New Project - DCNincest64

[wraggster]

Just so as you know, the Nintendo 64 has an impressive Homebrew scene with many fine games, demos etc. http://www.pdroms.de is a good place to start.

Got a few questions

will you use HLE to get better speeds etc

also could a cable be made for connecting an hard drive to the Dreamcast for using as virtual memory storage space etc ?

/me awaits a flood n00blets demanding a release NOW to play perfect dark on their DC's, though fortunatly the other un is likely to get them more than us. Next inpossible feat = getting a supermodel to fall for me, get on it!

Sorry about butting in here, but this is a question I can field. Yeah, it could probably be done, with a lot of work. However, I don't believe the expansion bus is quite fast enough to make it practical for vmem, and it probably could only be done for IDE drives, not SCSI. Now, where as it would be nice to have 40+ gig of drive space on a dreamcast, it'd be great for linux, if not for vmem I don't really see what it would allow the DC to do that it can't do already with other hardware.

it's 25Mhz x16bit.. the protocol/framing isn't nowhere as as complex to deal with as PCI.. so a theoretical 40MB/sec practical 5-6MB when you need a driver to access a device....
which is more than enough for anything.. I don't see why you can't hook up a SCSI controller.. a 53c90 could easily be attached.. even memory could be mapped in there's several megs of address space there..
a couple of TTL's (or 1-2PLD's), and a disk on chip and you got 10-20mb of
space to play with.. question is who would be capable/willing to build it..

yeah it would have to be made and tested etc but think of the great ness a dreamcast hard drive would bring to the scene.

Not forgetting it might help both a GBA and n64 emu for DC too.

Nincest64 isnt an emu im familiar with, what does it run etc and whats the homepage?

[Hawq]

I aint surprised your unfamiliar with it, it was discontinued in 99 at a stage where it only ran a few demo's

[GPF]

it was an emulator that was discontinued, so there is no longer a homepage for it. The emulator only run the fire demo and stars demo, haven't been able to get anything else to run on it, it either crashes or just shows a black screen.

I have hacked the emulator code and added some nulled out function calls and have gotten the N64 logo from WaveRunner displaying.

I cut the WaveRunner64 rom down to the first 2 megs and can get the N64 logo to display on the dreamcast. Its the wrong color but its displaying

ahh there you go then

as a proof of works project, its pretty impressive

are there any source available N64 emulators that are portable other than this one, 1964 comes to mind?

[wraggster]

GPF also posted this :

Only the logo for Waverunner 64 will display on the pc, other than that the stars demo and fire demo are the only thing I have found that will run. I cut the Waverunner rom down to 2 megs and can get the N64 logo to display on the dreamcast.

Mario64 just shows a black screen on the pc, haven't tried to see if them emulator crashes if I load it on the dreamcast because of out of memory. My cdr burner just broke, so I have to load every thing up in a romdisk to test it and send it over my serial cable.

I am still researching the feasability of improving this emulator, vs looking at other n64 open source emulators, I have Mupen64 hacked down to the commandline and running a SDL gfx software plugin, but running the demo roms it is using around 16.5 megs on the PC, I have been talking to the Mupen author for suggestions on reducing the memory footprint, but I am still working on that also.

So there ya go
