@mitu Thank you, that was the problem!

I may have missed something in the documentation. I thought I had to configure input twice, once for the main box, and once for the second box. But configuring for the second box, even with all the buttons plugged into the same slots, caused the important buttons on the main box (coin, 1P, 2P) to be forgotten.

@donkeykongcab Hey...hope you can help me?

I have a cab set up with a Pi3b + arcadergbpi to gamma...plus an optipac...

I am having trouble getting the inputs working...it looks like you have a similar set up (instead of a trackball and spinner) Im using a wheel and pedal (spinners basically - but optical from an original arcade machine). both register as mouse 2 and mouse 3....but only one at a time appears to work via retroarch...any pointers?

Thanks,
Sean

@dankcushions said in Need lr-MAME2003 core options for config file:

input_overlay_enable_autopreferred = "false"

Tried this, doesn't work from the local overlay/scaling file that is associated with the rom in the rom folder.

Seems MAME2003 is not reading this file for the overlay size specs anymore. Previously, you had to make a config file that pointed to the overlay, then the scaling and and opacity was set there as well. Did something change because it's not reading this file for those settings anymore, even with the auto-scaling "off" in the On-Screen Overlay menu. The overlay shows, but it's scaling is all screwed up because it only reads the settings in the core retroarch.cfg.

I does read everything else in this file though.

005.zip.cfg

video_shader = "/opt/retropie/emulators/retroarch/shader/arcade-bezel-shader/crt-pi-vertical.glslp"
video_shader_enable = "true"

input_overlay = /opt/retropie/emulators/retroarch/overlays/arcade-bezel-overlays/005.cfg
input_overlay_enable = true
input_overlay_opacity = 0.900000
input_overlay_scale = 1.000000

custom_viewport_width = "741"
custom_viewport_height = "933"
custom_viewport_x = "589"
custom_viewport_y = "70"

video_scale_integer = false
input_overlay_enable_autopreferred = true

**** nevermind... I see what's changed... it's PORTRAIT now. It's reading that setting just fine.

I deleted the old retroarch.cfg and allowed it to rebuild a new one, and there it was.

@wavfact Good to know, thanks for sharing your solution.

@tmoe01 said in Dip Switch help:

Now my task to tackle will be figuring out how to flip the screen for player 2.

this part might involve dipswitches, other clones, or maybe the service menu. look for options to enable cocktail mode, etc.

@dankcushions yeah, from a libretro implementation POV, but afaik lr-mame2003-plus would still be a far better choice than lr-mame2003 if libretro features are what you are looking for.

@shoebox low voltage can cause big problems, underclocking is one of them. I would skip the canakit power supply as they are one of the less reliable and go straight to the official raspberry pi power supply.
