Hi: is it working on Dreamshell ?

Hi: is it working on Dreamshell ?

Probably not as the first 256 bytes have unprintable characters. I don't really know what that means though.

Probably not as the first 256 bytes have unprintable characters.

this problem only applies to GDEMU_SD

Take my gdi version with dreamshell.
Optimise and run it with same config as dragoncity list but loader 8 (0.7.x).

GDEMU_SD crash if first 256 bytes of IP.BIN have not printable symbols
all not printable symbols need replace to space (0x20 in hex)

Is someone able to do this and re-upload? I don't know what counts as a "not printable symbol", and opening the file in Notepad just brings up a load of gibberish. I would assume the problem is the up arrows and yen symbols, but there are so many other odd symbols in there that I wouldn't know where to begin.

The first 256 characters inside IP.BIN are as follows;

SEGA SEGAKATANA SEGA ENTERPRISES598F GD-ROM1/1 E 0799A10 T8118D 50V1.00120001003 1ST_READ.BIN SEGA LC-T-81 F355 CHALLENGE

Which symbol is GDEMU_SD not able to understand?

By non-printable characters he is referring to the IP.BIN file in a hex editor. I have no idea how he knows that the first 256 bytes of the IP.BIN file has non-printable symbols unless he checked or guessed. If he checked idk why he didn't edit the IP.BIN file in a hex editor after going through the process of checking in one, and if he guessed idk how he thought of something that specific unless this was a common problem. The GDemu is much more common and used compared to Dreamshell, so it is a possibility.

I've run into two majors issues trying to do this myself, the Wizard for IP.BIN builder has vanished off the face off the face of the internet. So I couldn't just make a new IP.BIN file. Editing the current IP.BIN file in a hex editor is what I'm trying to do now, not looking good, pretty inexperienced with hex editors.

two errors, the first in the IP.BIN 4 Win program, which adds garbage to IP.BIN, the second problem in the GDEMU_SD program, it does not check the contents of IP.BIN

here is the simplest example that will solve this problem

Code: Select all

#include <ctype.h>
#include <stdio.h>

int main(int argc, char **argv)
{
	FILE *fp;
	unsigned char buf[256];
	int i, fix = 0;
	
	if (!(fp = fopen("IP.BIN", "r+b")))
	{
		return -1;
	}
	
	fread((void *) buf, 1, 256, fp);
	
	for (i = 0; i < 256; i++)
	{
		if(!isprint((int) buf[i]))
		{
			fix = 1;
			buf[i] = 0x20;
		}
	}
	
	if (fix)
	{
		fseek(fp, 0, SEEK_SET);
		fwrite((void *) buf, 1, 256, fp);
	}
	
	fclose(fp);
	
	return 0;
}

sorry I reread my original reply to the other poster and it sounded WAY more snippy than I intended. Will see if I can do this but probably wont be apt at this.

Awesome

[Ro Magnus Larsson]

1st Presets for Dreamshell ?
2nd It works with IP.BIN or without it ? the three tracks are BIN files...
3rd you did it only for Dreamcast PAL version ?

Use 0.7.x B1 loader, optimise the gdi.
