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

For example, Blazing Lazers gets unplayable and corrupted once you finish the first half of first stage and Street Fighter II' Champion Edition has similar issues. SFII actually is the biggest ROM on PCE HuCards and has a one-off a custom mapper. Would be nice to fix it (given the game) but it also...

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.

Perfecting existing cores

(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. When we, coders, see people enjoying our work and giving us appreciation back, it feels great. So recognition is a factor ...

The MiST SCART cable should do the trick? It's not too expensive. Or you don't have SCART perhaps?

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.

Re: Jupiter Ace arrives at MiST

Well some of us could contact him and safeguard the source just in case. Also the arcade cores can probably use some rework to exrernalize the ROMs to avoid any copyright issues.

I think the problem is the MiST SDRAM is not fast enough to multiplex ROM data.

The joystick test is part of the firmware. Should be accessible from most of the cores that use the standard menu (some cores have their own OSD).

One strange thing I noticed is that the music in Dragon's Fury is slowed down... even though the whole game seems to be at full speed. Not a big deal, but thought I'd mentioned in case you're looking for bug reports / noticeable differences with the original.

He could still publish his code minus the copyrighted part.

I guess this shows the need to have a core load data externally to avoid such problems. But obviously that's harder to write since you need to grab the files from the SD card and store them in memory.

Re: How to map keyboard keys to joypad buttons?

Just to clarify, are you trying to make your gamepad act as keyboard right? Not the opposite (use keyboard without gamepad). The relevant code is in /usb/joy_mapping.c in the firmware. There is a function to map via .ini but its not documented. I don't remember if it's because it doesn't work well o...
