Source Code to SS ISO Country Converter
- Thread starter Weston
- Start date
I am under the impression that tyranid does not read this forum... But anyway, if you try and convert an ISO and then run "fc -b oldiso.iso newiso.iso" in DOS, you'll find that the "conversion" only changes 1 byte of the file. It's normally 64 bytes into the start of the .ISO and its a letter (for example J changes to E ou U for european or american Saturn models)
The correct way to do it is to find the header, that begins with the "SEGASATURN" string. But I really don't have the documentation around here. Can anyone help?

It's not just that one byte; that's only one part of the change. The other part is changing the region signature, which is at offset 0xE00 of the disc image if I'm not mistaken. This area is a text string describing the region, examples (from memory, so these might not be 100% correct) include:
For JAPAN.
For UNITED STATES and CANADA.
For TAIWAN and PHILIPPINES.
For ASIA PAL area.

Hn, weird. I could swear the second check is optional, since i used my converter allways ever since I built it and never got a bad burn... even with the description code wrong. Funny, eh?
Yup your right i dont read this forum, and yeah its mainly a one byte change however it is a good idea to change the id string as well as you never know. I dont use it any more since i got a par anyway.
If you actually want the source code i dont mind releasing it. Should compile easily under almost any o/s you care to mention.

Well, thanks for your response ^^. I'd love to see the source code, for example, to see if my converter ended up to be more advanced than yours 
Err point to note on that rls
Under dos i used conio for input, and under linux i just used the std fgets functions. however as the linux verison was only 1.1 and not 1.2 i modified the dos version to accomodate. however i forgot to remove the #include <conio.h> so you may want to kill that line before compiling

i got the code to compile under mac eariler, if you're interested.
it's a quick and dirty port, but it works.
thats mac os 9, btw - mac ppl can get it (if they dont want to compile themselves or login to my ftp) here

You can try and port my code. But it's QuickBASIC. You'd have tons of fun making it into C, belive me.
i'd hope it would . . . it's a simple sioux prog.
aqua? you'd have to wait till i finish the book on the mac toolbox and it's own extentions and such.
