64DD Emulation

[faceless79]

Ok not to sound like a noob or anything but i was just wondering if anyone has even ATTEMPTED to emulate the 64DD. I know it would be somewhat difficult due to the relative obscurity and rarety of the system but seeing as how 1964 0.99 does run the bios it tells me that 64DD emulation is atleast possible. So has anyone ever heard of anyone EVER working on and emulator that is capable of running 64DD games?

There are not 64DD emulators at the moment.

Maybe this link can help you.

1964 can run the IPL ROM?

I thought only Ultra/SupraHLE could, even with the proper hex edits.

I know there arent any. I wanted to know if anyone has even tried. And yes 1964 does run the IPL ROM except it does have quite a few errors.

Daedalus runs the IPL4, too.

I was a beta-tester for these guys making a 64DD emulator. It's on hiatus now, and it has been for a year. The latest version could only run the unmodified BIOS and the F-Zero expansion. It crashed when trying to load or make a level, though.

Didn't realize it got that far even. Then again, a good part of that is just setting the right stuff to the right address spaces. The software end of things is relatively well documented at least.

Well, at the very least that would imply it wasn't a disk-access error. Stupid question, but did the stage crash after the stage select screen (the line-drawing of the stage), when you went to play it? Both the editor and DD/EE tracks utilize sound files that aren't present on the cart. Then again, it also would do a quick write or two to sram in both cases, wouldn't it? Could be redirecting the write to the 64DD space, which would fail due to write-protect. In either case, the stage would have already loaded in order to make the squigle you see on the track select screen.

Just speculation. It's always interested me, ever since losing an auction on ebay a few years back ;*)

Has anyone used the same method to rip out the sim city expansion? Most rumours of dumps are bumpkis, which is why I ask. That is particularly interesting since could would reveal the structure wrapping image data from the artist series.

-oh, if you have a chance, could you dump out the RDRAM of it on the track select window? It would aid in activating the track select menus so GS-uploaded stages don't need to replace anything any longer.
