SVP => Samsung SSP1601!

[Tom Maneiro]

Recently some Sega docs were unearthed and revealed that the SVP chip on Virtua Racing was not a SH-1, but a Samsung SSP1601. However, there are almost NO docs about this DSP (no devkits, no emulators, just a simple datasheet).

If anyone can find info for it, please post it!

well, according to various internet sources, it's a modified Hitachi SH1.

Nope... Someone discovered recently that there are no Hitachi parts on VR, but the SVP is a Samsung DSP. Some places confirm this, but since there are no docs about programming the SSP1601, cart can't be emulated yet.

(if it were a SH1, the things would be different)

Well, it's most likely that the SSP1601 was a custom designed chip that samsung was chosen to make. If so, then samsung won't have any support for it.

Most likely the only way would be to fet a group of people like oompa loompa together to reverse-engineer it based on what signals the chip itself it sending out when in-use.

But since it's only used in one game, and it's just a port of a better game to a older and slower console, i doubt anyone will ever do it.

After all, the SVP IS a SSP1601, and it's now emulated
