Re: DB9 Vs USB game control tests

We have recently made a significant expansion of the number of cores adapted to DB9 which we keep continually updated. They are not all absolutely but almost.

I leave here the link for those who want to enjoy it:

Re: ZX Spectrum Core

I see no reason to change memory module, everything worked fine.

I don't know the changes that were introduced after version 20190711 but
the core is broke for me, therefore, I will keep this versión until some better ZX Spectrum port comes out.

Thank you very much.

Re: ZX Spectrum Core

I have no idea what can be done to fix your problem. If i could reproduce it on my MiSTer, then i would look into, but alas it works fine for me. I understand perfectly that it is complicated. More data: - Same module and same fault in another De10-Nano. - After a while in on, sometimes it does not...

Re: ZX Spectrum Core

Try latest metest Yes. It works stable up to 160MHz that starts to fail (is Ok, although with the previous memtest it only failed at 167MHz). This core needs to run 100Mhz, it's tremendous for a core of a 8 bit computer that ran at 3.5Mhz! I honestly think that this core what it really needs is a g...

We have tested that ROM and others with the same result.

Re: ZX Spectrum Core

There is at least another user who has weird behaviour on ZX core with 64MB module (although non-official one). But he has problem with 48K mode while 128K mode works. So i have no idea why. Generally speaking i don't recommend 64MB module - they have high rate of problems. I recommend either 32MB ...

But is an official PCB XS v2.2 and also does not give any problem in any other core.
On the other hand, the new memtest does not throw errors from 150Hhz.

Re: ZX Spectrum Core

I just want to add two things:

All other cores (as well as the other options of this one) work perfectly with my configuration.

The memory module I have is mounted on an XS v2.2 PCB with SDRAM ALLIANCE AS4C32M16SB-7TCN.

Thanks and Merry Christmas.

Re: ZX Spectrum Core

I've tried tap and tzx - didn't find the problem. What steps to reproduce the problem? Yes, it doesn't happen to everyone. I Follow the same steps as always: I select TAP or TZX file and write LOAD "" or I choose LOAD in the menu of 128K ROMs. The same thing happens to me in audio uploads.

Re: ZX Spectrum Core

I plan to release update with fixed slacks. May be it will fix the problem. Ok. The last update fixed this problem, but it's also true that I changed my memory module. Now I have a new memory module with a new SDRAM chip mounted on an official XS v2.2 board that work perfectly in all cores I except...

Re: DB9 Vs USB game control tests

I think it's perfect, everyone will have their preferences and can choose freely :-) The truth is than DB9 with its input lag 0 absolute (like the original systems) is already a fact because there is already hardware and a repository of adapted cores, and of course, all open source and its much chea...

Re: DB9 Vs USB game control tests

Many of us already have old consoles and computers and thanks to projects such as MiST and ZX-UNO we can fully enjoy the experience we felt with our old machines, and so, we can do this and preserving them at the same time. There is no doubt that the technical superiority of MiSTer hardware and deve...

Re: DB9 Vs USB game control tests

You should do the same test with an Arduino Pro Micro and my code here: https://github.com/MickGyver/MiSTer-Arcade-Controller I doubt the performance is greater. I don't have any Arduino Pro Micro but if you give me one I can try it, but I'm afraid too, that the input lag> 0 will be there again. I ...

Re: DB9 Vs USB game control tests

Although it is evident that the performance of the USB control has improved substantially with the improvement of overclocking and with high-quality USB interfaces, only lag 0 is achieved with the direct connection of the control to the FPGA via DB9 connector. You should do the same test with an Ar...

Re: DB9 Vs USB game control tests

Do you consider the XinMo as a high quality interface btw ? This is what I have in my cabinet :) Yes, they tell me that USB interface is the one that has the best performance. If someone knows another controller with more performance, they can say it and it can be proved, but I'm afraid, that the i...

Re: DB9 Vs USB game control tests

Nice I wonder if this adaptor can be modified for SNES/NES etc since you are already using Ardruino :) I think it would be similar to the supergun adaptors that offer SNES/MD/PS controller compatibility. A few of them use Ardruino. These pins really belong to FPGA card,in a connector that it have f...
