DSP-1 emulation

neviksti, do you think you might be able to find out anything about the SVP chip? If you can, there's a forum topic here about it.

(Some new information about the chip may have surfaced in the last couple days, as were not sure if it's really a Samsung SSP1601).

Possible Datasheet

Documents on the "possible" chip

Forgive the ignorant question but what do you mean by "dump the chip"? I always thought "dumping" was the process of extracting binary data from rom catridge/PCB/floppy/HD etc.

The SVP chip is basically "virtual reality". There's information on the chip that needs gathered before it can even be emulated. (It adds stuff like polygons to the Virtua Racing game).

I know about the SVP chip (played the Genesis VirtuaRacing back then) and I know it's not emulated.

I was just wondering how you dump a chip, as I've read things like "dumping a cpu" and wondered wahat is meant by that.

Basically, somebody has to cut the top of the chip off, and try to read the bytes using a microscope.

What determines whether this is possible with a chip or not?

Well, I think it can be done with almost any chip. Although a person might have to go through at least 10 chips to get any useful information.

Ah, I guess that explains why it hasn't been done for many emulators. No small task.

You'd get more results faster if you RE'd the chip. The hardware required to RE is also less expensive.
