Dumping questions

[van_halen]

I bought a Game Doctor SF7 a while ago to be able to back up some prototype stuff. However, a few of them refuse to dump correctly, Pilotwings among others. The emulator says the checksum is bad, but it loads up and plays fine until the start of any simulation part. From there everything gets black and only the music and sounds are playing. I'm fairly sure the DSP is not the final version, which might explain it all. If so, will that automatically render the checksum bad even if it actually is a good dump?

Also, if I were to dump the contents of the DSP, is it possible to somehow do it without having to desolder it from the board?

It is entirely possible that the Game Doctor SF7 might not be able to handle the mapping of the prototype carts, especially a DSPx game. Personally, I would suggest getting a Retrode, it should be able to dump any non-SA-1 game. I might not be the best person to ask about such things. I suggest asking on the SNESfreaks forum. They have several SNES hardware experts who would be able to help you out (don't worry about the fact it is a German forum, they will be able to help you in English).

You should listen to this guy.

You should also mention what emulator you're using. Have you tried BSNES?

[badinsults]

If the DSP1 chip is not the same as final, you might have to dump the contents of the chip for it to emulate properly. BSNES does have the facilities in place to emulate it if the prototype DSP1 image is dumped.

I should add that if http://byuu.org/articles/decap is any indication, dumping the DSP image is non-trivial.
