Dreamcast Widescreen Hacks

It's universal RAW format. You can use it on both Dreamcast and emulators.

@Esppiral

Man that Dino Crisis game is soooo stubborn. I found exactly the same stuff on PS1 version of the game but not a real zoom/height/width address. Drives me crazy.

 

It's strange, MSR hack doesn't work on my Dreamcast. I use the pal version on my Pal console

 

It may need a master code(?)

 

What is a master code ?

 

Doesn't work for me either

..and I couldn't find any master code for msr:

I think is not needed...

edit:

Legacy of Kain - Soul Reaver v1.000 (1999)(EIDOS)(PAL)
02129FA0---3EF55555
0212A9BC---3EF55555

Tested on a dreamcast. Works. Only slightly clipping and the energy bar is still displayed in 4:3. Overall great work

 

I don't understand why it doesn't work.
I subtracted 2A000000 from 2C107FDC (which is the Demul address) and got the actual Dreamcast address, tried to use it with NullDC's cheat machine that recieves RAW Dreamcast cheats and it worked.
Could somebody enlighten me why it shouldn't work?
How many versions of MSR do exist?

EDIT: Ugh, god knows how many different PAL versions exist:

I may need a cdi of your version or something as I don't see any other way of spotting it.

EDIT 2: Wait, I may be able to find the addresses from online database offsets.

 

Updating all MSR cheats, these re-releases are breaking my nerves.

Metropolis Street Racer (PAL) (v1.009)

Code:

16:9
02106B5C 3F99999A
021111F4 3F900000

Eyefinity
02106B5C 40666666
021111F4 3EC00000

Metropolis Street Racer (PAL) (v1.001)

Code:

16:9
02107FDC 3F99999A
0211253C 3F900000

Eyefinity
02107FDC 40666666
0211253C 3EC00000

Metropolis Street Racer (NTSC)

Code:

16:9
0210A01C 3F99999A
021146FC 3F900000

Eyefinity
0210A01C 40666666
021146FC 3EC00000

I doubt there's any other version of the game.
If these don't work then there's somekind of memory allocation error in DC Emulators.

 

Its great that you guys are keeping this going!

 

thanks, added to this wiki: http://www.elotrolado.net/wiki/Formato_Panorámico_en_juegos_de_Dreamcast

 

Yeees, the second one works for me:

16:9
02107FDC 3F99999A
0211253C 3F900000

Thanks

 

There's only one place that the code is not working correctly (well it's simply reduced height).
That DEMO mode on the intro, but I guess nobody cares anyway, it does not affect any of the gameplay modes.

 

Thank you, it works for me

 

What a relief, I was seriously brainstorming what could be going wrong.
I'm curious to see how the Eyefinity one works on real hardware, it pulls ALOT of extra polygons and textures.
Dreamcast's PowerVR supports hardware culling right?

 

Just tested with the infinity code:

Eyefinity
02107FDC 40666666
0211253C 3EC00000

In singleplayer mode everything is fine. No clipping no slowdowns. In racing mode with 5 opponents I had some slowdowns running with ~20fps (weather rain) in situations when 2-4 cars were in front of my car. By switching the camera view I could reduce the slowdowns....and still no clipping. Overall good performance I would say. Dreamcast is a beast

 

@VIRGIN KLM If memory serves me well, yes it does.

Msr ingme menus run at 60fps, if we are lucky enough we could find a 60fps hack alas sonic adventure.

 

PS1 doesn't. You have to hope that the game's engine doesn't call many polygons so you have a headroom to include more on the viewport.
There are games that have some slight issues but there is just one game that does an incredible thing, on the wrong hardware.
Smurf Racer will calculate real-time how many polygons it will call depending of the value you set on the width/height/zoom.
It will try to render EVERYTHING you tell it to render, as far as you want to go.
This makes the widescreen hack a bit resource costy in a couple of random places, with some very thin chances of hanging.
Setting it to Eyefinity it will go as far as trying to call every little thing present in the map at once, which causes constant slowdowns and most of the times it will call sooo many objects to draw that the memory will leak into kernel ranges and the game engine will still go on and allocate more and more memory for it even after the console hanged until it overwrites system memory which will trigger an extremely rare emergency system reset followed by a PFEAR booting sequence.
.

Resetting your PS1 fixes the issue like nothing happened though.

I wish we knew that stuff back then, you could effectively create an exploit with that game.

 

yes, by the nature of TBDR, Tile Accelerator handle this.

 

Any new widescreen patch? =)

 

60FPS? I'm in!!
Hey guys KabutoKun here, new member BTW.

As I saw some 60 FPS cheats being posted (even for some games I have already tested before and I have not posted anywhere, uff), I think this is the right place to finally post some of them.

These cheats are in ChankastCheater/codebreaker format, to test them in DEMUL replace the first 2 characters of the address with "2C".

;Sonic Adventure International [HDR-0043] [V1.003]
60FPS-A-Framerate 0075683C 00000001
60FPS-B-Speed 00756844 00000001
30FPS-A-Framerate 0075683C 00000002
30FPS-B-Speed 00756844 00000002

Sonic Adventure: I found this one a long time ago. We have to change the value for 2 addresses, Framerate (this one changes the framerate from 30 to 60, but using only this one makes the game run at double speed) and Speed (corrects the gamespeed).
I added both with 30 and 60 FPS values, obviously you have to enable both Framerate AND Speed for your desired FPS.
Normal gameplay at 30FPS have both values with "2", game menus or Twinkle Circuit (which actually runs at 60 FPS) have them both with "1"; while playing cutscenes the Framerate has "2" and Speed has "1".

The problem with the Sonic cheat is that the cutscenes run at double speed, we should use a conditional cheat to detect when we are really playing a stage or if a cutscene is playing (I use ChankastCheater and I don't know how to use conditional codes with it).

;Fur Fighters NTSC [T-8107N] [V2.001]
60FPS 003138C8 00000001
30FPS [Default] 003138C8 00000002

;Fur Fighters DEMO [8D-0008-50] [V1.000]
60FPS 002D9B10 00000001
30FPS [Default] 002D9B10 00000002

Fur Fighters: normal gameplay runs GREAT, but the rolling demo/autoplay, some cutscenes actions and items rotation are running at double speed.

;Grandia2 NTSC [T17716N] [V1.001]
60FPS - Battle Only 02300010 00041400
30FPS - Battle Only [Default] 02300010 00241000

Grandia 2: It NEEDS a conditional cheat, if you start a battle with the cheat ENABLED then the battle screen is not rendered, you can test the cheat by enabling it AFTER you start a battle. I have a cheat to make it run at 60 fps in field mode too, but for some reason it runs at double speed, unlike the battles that run how they should at 60fps.

;Metropolis Street Racer SAMPLE DEMO [MK0001] [V0.800]
60FPS-A-FPS 00137F0C 00000001
60FPS-B-SPEED 021539AC 42700000
30FPS-A-FPS 00137F0C 00000002
30FPS-B-SPEED 021539AC 41F00000

MSR: This cheat is only for the DEMO (one of them, check the ID) but can be easily ported.
As @Esppiral pointed out, the game menus run at 60FPS, just check the changing values with cheat engine or similar. The speed address is a float: 30.0 at 30fps and 60.0 at 60fps.
Sadly the cheat is not perfect as it heavily affects the cars handling, so you have to get used to it.

These are some Dreamcast games I have already tried but then they run at *DOUBLE SPEED* at 60 FPS (speed modifier/s are needed):
- Resident Evil 3
- Skies of Arcadia (what a shame...)

I already have Demul v.0.4.9 (the version with the debugger) but It's a very old build and it does not boot the games I need to test. nullDC debugger has never worked for me in any way. I am using IDA to check some things when I have to but I REALLY need runtime breakpoint functionality with the dreamcast emulator. Before the long pause in development that had Demul, the source code was released around 2013, right now I can't even try to recompile it but maybe this updated version has a working debugger, take a look at GitHub guys.

This is all I can say for now, I hope you guys take seriously the framerate unlock as you did with the widescreen hacks, thanks a bunch for those.
PD.: Good to see you around @VIRGIN KLM

 

And another saviour has arrived!,

THanks for those codes =)
