typing out codes? Would really make things so much easier.

 

Actually, that's the general idea, at the moment I use a simple "cheats.bin" file for testing, which can be easily edited/compiled with a tool called XPDCCC (Xploder DC Code Compiler). Whenever I'm done with the cheat codes implementation, I intend to compile a file with as many codes as possible, so there's less need to spend an eternity entering them one by one in the menu, besides it will also save you some space in the VMU.

Hmm... that's an interesting question, and it so happens that I've been thinking about releasing a loader for it, mostly for people who don't have a GDEMU and want to use CB with japanese_cake's custom bootROM.
So, I could probably also make it load an external cheat codes file and it shouldn't be much more additional work anyway, give me a few days and I'll look into it.

 

Awesome to see we are thinking alike on the issue. This is some great news these features will be implemented eventually. Don't worry about rushing anything out super fast. Take your time. We appreciate all the work you have put forth on this menu.

 

Going to be a bugger and add a few requests lol

PAL - Buggy Heat
PAL - Ready 2 Rumble Boxing
PAL - MDK2
NTSC-J / JAP - Super Producers (Mezase Show Biz Kai)
NTSC-J / JAP - Puyo Puyo Pop Fever
NTSC-J / JAP - Eternal Arcadia (Skies of Arcadia)
NTSC-U / USA - Quake III Arena (The code doesn't work properly and I can't fix it on real hardware)
NTSC-U / USA - Railroad Tycoon (I know its petty, but I want it lol)

 

Quick question: Do you need a master code for Sonic Adventure 2 in the NTSC-J version, or only the NTSC-U?

 

@Esppiral

I have a request for MSR PAL. If we are able to change the camera angel in different positions in F355 it should be possible to move the camera onboard (driver position) in MSR. Can you give a try?

 

Good idea, but you might have to do it for every car. I remember a hack for Project Gotham on OG Xbox that did this. Each cars camera was edited in the game files for this to work, so maybe it is possible to do the same way with MSR?

 

I have another game with bad camera to add to the list. Virtual striker, and I think a far camera exist , because sometimes the game zoom out especially when there are long passages ,but don't know if it s possible to lock it. Also the action replay with integrated codes would be great. I use codebreaker but will surely pass to action replay. I was even thinking to try with my Dreamcast keyboard to put the camera code for f355 because was too long, but my keyboard it s new ,from my collection and don't want to open. I investigated about add codes to codebreaker by PC, but sadly there's no method , although maybe an alterated save file transferred by an SD card to a vmu... Too complex, I have to look for a action replay iso and look at this. Is it slow like codebreaker at the start ?? With the notice "this software is not authorised by Sega ..." . It always takes a minute to boot a game

 

Another idea... Is anyone knowing if it s possible to alter virtual striker textures and audio data? Pes for Xbox with modded textures and supporter real stadium chants was great. Virtua striker really lack in audio, it s an arcade, I know but sounds like sh*¥

 

Outside of the camera alteration, I think you're asking for more than the topic is aiming for Alessio. Altering textures and audio data is certainly possible but requires much more than a Codebreaker code to make work, you'd need to break into the game's code and change it all piece by piece. It's more a mod job than a simple hunt for codes.
