Re: custom USB controller adapters

I got one atmega32u4 (that's the one with proper USB if I'm not mistaken) and a few 328p (which are dirt cheap). My rough idea is to use the 32u for development and the eventual adapter, but then use the 328p for general conversion/non-USB stuff. Does anybody have an Eagle library/part for the shape...

Re: custom USB controller adapters

After googling around I think it's a bad idea to put a DC jack without adding a voltage regulator circuit or it might damage controllers. I guess I can just change it to holes to solder a battery holder on the back of the PCB.

Re: custom USB controller adapters

I've been playing with Eagle while I wait for the Nano to arrive. I had the idea of making a DIY PCB to test joysticks in Neogeo/Arcade format, which actually allows for 9 buttons if using non-standard pins (so I assigned to a "home" button we could use for OSD). I've added a standard DC p...

Some interesting finds... This guy built his own SNES controller from scratch (including 3D printed shell): http://blogfarts.blogspot.hk/2016/11/open-sourcing-snes-controller.html And linked from that page, here are nice schematics for the discrete circuit: http://www.raphnet.net/electronique/arcade...

Re: custom USB controller adapters

I wonder if the MCU could handle four connectors sharing the ground, VCC, and CLK. Then it could make a USB adapter and multitap :) But my first priority is to explore the SNES standard a bit, I find it interesting to wire a discrete encoder. I will need a male connector, fortunately many original c...

Re: Arcade cores

I have an idea... would it be possible to integrate some OSD commands into this core? Then it could be used to write a fancy customizable alternative to menu.rbf :)

So e.g. it runs on startup and presents a nice screen with plenty of graphics, joystick tests, etc.

Re: Arcade cores

From a developer's perspective, there's the question of why write for this platform instead of a more common one like the NES. Granted it might be harder, but install base won't be a problem.

Re: custom USB controller adapters

The goal would be to make a lag free adapter which could support as many legacy formats as possible then bliss-box posted above should be exactly what you want. It's too expensive. At ~$120 it costs the same as two Retro Freak adapters; that also does what I want :) Or I could get individual adapte...

Re: custom USB controller adapters

Fair enough. I own lots of controllers, including several legacy ones for retro systems. I care about quality of the controller and also in using the best controller for a given game. I also have systems which do not have USB (e.g. Arcade SuperGun) and I sometimes build my own joysticks with DE15. I...

custom USB controller adapters

One of my favorite USB controller adapters out there is the Retro Freak's, but unfortunately it's very expensive ($60) and doesn't allow using Neogeo/arcade controllers. Looking around it seems that most USB adapters are in the $20 to $25 range, so it's also pricey to get an adapter per system. That...

Re: SDRAM board

However, if there is no assurance of supporting more memory in cores, then it would be a waste of my time. I wouldn't just go making a new IO board without it being something that people have been asking for, so not everyone shares your opinion of making this as cheap as possible. Surely you ought ...

Re: MISTer on DE0-nano?

Would this use the same SDRAM board as the DE10?

If so, It means they could maybe be made in higher volumes as it's the biggest piece needed by cores. I also guess the VGA could be made as a cheaper cable for the DE0 to reduce costs / complexity for DYI?

Re: Joystick testing thread

Many older arcade games used a 4-way or 2-way joystick. Most arcade sticks can be fitted with a "restrictor gate" for this purpose, so that you can't physically hit diagonals. Of course for normal controllers this hardware trick won't work.

Re: Joystick testing thread

OK, did testing on that INEXT Pad. Here are the results: The DPAD is mapped to two analog axis, with Axis 0 being left/right and Axis 1 being up/down. 127 is the middle point going from 0 to 255. All this looks bog standard so I'm surprised that your gamepad doesn't work. From your earlier descript...
