Re: N64 Core Possibility? (Update! Robert Is Working On This Core!)

with talks on the forum about a mish mash of software and hardware emulation, you never know. Such an approach would have all the same issues as the current software emulators. The N64 hardware is fast and that RDRAM has extremely low latency and the CPU and graphics could use it simultaneously. That's not going to work well with a hybrid approach...

I think that's out-of-date, it needs to be zero now.

I just used the standard ini file and it worked out-of-the box for me.
Are you using the analog board or direct video?

Re: S-Video and Composite Over Component Output! (Custom Cores)

Without the capacitor the signal is going to be out of spec. Even though most TVs will still display a picture, it's going to have more artifacting than it should. The capacitor isn't really that robust of a solution, an actual luma trap will work better, especially on some arcade cores and Genesis.

Re: Simulating CRT scanlines for Guncon?

Sample and hold displays cannot emulate this behavior. They are not fast enough, by an order of magnitude. Plus there's an issue with display latency on top of that.

The Tandy didn't have any speech. I think the ao486 core is probably too full to add this sort of stuff. I think it makes sense to put the Tandy 1000/PC jr and PC/XT in their own core as they share a lot of components and things like cycle accuracy could be possible. We're never going to have that in the ao486 core, at least not on the DE-10 Nano. ...

Re: Release DE10 Nano Overclock Kernel BETA

The big problem with the N64 is it has pretty large and very fast memory busses, much larger and faster than pretty much any other contemporary device. The SDRAM boards are not particularly large and fast by comparison, and it's taking a lot of clever designing like running the SDRAM faster than the original system's memory so that it can emulate ...

To use component with the analog board you need a cable like this one:

You would also need to turn on the sync on green switch and update a few settings in the mister.ini file.
