Oooh, and btw Beyond Oasis doesn't work. And obviously neither does Shining force 1and2. Annnnd, i odnt think this is what you're looking for so far as SVP documentation: and i only glanced at it (because like i said, i dont know what your looking for-plus you've prolly already seen it)-but check this out: SVP info?

​

No if you read the document it says:

" To emulate the SVP chip, somebody needs to figure out how to dump the
internal ROM (the test menu shows that it has a DSP ROM reading option,
perhaps sending a certain command to the SVP makes it map it's internal
ROM within the $300000-$3FFFFF area) and figure out how the DSP works."

I don't think this has been done yet, so svp emulation is not possible yet.

it's pretty much undumpable. the only way to emulate it is by HLE. which won't work on the gp32.

GP32 Green EU version - also White Screen
My Unit doesnt do 160Mhz...only 133 to 144Mhz

gp32 blu (gbax 166verified) doesn't work white screen and hangs

any progress on the emu?

yep, you won't find news in this thread though. Try the thread in the news section.

Since the emu is running at pretty much the limit of the system, adding the SVP chip is a but much to ask don't you think? It would run very slow.

Do you even know what the SVP chip does? No, so you can't say how much it'd slow it down.

That means that nobody (yet) knows how to do it, not that it is complicated, or that it is slow.

Or even worth it.

[onionfrog]

What game(s) even use that chip?

 

[dowboy]

Just Virtua Racing I think..

Yeah, I didn't care, just was making sure people get their facts straight.

I think it would slow down the emulation to a crawl though.

While it is not known outside of Sega what the SVP actually did, it was doing a lot of work that the Megadrive itself simply could not do. There were a lot of polys being thrown around that game, so the MD needed the extra chip which did most of the work.

That being said, as has been said here already, DrMD is pretty much pushing the GP asd it is (good emu on most games at 144mHz), with the addition of SVP I don't think it would run at any playable speed even at 166.

Would still be nice to do (if it was possible that is, which it's looking pretty unlikely) just as an experiment to see how fast/slow it would run. After all, PSX has been tested....

@onionfrog: only VR used the chip. Sega were going to use it in other gaems but the price needed to produce the game with the chip put an end to any future releases.

Yes I know what it did, it was a co processor used to render 3D polygon graphics on the MD. Adding that would definetly slow down the emu, ALOT.
