Patching GDI images

For IP.BIN storage problem.I think if the buildgdi can read boot sector from an gdi dump and apply all its patch works on the fly in memory.Then the life would be easier.

=]

 

Did someone ever figure out why Dino Crisis doesn't play its FMVs when displayed through VGA??
Are there other games that have such side effects on the DC?

 

If you PM me a download link for the GDI version of that game (European one) I can have a look at it. Does the back cover of the game mentioned that it is compatible with VGA? I noticed that some games reinit the graphic stack everytime they play videos...

 

No it has to be patched in order to output something over VGA. But the FMVs simply don't play (or show up) once they start.

 

I'm gonna look that over probably this week. I'll let you know what I find.

 

Do you know what I have to modified in the ip.bin in order to use the 1st_read.bin patched for vga mode ?
I replace the 1st_read.bin but I have always the message taht the is not vga capable...
I tried to change the 0799A00 in 0799A10 in the ip.bin but it doesn't work... Same things if I built a .cdi file...
Could you help me please.

 

61st byte of ip.bin, should be set to ASCII '1', or 0x31 IIRC.

 

Thanks a lot, I 'm trying to patch skies of arcadia with the great 1st_read.bin patch of japanese_cake.
I use hex edit for open my ip.bin, as you said the 61st byte is the A, so I have to replace the A by 1 ?
Here my beginning of ip.bin :

Sorry for my ignorance and thanks again for your help.

 

It's the byte after it I think. I must've started counting at zero, typical programming way to count.

 

i'm find on HDD perfect program

 

Thanks for you two

I have already tried to change 0799A00 in 0799A10 but it doesn't work.
I restart from the beggining to be sure I have left the 1st_read.bin patched and not the original.

Your program is very good and very easy to use ! Some games like Virtua fighter 3tb are vga capable but its ip.bin is in 0799A00...
Maybe I have to change some other things. I hope your HDD program will be helpful.

I'll do another test this evening.

 

You need to replace the 1st_read.bin with the patched one & rebuild the GDI or the CDI (you will need to scramble the 1st_read.bin if it's a CDI you're using, or if a scrambled one is included use that) then add the 1 to the ip.bin

Or just download the NTSC version as that has it native.

 

No need to change the scrambling of the 1st_read.bin for commercial games when making a cdi, that's done in the hacked ip.bin bootstrap.

 

Yes you have right, but I want to spread a pal version with european langage like I did for resident evil code veronica X from the amazing work of "truemaster". And for me I want to played in vga in french with my own dreamcast ;-)
I delete in my data file the 1st_read.bin original by the 1st_read_patched.bin that I rename 1st_read.bin then I build a .cdi file with cdi4dc with the ip.bin with 0799A10 flag. May I should create in first a .gdi before a .cdi.
When I boot in vga mode I have the message : the game does not support vga ; and when I boot in rgb, nulldc crashed... Of course my gdi original version work well will nulldc in rgb mode and I see japanese cake present a screencapture of nulldc in his journal.
In case of use a 1st_read.bin patched I tried to patch the 1st_read.bin original with the ppf file japanese_cake has joined with.
Thanks again for your help.

 

If you're making a cdi, you still need to run binhack on the 1st_read.bin and ip.bin. Check my signature for binhack32.

Try using my Selfboot pack to build the CDI. Read the readme carefully, you need to mount the resulting nrg file in daemon tools and to make a cdi out of it with discjuggler to create a proper cdi before testing in an emulator or burning to disc.

 

When I've done a selfboot file with selfboot.exe, the result selfboot.nrg is not always see by discjuggler... I don't know why but when I put it on daemon tool, discjuggler don't see the time of the image it's written 951321hours and when I create the .cdi discjuggler create a very very huge image (a lot of Go !) and of course it doesn't work. There is only a few of selfboot.nrg which give me a .cdi correct...
I rename binhack32.exe to binhack.exe in order to use it with selfboot.exe.
Thank you for your advice I look at your tools.

 

Your tools are very good. Thanks for them
Do you konw which kind of files i can put in the data 1 in order to win 65Mo of place in the disc. I had do some test but I never used success for use it.

 

Any files work, as long as they don't need to be read fast (avoid videos and executables). My pack is now 32bits, so no need to change binhack32.

The standard procedure is to use the selfboot.bat, then mount selfboot.nrg in daemon tools and image the virtual drive with discjuggler.

If that doesn't work, I'll need the console output of selfboot.bat at the very least in order to help you.

 

Ok I try like you give it.
Here a picture of my discjuggler bug the selfboot.nrg do 1Go

 

That's weird, try installing an older daemon tools version?

Can I see the text in the console when you run selfboot.bat?
