Sonic R PC

Does it have an error message, or does it minimize it on beginning, or does it simply not run?
I can probably help you if it's 1 or 2

 

I have the same problem too. Sonic R installs fine for me, but when I try to run it I get the exact same "004801d9" error, and the game never works. The wierd thing is that Sonic R worked fine on my old computer with Windows 98, but now since I have XP it won't work for me at all.

Here is one way to get the game to work (sort of): All you do is highlight the Sonic R icon in your directory that opens the game, and hold down Enter. After a while the game will be forced to start up, but when I do it there is no music, even though my sound card supports music from Direct X.

A little off topic: Sonic CD also does not work on Windows XP, but at Sonic CuLt they have a download which fixes the problem, but when I tried to do it the game started up, but it still had no music, even though I have an excellent sound card.

 

Knux Fan:

Sonic R has no music for most the released discs, it's not a unique problem.

And, you have to configure your INI manually for it to have music :P

 

Wait- I do have a disk with music. Does that mean I have a rare copy of the game? =P

 

You lot all need Saturns, the Saturn version of Sonic R owns the PC version.

 

I bet it's a config problem -- but that's just a guess. Open the INF file in a hex editor and use these notes to modify it:

I should also note that Sonic R does have a bug -- it tries 15-bit color EVEN THOUGH it is set to 16-bit.... and if your graphics card/chip doesn't support 15-bit correctly, it will use the default color and res mode (640x480x16-bit). In other words, if you like 16-bit, but use a lower resolution, and your gfx chip doesn't like 15-bit color, it will change back to 16-bit 640x480 because it's stupid like that. Just thought this was an interesting bug that I would point out to interest people.

Also, yes you can have greater than 640x480, but the problem with those higher resolutions is that it doesn't draw the sky correctly since it wasn't designed for those higher resolutions. Still, if anyone wants to try it, be my guest.

 

Some copies of Sonic R don't even have a trace of music on the disc, not even in a CD player and has only a data track (1), and I don't think they're configured to play music....

 

What about fixing that annoying "004801d9" error that makes the game not run? I've tried the Windows XP compatibility FAQ and that doesn't work. Is it possible to fix this error and make the game start up?

 

Get a Saturn. That always works and always has music. They're not expensive.

 

16 bit program loader? I doubt that Sonic R is 16 bit, it looks definitely like 32 bit.

Anyway, I can explain the error, but not why it happens.
Your log has a "State Dump" which shows some assembler instructions and the contents of the CPU registers. The error is an "Integer Overflow", caused by "idiv ecx".
IDIV means integer division, that is division of a *signed* integer (the unsigned equivalent is DIV). The signed 64 bit number represented by edx:eax (here 0x69E4F580) is divided by ecx (here 9). The result is stored in eax (and the remainder of the division in edx). However, eax is only 32 bits, and since we are dealing with a signed operation, only 31 bits can be used to store the number, because the uppermost bit is used to indicate the sign (positive or negative).

Now, the problem is that "0x69E4F580 idiv 9" equals "0xBC41B47". This result is positive and requires 32 bit, and hence can't be stored as signed number in eax (only 31 bit available for a signed positive number). The CPU detects that and raises an Integer Overflow exception.


That said, my version of Sonic R, published by xplosiv, runs just fine in Windows XP, with CDDA music and both in Direct3D and DirectDraw mode. I just installed and tried it again, I didn't even have to configure anything. By the way, if you don't get any music in a PC game that uses CD audio, try to enable digital playback for the drive in the control panel.


Edit:
I just looked around at xplosiv.net some more and found that they have a Sonic R FAQ which mentions that error at address 004801d9 - Link.

 

Luigi_Link, there aren't even the audio files located on a disc for some of us. I got one from a Sega pack, and it has zero music. ;P

I know that the no-music copies are lighter in color then ones with music on them, too. And, I think the title screen was a little less fancy.

 

My Sonic R works fine in XP with the exception of Netplay. Attempting to open the SrNet will result in an immediate crash, the kind where you cannot use ctrl+alt+del, alt+tab, etc. It's not even nice enough to atleast show me the blue screen of death to let me know everything's "fine". I only have about 32 mb of onboard video memory, nothing extra installed such as a card or anything. Sometimes having the latest 3D graphics card can make things worse.

 

Windows XP is based primarily on NT technology, so it doesn't have the BSOD.

And uh... I only have a graphics chip, not even a card, and I can view 3D graphics fairly okay (albeit with lag and skipping and such for N64 emulation).

 

I have a saturn, but I have seriously looked everywhere for the game. May I please have a clue as to where to get it (Or a way to burn it myself)

 

Get disk image (with music). Burn to disk. Insert into modded Saturn and enjoy.

I can't help with the modding though, sorry.

 

Actually they work fine for the OS for viewing/reading them.Other programs sometimes have a hard time detecting CD-RW drives.For example Gens won't detect my DVD-RW combo drive OR my CD-RW drive, so I installed a plain old CD-ROM drive and it works fine with it.But don't be an idiot like me and stuff 3 different ones in your machine!

 

Actually it does. The only time I got a BSOD in XP was when I used Game Shock (one of those cheat finding programs) to plug values into my online time in aim, which immediately brought upon the end of my Windows session :P. I'm sure it's reproducable if you have nothing better to do.
