MiSTer FPGA Forum

On the digital IO board, both the TOSLINK and mini TOSLINK sockets should be providing digital optical audio out simultaneously.

Are you sure you are not just hearing the high frequency noise generated by your flyback transformer inside the monitor?

Not sure how I missed this addition to the M72 core, but Martin Donlon @wickerwaka has added Gallop : Armed Police Unit to his IREM M72 Core. Commit here: https://github.com/wickerwaka/Arcade_m72/commit/aace5d2c42c3921d0c5447074b6428418fbf3902 IREM M72 Core GitHub: https://github.com/wickerwaka/Arcade_m72 Gallop Armed Police Unit.png M72 Gallop Arm...

Awesome news to see Sergey is safe and has been able to post a development update on the Saturn core!

Looking at the MiSTer Wiki the Atari ST/STe core requires a memory clock speed of 96MHz, try running other cores from the link below that use 96MHz if those fail your SDRAM is unstable when down clocking to 96MHz.

Jotego also has a dedicated 96MHz SDRAM test on his GitHub.

For some Friday arcade fun, fire up your MiSTer's as Jotego has released Pang! for everyone to enjoy

Pierco (Pierre Cornier) while on vacation has been using just his phone to work on Chameleon. From Pierco's Twitter: I'm done with audio & sprites for the Jaleco Chameleon simulation. It was an easy one but still the first one I did entirely from my phone during a vacation. I will try to turn it into a MiSTer core in two weeks. Jaleco Chameleo...

If you need a recommendation, for a cheap OTG hub these are used by many for low cost MiSTer builds:

You need to connect via the OTG Micro USB socket on the DE10-Nano, using an OTG USB hub.

Looks like the R-Type core is now in beta:

Some information from Sorgelig about how the white noise on the menu screen is generated. Sorgelig Wed Nov 06, 2019 7:37 pm Noise screen comes from true noise produced by FPGA. It's NOT pseudo random generator using some calculations. So it depends on temperature of chip and initial state. Sorgelig Wed Nov 06, 2019 11:20 pm Basically it's cyclic co...

A list of SDRAM memory requirements for individual cores are listed on the MiSTer wiki here:

Just for future reference I have attached the Terasic DE10-Nano revision document, this documents the changes made by the manufacturer to each revision of the DE10-Nano board. The document also explains how to tell which revision of DE10-Nano you have.

The red LED provides optical digital out, via the 3.5mm audio jack.

You need a mini Toslink cable connected to the 3.5mm audio jack then into a DAC to use this method for audio output.

Looks like R-Type is currently being worked on!!

Please be aware the IREM M72 core is a work in progress, and still being developed.

As far as I am aware no MiSTer project specific test suite exists, however the DE10-Nano manufacturer Terasic in a post on the forum, recommend the following should be undertaken on a new DE10-Nano to confirm all is functioning on the HPS and FPGA hardware of the main board. Important notice: Before implementing your MiSTer project on DE10-Nano, pl...

Yes.

Use M3 cap head bolts these will fit neatly into the mounting holes on the fan.

They are M3 sized for bolts and nuts, maybe go with 25mm length, as the fan you are going to use is 20mm thick, you need to pass through a 1.6mm thick PCB.

Josh Bassett @nullobject has released Gaia Crusaders for the CAVE 68K Core, It is now out of beta testing and available for the MiSTer FPGA. The story involves the world being destroyed by demons in the year 20XX. Chosen warriors, the Gaia Crusaders, are sent in by an ancient spirit to destroy the demons and rebuild the world. If you wish to suppor...

Does this offer any benefit over a module that would only run at 130 MHz? Not really. Every core has a different specific MHz speed requirement. Higher clock speed does not mean it is any better, the memory actually needs to run reliably at many different fixed MHz values depending upon the specific core being used. The current highest MHz require...

Perfect for some weekend beat 'em up arcade fun, Vigilante has now been publically released by Jotego Vigilante from 1988 was developed and published by Irem in Japan and Europe, and published in North America by Data East. It is considered as a spiritual sequel to Irem's earlier Kung-Fu Master (1984). The game takes place in downtown New York City...

Sure, this is not a problem, I am happy to setup a dedicated sub forum for this type of activity.

If those users who wish to start this brainstorm an outline and flesh this out further.

Audio here we come! Another update from Pierco:

I have some very clear and fond memories of playing Crypts of Terror on my best friends Dad's Atari 400 in their living room on the 'big' TV, playing on the Atari in the living room on the 'big' TV was only allowed on Friday nights. Looking back I can see why these early explorations into computer gaming formed strong memories as this was also next...

It might be an fault with your DE10 Nano, if two different expansion boards are producing the same result. As this is not a normal or expected behaviour.

If the DE10 is reading a button press from the KEY0 button on the DE10 Nano board this message does appear. Try just booting the DE10 Nano on its own, do you get the same result?

Do you have an IO board connected?

Helpful hint

Pierco (Pierre Cornier) is currently working on Rod Land. From Pierco: There's no sound yet, no VGA, a lot of glitches and big slowdowns but it is playable! The core is available on Patreon for his supporters. https://www.patreon.com/pierco Rod Land, known in Japan as Yōsei Monogatari Rod Land (妖精物語ロッドランド, lit. "Rod Land: A Fairy Tale"),...
