Re: Genesis / Megadrive core ported to MiST

Weird, Sonic is scrolling in the opposite direction? That's interesting... would make for a nice challenge :)
But it looks fantastic. All the flickering issues are gone!

Re: MiSTer: MiST on Terasic DE10-nano board.

Great work Sorgelig! I have two noobie questions, what is the maximum clock MC68000 based cores (Atari ST, Amiga) can achieve, and second what is largest x86 CPU architecture can be fitted into fpga? Not a direct answer, but to give you an idea the Cyclone V FPGA it uses, at 110K LE, is the largest...

Re: MiSTer: MiST on Terasic DE10-nano board.

Would it be possible to run the firmware with a dummy core for development and debug? That would be super useful to make work on it more robust.

Re: Genesis / Megadrive core ported to MiST

I noticed this on the page:
MiSter allows to use USB storage for cores and their data


This might work with a Retrode, a cart dumper that presents itself as a USB storage to the PC. Then we could play Genesis games from carts! :)

Re: Compatibility/accuracy database for FPGA cores (Not JUST Mist)

The way I describe is that FPGA are a kit to build Systems-on-a-Chip (SoC); miniaturizing the whole hardware in a tiny box. There are two objective advantages: it's cheaper than cloning the original electronics, and it is MUCH more power efficient. As you say accuracy is a problem, but also the fact...

Re: New Core for MiST ? How?

Re: Porting Cores and More

It's not possible to port the cores to the MiST because the HDL code isn't public. The fact that the NT mini has an FPGA just means it has similar hardware as the MiST, but the source code for what runs on it has not been made available (and is unlikely to be unless Kevtris changes his mind). The lo...

Re: ZX-UNO Spectrum FPGA

One challenge is to accurately measure % of support. One can run games and list them but its super time consuming. A test suite would be nice but then several cores pass the existing ones... its the undocumented opcodes/features that are hard.

Re: ZX-UNO Spectrum FPGA

I'm not the most heavy duty user of the ZX Spectrum, but if you don't care about hardware extensions, the MiST core is as good as it gets. I cannot tell the difference from my real ZX and 2+ computers combined with a "DivMMC Enjoy!" extension for an SD card. In fact I use the same SD card ...

Re: ZX-UNO Spectrum FPGA

Apparantly the ZX Uno is the predecessor to the ZX Spectrum Next kickstarter. It seems the same developers are behind both. Where do you see that? The developers are definitely not the same; perhaps you are thinking of the TBBlue board. That said, the ZXUno is open hardware, so they could have take...

Exactly. Conpatibility lists are still useful to check if somebody else ran a particular game, but it can stay as is for a long time.

Re: M

I suppose then that emulators do implement all these hearders then, right? Implementing too many headers on an FPGA may not be possible because of timing constraints. Each new header makes the memory selection lines more complex and we will eventually hit a hard limit. Whether the limit is far enou...

Re: Perfecting existing cores

The thing of the NES is that games correspond to specific mappers so you can check how many extra games would be supported by implementing a mapper. On a computer core this would be more difficult. That said at least the Gameboy and PC Engine core have missing mappers too, each covering a few games.

Re: Perfecting existing cores

Sounds good. I also have a Zx-Uno but I must admit I've been using it less than the MiST. As far as I can tell both cores are written differently (due to Altera vs. Xilinx IP/macros) but perhaps a common standard can be made.

(splitting from the Jupiter ACE thread) Certainly, taking into account coders' motivation is important but I think the motivation is not only fun, there is also a social aspect.

Re: Jupiter Ace arrives at MiST

I don't think it's that simple; it probably needs somebody to check the timings on the original hardware. That said, if developrs can outline some busywork to "farm out" I'm sure there will be some volunteers.
