Snatcher Audio/Freeze #293

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Hello, I am running Genesis Plus GX 1.7.1 on the Wii. Regardless of rom (I have 
used multiple bin/cue and iso's) I cannot get the cd audio to play in Snatcher. 
Initially I thought this would be fine, however, the game always freezes after 
leaving for the factory at the start of the game. Everything appears to 
continue to run normally it just loops on the sound and image of Gillian in the 
car. 
Scouring the internet this problem seems to be common and related to the 
lengths of the audio. Yet the .cue and track lengths appear to be in order. I 
have placed the bin/cue in the rom folder. What am I doing wrong?

Sorry for any noobishness of the question.

As you figured out it is indeed a problem with your files: the number or length 
of detected audio tracks are not correct because you are either using a bad 
rip, unsupported file types or an invalid cue file.

It's impossible for me to know what's wrong with your files with so few details 
(which "multiple" bin/cue and iso's ? what do you mean by "appear to be in 
order" ? compared to what ?) so I suggest you at least upload the cue files you 
have been using and give a little more indications about the various files 
(names ? types ? number ?) you were using.

Also gives the number of track and total length returned by the CD player when 
you enter the Sega CD boot menu (press any key when Sega CD logo appears). Can 
you play
all audio tracks from there ? If you don't, you can be sure your image is wrong 
and the game will hang at various spots because of that, a valid CD image is 
required for that game.

On a side note, you should normally be able to go past that spot by loading iso 
or bin image without any .cue or .wav file (the emulator automatically setup 
the correct TOC for that game if no audio tracks have been detected) but you 
won't get any audio CD playback

Sorry for the lack of specificity, I'm just figuring this stuff out. 
I just tried the rom using Kega Fusion on my laptop and it runs perfectly, and 
allows me to play the tracks in the CD player. When booted in Genesis Plus on 
the wii, the CD player shows 55 tracks, which when played have no sound. 
Attached is a screenshot of the .cue. As for loading without the .cue, I tried 
that but it still freezes in the same place.
I appreciate your time, and the effort put into the emulator.

Yes, this cue file is misinterpreted by genplus-gx because it is missing INDEX 
00 commands (which should indicate some pauses between tracks). What is the 
size of your bin file and its exact filename ? Keep in mind the first line in a 
cue file is the name of the bin file, make sure it exactly matches your bin 
file when loading a cue file, that is, in your case, you should have a file 
named SNATCHER.bin (caps included) in the same directory.

Also, again, what is the total length reported by the CD player ? it's 
displayed right with the number of tracks, you cannot miss it. 55 tracks when 
your cue file says it only has 21 is definitively not good, no need to try if 
it still hangs until you got the correct number of tracks and correct disc 
length.

Here is an example of a good cue file, BIN file should be exactly 625192176 
bytes

Last thing, go to INFO screen in main menu after you loaded the game and report 
the ID number (something like T-XXXX or GM-XXXX) you see below the game name

Ok. It's SNATCHER.bin at 625,192,176 bytes. The updated .cue is attatched.
The total length reported by the CD player is just 7:06,  still at 55 tracks. 
The ID number on the info screen is T-95035 -00. It then says Checksum: 2020 
(0000) (BAD). The region code says J (USA).

When loaded with Kega Fusion the same bin/cue gives me 21 tracks at 59:06. 
 I previously tried the 'redump' titled bin that you posted the .cue for and experienced the same issues.

Thanks for the help. Really appreciated.

what updated cue ? updated with what and from what ?

anyway, i renamed my bin file to SNATCHER.bin (the size of your match and used 
your attached cue and the CD player reports 21 tracks and 59:06, just as 
expected, so I don't know what to tell you.

the number of tracks and total length you got does not make any sense, really, 
there is no way the code could end up with something like this unless the .cue 
file specified it

out of curiosity, what CD BIOS version are you using ?

It seems there was an issue with my SD card. I wiped and reformatted it, and 
now the it works fine. 
Thanks for helping me identify what the problem was, I probably never would 
have worked it out otherwise.
