For 300-1200 bps you have to save the recording as 22050 Hz, 8-bit. Make sure it's never 16-bit. Only for 2400 bps is the recording supposed to be saved as 44100 Hz.

You won't get the full dump when dumping it as NROM. That would be just used to dump the menu part, which you/somebody would then need to reverse engineer to find out how the menu selects different games, and then write add support to TapeDump based on that.jpx72 wrote:PS When dumping the cartridge mentioned above, I'm getting sound from Famicom for some 6:35 minutes, then sound stops. That can't be the whole cart, it has all the Rockman games on it.
You are getting different results semi-randomly because the lower bank registers of the mapper start at random values. For figuring out the mapper this doesn't matter, only the last 8K of the ROM matters in this case, so both ROMs are fine. As for why the graphics are garbled, the CHR banking regs are random at startup as well. This also doesn't matter for this task.jpx72 wrote:EDIT: I have flipped the mirroring switch on my tapedump cartridge and recorded the thing again, now I got a smaller file...??? Here's the decoded FILE.
EDIT2: although on second try, I got the same file as I got before switching the mirroring. This second file must be some mistake.

Yes, thank you I am now aware of that and I'm thankful that you released those. Nevertheless I must try to find someone who will help me edit them, because I simply don't understand that. All I want is to dump this pirate for anyone who's interested.ccovell wrote:TapeDump comes with its own source, and the mapper files come with their own assembler, so there's nothing stopping you from assembling your own version of the ROM; Powerpak or no Powerpak.
