MiSTer FPGA Forum

I'd be interested in answers from someone knowledgable in electronics to MickGyvers questions as well. My electronics knowledge is not very deep ;-) From what I see, there are two new ones in the top row which used to be 10uF, 0.1uF - 10uF, 0.1uF for the 2.5 module. Given that my understanding is that they are bypass capacitors, I'd guess that thi...

Thanks for the new version, I have to build a few for my MiSTers!

What is the correct layer stackup of the PCB for controlled impedance? JLCPCB supports two stackups, JLC7628 with 0.2mm prepreg and JLC2313 with 0.1mm prepreg, which one to use?

Also what capacitor configuration is recommended for this version?

I am indeed working on a gameport to USB adapter. I'm currently implementing the Microsoft Sidewinder range. Since you have implemented GrIp support in the core, could you consider implementing the Sidewinder Precision Pro or 3D Pro? They use a similar principle, button1=clock and button2=data. The Sidewinder range need a trigger to send a data pa...

After looking it over, it seems most joysticks do have the timer on board. The lack of an 8th wire though will prevent it from ever being an ideal solution, missing one axis or button. IMHO the best route to an ideal scenario is to get a good gameport to usb converter (I believe McGyver is designing one) and work towards adding a second analog sti...

It worked with direct pin to gpio on mt32-pi with atari st core Could you share also ao486 source with support MIDI via the USER IO port to test? Thanks! Thanks to the correct MIDI baudrate now also for the ao486, I made a test version with IO MIDI for the ao486 core. The sources can be found here: https://github.com/MickGyver/ao486_MiSTer A compi...

RPi4 sounds pretty good! I think RPi3 can maybe do OK as well. My RPi3 I was testing with gets that little lightning bolt symbol indicating insufficient power even though I use adapters with 3amp. Maybe it is defective :( Keep in Mind, that ANY RPi solution is going to need some sort of external DAC unless you use HDMI for sound unless you want it...

In my case I want to use ScummVM on my 15KHz CRT. I managed to get a non-cropped image with these parameters (352x240px):

video_mode=352,26,34,73,240,4,3,15,7383

It's offset slightly to the right but otherwise it works great.

Hi! I'm trying to get a good image on my CRT using the vga scaler at 320x240p resolution. I'm currently using these settings: video_mode=320,8,32,24,240,4,3,16,6048 The image is centered both horisontally and vertically on my CRT but the image is cropped on both the left and right sides. Could a kind soul explain what I would need to change in the ...

Code: Select all

[scummvm]
filtering=false
gfx_mode=1x

Thank you very much! I have it working now. Just need to find a good resolution for my TV, 320x240 is clipped on the sides by overscan, 384x224 is not clipping but doesn't fill the screen entirely.

Yes, you must use vga_scaler=1.

The IO board VGA out will work, but I'm not sure about direct video...

Thanks, where is the scummvm.ini stored? I don't have another monitor to test with where I am, so I can't set the settings needed in scummvm for it to work.

Copy ScummVM_2_2_0.sh to ScummVM_2_2_0_320x200.sh Edit ScummVM_2_2_0_320x200.sh echo "Setting Video mode..." vmode -r 320 200 rgb16 You can run in 320x200 mode if you must first boot into 640x480 mode and make changes: Graphics Mode : Normal (no scaling) Render Mode : default [ ] aspect ratio correction [ ] Fullscreen Mode [ ] Filter Gra...

Small correction, the daemonbite adapters are DirectInput (DInput) devices.

Please do, that would be fantastic!
