MiSTer FPGA Forum

I was finally going to my dream MiSTer kit from you, but it seems like you only sell it with SDRAM now... (BTW, bug report: the announce still says "This kit doesn’t include DE10 nano or SDRAM module.", even though that is no longer true. Is there any chance you would consider still selling a kit without SDRAM? Yes. You are the 3rd perso...

I have not tried. Probably not. But I am developing a RTC module for my setup.

The whole issue by the way, is not about the flaw itself but about stubborn refusal to admit that it exists, plus the misleading and dishonest info on the product's webpage . I don't know what you win spreading bullshits here and in other forums against me: https://spectrumcomputing.co.uk/forums/viewtopic.php?p=46712#p46712 There is no dishonest i...

Use these gerbers instead. I changed the orientation of the board

My adapter has not any issue. all adapters have the same issue. This is surreal :) Unfortunately I might actually need one of these adapters soon, so still would like to find out what the score really is. It seems impossible to do so in this bizarre thread, so if anybody has one and uses it to display composite on a CRT I'd appreciate if you could...

How is the integration with the framework? Hopefully it's not too intrusive so may be submitted as a pull request?

According with Sorgelig is not on framework
https://www.atari-forum.com/viewtopic.p ... 89#p384089

And he's not interested to support this feature. So we must do a fork

How will this work with PAL/NTSC selection? For example NTSC (60hz) output on the core but PAL subcarrier freq on VSYNC (PAL60)? An extra core option? To be honest, I always thought the core descriptions were misleading as really they select 50/60hz, not PAL and NTSC. In this case it would be very confusing. Yes. The core has an option to activate...

akeley wrote: ↑Thu Sep 17, 2020 9:58 am You miss the point completely. Perhaps all adapters do have the same issue, I don't question that. But that means there IS an issue. And there is no mention of that issue on your website, which instead promises the output to be pure and same as the original.

My adapter has not any issue. You really missed the point

If you talk about "fixing it" then how can it be "normal"? Your explanation in the tweet says it's normal for FPGA, but this obviously does not make it any less of a problem. Unless you are talking about fixing the flaws inherent to composite, which were present on original hardware (though then it wouldn't be "same as ori...

It would help to have a core generated colour subcarrier clock to use instead of external timing but since it would interfere with the framework, it's likely never going to be added I have added to my hardware but the problem it's the main team of MiSTer don't want to adapt the cores to generate this signal. This solved on other FPGA products I se...

I have ordered with these files on jlcpcb.com

Just ordered another complete slim setup for a friend. He needed the floopy drive sound & db9 port :-) (thanks again !) BTW; can you confirm that when not using a db9 splitter, I can use a single Amiga / CD 32 / Genesis gamepad out of the box ? (with the specific core build of course) Yes. The DB9 splitter is only for 2player. For one player y...

Hello Antonio! I’ve recently put together a db9 kit on the de10 nano and have gotten most things up and running. Im only unning into a couple issues. I have not gotten 2 players to work in the genesis or mega cd cores. The best i get out of the splitter for 2 player modes is duplicated input across both player 1 and 2. Snes games work perfectly ho...

Just restocked in 2 units

But the main point is that there is a flaw in the first place. Your description on the website does not mention it at all. You also said it's possible to correct it via hardware, and will do so in the next edition. Selling the inferior unit in this situation does not seem fair. If I just bought it it'd be useless because then I'd have to buy anoth...

I would like to see an example of this if someone can show me? I have a feeling the issue has been somewhat over-hyped, I have not noticed the problem on my own adapter, though admittedly it's using a different encoder IC. Yes. This guy is seller of MiSTer stuff and it seems he does to attack competitors. As I explain on that email, the problem is...

Yes, that's the idea. And the switching time is measured in nanoseconds, so you can read both ports very fast.

Hi Antonio , I would like to understand how a DB9 port with only 9 pins can be read as two separated controllers You have the hardware here for schematics and pcb files. It's open hardware. https://github.com/antoniovillena/MiSTer_DB9/tree/master/Hardware Basically we have 10 pins. The 10th pin is on shield and for this reason we call SNAC8 instea...

Yes. Very professional. Congratulations

Hi Brettster

Follow his BOM:

https://github.com/dshadoff/MiSTer_PCE- ... v3/bom.csv

I have not changed his designators

which I thought was a bargain!

Yes. That's without PCBA. It's a lot of work mount the SMD. So see if you can order SMD mount and then you mount the connectors yourself

In the project, I had published bom.csv and assembly.csv files as needed for JLCPCB's PCBA process (referencing the design contained in the repository). The BOM is human-readable... https://github.com/dshadoff/MiSTer_PCE-SNAC/blob/master/SNAC-PCEv3/bom.csv A new assembly.csv would likely be needed for the new design though (but JLC has instruction...

I don't know whether there's any circuitry between the DB-9 and user I/O - I suspect there is. But the plans are public, and don't require any tools which cost money, so whoever created the DB-9 version of hardware can certainly make use of the important parts if they wish. Yes. There are protection diodes (BAT54s). I have modified your version to...

I got the bundle of 5 adapters from Antonio and I'm using the PC Engine adapter and I have about 5 different PC E joypads Avenue 3, Avenue 6. Core grafx pad and white PC E pad with turbo switches none of the turbo switches work all will work as a 2 button pad. when SNAC is enabled, Except the white turbo switched one, which does not work at all, b...

However there's no more mention of the buzzer for the floppy drive sound, is it still provided ?
Thanks !

Hi mahen

Buzzer for DRIVE version is not provided because increase height. But I plan to add in a future

dshadoff wrote: ↑Sat Jul 18, 2020 10:08 pm Or one converter board (per machine) to do all of the above.

But nobody is selling that. I have no problem because I sell cheap adapters. But with official IO all related with native controllers is expensive and complicate. I think the solution is include level shifters on official IO

The main problem with official SNAC is there are not level shifters on IO board, so you need an extra board to do level shifting and another one to change USB3 connector to native one

Does that mean only the Genesis controller works on all cores and for NES, SNES, PC Engine and NeoGeo controllers they only work on their own cores with SNAC enabled? Yes. To guarantee zero lag you need to use native controller. For example if you want zero lag with the NES core you need to use NES controller with SNAC. But in our fork we have imp...
