Hi, and welcome to my page where I cover the gadgets I make and sell.  

Updates and random info below. I also post a few updates on https://twitter.com/IrkenLabs.

(MiSTer) DE10-Nano JAMMA Expander

It seems like everyone and their mother is working on a different types of JAMMA solutions for the MiSTer project, and I am too :)

 

I haven't settled 100% on a name yet, but for now the working title is simply "JAMMA Expander", as it expands the DE10-nano to work in a JAMMA cabinet.  It doesn't have a zillion features, but aims to make running MiSTer in a cabinet as easy and clean as possible.  If you want a really good "multi-pcb" for use in a cabinet, but don't feel like a taking on a project - this may be the board for you. 

This board uses the HDMI output of the MISTer, so both video and audio will be as good as it can get.

Some specs

  • 24 bit color, coupled with a high quality DAC and RGB amplification.
  • It has a decent audio amplifier for MONO audio, but you can also toggle a switch to get line level stereo via RCA if you have a stereo amplifier in your cab.
  • Hassle-free firmware updates via micro-SD, very much the same way as the Jammafier and the JVS-PAC 2
  • an OLED for diagnostics

You mount the DE10 on top of this board, not under - so fitting it in a cab should be very simple, and it's also easy to remove the DE10 should you want to use it for something else.

Availability should be sometime this summer ;), price is TBD.

Winter Update - Happy 2021

A long overdue winter update!  My lab is now operational and there is actual r&d happening :)

MiSTer!

I'm happy to report that the JVS-PAC 2 and MiSTer are now friends, and it makes for a very easy and nice setup!  I've added a tutorial on getting a MiSTer up and running in the JVS-PAC 2 section.  To make things more plug and play, I've updated the default key-mapping for Player 2 Button 5 to "E", which is the MAME standard and also used in Jotego's fantastic cores e.g. the CPS1 - i.e. no complicated merging/unmerging of devices or remapping of input.

If you already have the JVS-PAC 2, all you need in addition to the DE10-nano is an SDRAM module.

 

For Jamma cabinets, a little more hardware is involved in making the DE10-Nano cabinet friendly, but I'm confident there be solutions for that soon :)

Stock Levels 

 

Stock levels are healthy, and I don't expect that to change anytime soon.  

Fall update 2020

There has been close to zero R&D last few months, and it will unfortunately continue like that until sometime in December.  I started a new job this summer, and right now I'm in the middle of moving out of our apartment in the city centre  to a proper house with garden on the outside.  I will miss having coffee shops and stores minutes away by foot, but look forward to having a dedicated office/lab, garage, garden etc.  As if that wasn't enough, I'm also getting my drivers license and a car, which is kind of a thorough process here in Norway.  Anyway, I expect to be done with all of this in December.

Store closing 1 - 15 October

I'm away on business a couple of weeks, and instead of getting a backlog of unshipped orders I will simply close the online store the first weeks of October.  The store will likely also close for a week or two in November.

MiSTer?

I've gotten a few emails about JVS-PAC 2 not working with MiSTer, and I can confirm it is indeed problematic at this point.  I got a MiSTer setup myself, and I'm positive that it will work some time in the future.  

A possible fix/workaround will be to implement the planned gamepad mode for the JVS-PAC 2, but given all the problem-reports I've been reading for a lot of different devices this is just a theory.  A good test to check if a setup is working properly is to load up a 2 player 6 button game, enter test mode and press all buttons for all players at the same time, while move the joysticks around.  I expect this simple test would reveal issues with a lot of MiSTer setups..

From my perspective, the problem is mostly with the input model of MiSTer, they could learn a couple of lessons form the MAME project..

Stock levels

Except the A1 scaler, no stock shortage in sight for the foreseeable future.  I've initiated another run of the A1 scalers, but may run out of stock until it's completed.
