Hi Folks - NAMCO C532 Question !
Hi So here I am trying to extract samples from my NAMCO System 12 ROM's - specifically the 'Wave' labelled ROM file but it seems when using Audacity and importing the RAW DATA it always ends up heavily distorted ?
I have successfully ripped from other MAME ROMS with no issues, and Its definitely the correct file as you can hear the actual samples however as I stated they clip like crazy and it seems it's 'within' the actual file.
I was hoping someone could chime in and offer a complete noob some help, I've tried almost every import setting i can think of but no luck yet
Basically I'm trying to extract the orchestral sample library that's used in the Game.
Thanks in advance !

Thanks so much that makes sense - Now if i could only get that DOS app to run on WIN 8.1 ! arggh
The program is not a DOS program. Use Command Prompt to run the program.

I might get back to VGM ripping someday.

easy way: make sure the program and your sample roms (you can also use an uncompressed VGM file) is in the same directory, then shift-right click the explorer window and select "Open command window here". In there you run the program by entering the command:
Code: Select all
mulaw <name of sample rom> <name of output file>

Hi ctr , listen thnaks for your help ...ctr wrote:easy way: make sure the program and your sample roms (you can also use an uncompressed VGM file) is in the same directory, then shift-right click the explorer window and select "Open command window here".

mulaw <name of sample rom> <name of output file>
However bearing in mind I'm an obvious newbie (Beyond newbie in fact!) I assume it should look exactly like this...
mulaw <soc1wav0.2> <soc1wacpcm>
Names are not important for the files just now but I am including the < > ?
because it stated 'could not open soc1wav0.2' which is the rom file that has the samples

Hi , again much respect & thanks to ctr and Valley bell for their help on this.
A wee query now about CPS2 roms, I sometimes notice when I am writing a track using , for example Street-fighter Alpha 3 Samples (Drums/Guitar /Bass etc) They lack some top end from 10Khz and above , whereas when i listen to the VGM in Winamp using in_vgm the overall sound is much brighter (In a good way) and all that nice top end (treble/presence) is back.
Is there any reason for this or am I doing something terribly wrong ? or perhaps it's the nature of simply extracting samples directly from the ROMS?
