Sega Saturn Widescreen hacks (Panzer dragoon Saga POC)

@paul_met:

Tomb Raider NTSC with the 'black border fix' shows like this in 4:3




If the game hacked is already 352 pixels horizontally, then what is the vertical resolution?
Is it a 4:3 proportion?

 

Vertical resolution is 224px.
Find in the game any circular elements and you will see whether keeping AR or not.

 

ynoS XSP, can you check an issue in Tomb Raider hack?
On the splash screen of level loading appears some graphics garbage on the right side of the screen (on the emulators). But the garbage does not appear immediately, only after the restart the level (when the heroine dies). Can you check it on a real console?

 

I will check it today and report back later.

 

@paul_met :

Yes, you are right.

When you die and restart the level, on the right side of the splash screen appears a strange vertical strip.

Here are 2 examples:





But I don't think it's "garbage", I mean, it looks like a portion of the last screen where Lara was when she died.
So, my guess is the splash screen is smaller than gameplay screen and that strip is video-data which is not cleared/updated?

 

Is there somewhere a list of 3D Sega Saturn games?

 

SEGA SEGASATURN SEGA TP T-382 T-38202G V1.00219981119CD-1/1 E J ELANDOREE

(Elan Doree) (J)

Code:

800A69F1 c000

Initial value 256 (float big endian.)

 

Lovely looking game this is.

 

Never saw this game before. Looks interesting.
==================================
Widescreen for Elan Doree (hex code):

Code:

File: "0.BIN"
(Offset / Value)
F84 / 2762
F86 / D57B
F8C / 1458
1176 / C000

 

I agree this looks cool. I looked on youtube and there was an arcade version also. Not sure if Saturn port added anything extra. I'll research this if I can.

The game still looks a bit cramped at 16:9, how does it play? Would 21:9 work too or would that turn into fireball fests?

 

You can check it yourself if you reduce the value of "C000".

 

If you want to try 21:9 aspect ratio

try this.

Code:

800A69F1 9100

 

@paul_met

Can you look if you can patch this one please?

It seems to suffer from the same problem as PDSaga did during flights, the value gets contantly updated during run time and we can't permanently patch de fov.

SEGA SEGASATURN SEGA ENTERPRISESGS-9126 V1.00119961209CD-1/1 J FIGHTERS MEGAMIX

Code:

80055B55 C000

Initial value 256 Float big endian.

 

I'm not sure, but it seems this code works in all modes. Need more tests:
----------------------------------------------------
Widescreen for FIGHTERS MEGAMIX [Japan] (hex code):

Code:

File: "1ST_READ.DAT"
(Offset / Value)
51B0C / D141
51B0E / D142
51B12 / 1040
51C14 / 0001
51C1A / C000

 

Small update for Elan Doree. This code activate the hidden english mode (title screen, epilogue).:
Action Replay code:

Code:

06045E76    E101

Hex code:

Code:

File: "0.bin"
Offset / Value
41E76 / E101

 

@Espirral and @paul_met (nice find on the English mode for Elan Doree).

In Megamix the ropes are shearing quite a bit after the hex edit in your gif, and in Elan Doree you can see everything get progressively worse with each ratio, especially the stained glass.

Are these separate codes and hex for the 3d fighters and the 2d backgrounds? They are handled by different processor so they made need separate fixes.

I think for elan doree, if the camera for 16:9 was pulled back a bit to make it feel a bit closer to the the roominess of the 21:9 sample I think that would be the ideal for this game given the low resolution.

 

The same value is used for backgrounds and 3D models. Otherwise, backgrounds will be simply stretch. The distortions on the screenshots may occur because they were made at a different time, when the camera could slightly change its position. Also, the decrease in the quality of the backgrounds depends on the hardware scaling of the image by the console itself (Saturn does not scale the image very well).

 

Yes, the Saturn just isn't going to be as impressive as the other consoles with widescreen codes.

I read that some games render the backgrounds at high resolution and the 3d characters low. If high res mode could be forced on backgrounds it would make the textures more dense to start with. This might work well for backgrounds that are large enough to still extend beyond the edges of the frame buffer.

It might also ruin some things though. Not expecting you guys to go that far, just hypothesizing.

Thanks for all you do for the scene

 

Aloha

Thanks for your work on this you guys.

I applied the hex changes to Panzer Dragoon Saga (USA) on a CCD version of the image. was able to find the appropriate address and the change appeared to go fine.

Burnt a copy of the disc and popped it into the saturn and could not see any difference at all between my original and the modified version.
Did i miss something?

 

How exactly did you apply the hex code? Did you edit the whole image or only the required file? If the first option, then perhaps the program with which you recorded the image to CD, automatically corrected your changes, because the data in the sectors did not match the information in the EDC / ECC blocks. To check this, re-create the image from your recorded CD and check if the changes you made earlier are preserved.
