What's the correct aspect ratio I should be using as a config for a HAPP / VISION PRO 19" LCD arcade monitor for MAME Horizontal / Vertical games

@thorr69 I'm a developer for mame2003.

The core is set to rotate the screen image automatically so that vertical and horizontal games display upright on a standard monitor or tv without the need to turn your monitor.

This is not the behavior of an actual arcade machine however, vertical games would have physically mounted the monitor sideways in the cabinet yet the image is still shown normally to the player. So it displays in a 90 degree rotation.

Tate mode is designed for a user that is going to physically rotate their monitor for vertical vs horizontal games everytime. See this video around 3:30

If you are mounting a monitor in the vertical position permanently then you want to rotate the entire system so emulationstation and everything else shows properly.

Yeah, I know. I've done all of this and have a vertical system. My reply above was an aborted post. I got phone call when I started and must have hit Submit when I meant to Discard. I came back and saw it and tried to delete it, but the time window expired and I could no longer change it.

@thorr69 no problem, just trying to clear up some of the rotation confusion.

The op needs to remove any aspect ratios they may have altered in their cfgs and set the systems rotation in config.txt then everything should work.

Yeah, this is where I was going, too. I use a rotatable Dell 19" 5:4 monitor, so I manually turn my screen for vertical games. The setup is simple: Use TATE mode as a Core setting and disable Auto-rotate, then set rotations as Game overrides where needed. No other changes were required. The default values worked just fine on every other setting. I've rebuilt it several times and just those two settings are all I have to change to make it work.

@dankcushions Understood. I did not know this and was just trying to be helpful. I've been running MAME since 1998 on all 5 of my dedicated MAME cabinets with PC's.

I just assumed they carried over. Sorry.

So first went to ssh to delete any modifications I made. Proceeded to pop in my SD card into my computer and I modified my boot config text as suggested and added "rotate_display=1" did absolutely nothing. The game is oriented in the wrong orientation, and It's to be used for a monitor mounted vertical.

Here is my boot.cfg (scroll to bottom you can see where I added "rotate_display=1":

I don't understand TATE mode I've clicked on the link can someone explain it to me here instead of the wiki ?

through the location of ssh

/opt/retropie/configs/all/retroarch/retroarch-core-options

My file looks like this:

cap32_autorun = "enabled"
cap32_Model = "6128"
cap32_Ram = "128"
cap32_combokey = "y"
fbneo-diagnostic-input = "Hold Start"
fuse_machine = "Spectrum 128K"
gambatte_gb_colorization = "custom"
mame2003_skip_disclaimer = "enabled"
mame2003_dcs-speedhack = "enabled"
mame2003_samples = "enabled"

@romstar my apologies, I mixed up the wording... you'll use one of these. Each one rotates the image 90 degrees, pick the one you need:

display_rotate=0
display_rotate=1
display_rotate=2
display_rotate=3

Then remove the # if front of:

disable_overscan=1

OK FINALLY!! Figured it out (with the help from you guys).... Below is what I did hope this helps others:

Here's where my file was located and what I did :

Through access ssh the path is : /opt/retropie/configs/all/retroarch/config/MAME 2003 (0.78)

Within that folder I saw "MAME 2003 (0.78).opt" file

right clicking it & hitting edit brought up the following of my file:

mame2003_art_resolution = "1"
mame2003_brightness = "1.0"
mame2003_cheat_input_ports = "disabled"
mame2003_core_save_subfolder = "enabled"
mame2003_core_sys_subfolder = "enabled"
mame2003_dcs_speedhack = "enabled"
mame2003_dialsharexy = "disabled"
mame2003_display_artwork = "enabled"
mame2003_display_setup = "disabled"
mame2003_frameskip = "0"
mame2003_gamma = "1.0"
mame2003_input_interface = "simultaneous"
mame2003_mame_remapping = "enabled"
mame2003_mouse_device = "mouse"
mame2003_nvram_bootstraps = "enabled"
mame2003_rstick_to_btns = "enabled"
mame2003_sample_rate = "48000"
mame2003_skip_disclaimer = "enabled"
mame2003_skip_warnings = "disabled"
mame2003_tate_mode = "disabled"

I changed the bottom line to mame2003_tate_mode = "enabled" which ultimately resolved my issue. now The vertical game is finally displaying the way it should on my HAPP Vision pro monitor mounted vertical !! At some point I'd like to build a vertical only list of games and have the menu / retropi running exclusively in vertical mode.

glad it's working! interestingly, the reason this file is in this location, and not updated correctly in /opt/retropie/configs/all/retroarch-core-options.cfg as it should do in retropie, is a side-effect of your /opt/retropie/configs/all/retroarch.cfg being non-default. specifically the setting
global_core_options = "false"
should be
global_core_options = "true"

i would encourage you to resolve this by replacing the entire /opt/retropie/configs/all/retroarch.cfg with /opt/retropie/configs/all/retroarch.cfg.rp-dist (if the latter doesn't exist you can generate it by updating retroarch via retropie_setup > manager packages > core packages > retroarch). or you could just change the one setting, but i would imagine there are other non-default settings hidden in there...

obviously after you've done this you'll have to make the same tate change via /opt/retropie/configs/all/retroarch-core-options.cfg

I knew it would change your life. I would not recommend trying to make the whole of retropie itself work in vertical mode yet, though. I stayed with my rotating monitor because rotating emulationstation causes performance issues. I believe it also became more difficult to rotate emulationstation on the Pi4 because the option was deprecated. I stayed with my Pi3b for my vertical MAME games for that reason and hope that a good solution for a fully vertical system presents itself later.
