Hi

I've been making control panels using Pi Pico as they are dirt cheep and programming through Circuit Python is easy.

I've had an original Tatio spinner lying around for years, and I've never got it to work - as I've discovered reading here, its an active high device and therefore I can't use it with the U-Hid that cam with my trackball, nor the trackball pins on my iPac2.

My thoughts have turned to the Pi Pico - and can I use it to interface the spinner without buying an Opti-pac? My gut says yes, but my head isn't there yet

Turns out both harneses are defective, using some arduino cables, the acceptors work fine.

Check your mamewah.log file.

Make certain the hard drive letters haven't changed. Three seconds sounds like enough time for screensaver or slideshow to kick in, maybe it is looking in the wrong locations for vids/snaps. When you quit, it could be looking at the wrong location to start explorer.exe

Is it logging onto the right user?

Check other settings in BIOS to see if it all seems appropriate (as it was wiped to default when the old battery died).

Hopefully the log file will shed some light.

It is not, before price gouging you could get a DE10 nano for educational purpose for $79.

Considering inflation during those years, I'd say that $99 is ok and maybe I'll get one, but I won't spend a single cent more on it.

Before there was no GroovyMiSTer

Can you attach mednafen.cfg?  I tried on 2 different machines with success.
Which are the last version without this bug for you?

mednafen-1.31-emu4crt-A20e-win64 is no problem

the newer version i only change video.resolution_switch,all other is default.

i test 2 pc with crt_emudriver 12.6&16.2.1 on win7,both the same.

I'm gonna turn this:

Into this:

meh, you do what you can to make it work sometimes. 

i have a bunch of Minimus AVR boards that i got back in the Kade days... 10 some odd years back, that are already setup to take pin signals going low and turn them into various keyboard key presses. (all configurable) shows up as a USB keyboard to windows. shame they didn't do more... it's was looking like a solid project.

in any case, a program called "atmel flip" will update the bootloader of your arduino so you can upload a keyboard HID file into it, so it just boots directly to HID mode. https://www.instructables.com/How-to-Make-a-Arduino-HID-Keyboard/

I got a working acceptor already with the board I posted earlier, the ardionos I get locally, are either atmega 328 or smd something like that,both are not compatible to turn them into hid keyboards.  To bad the original v6 wont work, I really trusted that payway company, but they did not do a good job. I only canhope to get my money back, minus the shipping. I hate when people do that, I mean I'm pretty sure all they did was upload the old firmware and they didn't care about testing them, even though they said they tested them out, its a lie, because once they got to my home, they magically wont work. Freaking liars.  If I get my money back , I'm buying another acceptor.
