pacman.zip.cfg doesn't get called

we will need your aspect ratio index for a start at least type.

if your roms are in mame-libretro

less  /opt/retropie/configs/mame-libretro/retroarch.cfg | grep aspect_ratio_index

if your roms are in arcade

less  /opt/retropie/configs/mame-libretro/retroarch.cfg | grep aspect_ratio_index

if this index number is 21 its wrong

schmiddyman

@grant2258 my roms are in arcade, but I only have the default retroarch.cfg in it which inherits from ALL. In that config file the aspect_ratio_index is commented out. What value should I set it to?
@mitu I was successful setting the rotation in the rgui menu under video and saving it . But of course it would be more elegant to do it the "tate" way. That would save me some work to do it for every single game.

@schmiddyman The docs say that in order to get the games to automatically rotate, you'll need to enable the tate mode in the core options for mame2003, but disable the video_allow_rotate option. The core options can be set from RGUI (and are automatically saved) and you can add the video_allow_rotate = false in the arcade system's retroarch.cfg. Remove/rename your ROM .cfg file and try to see if that works.

grant2258

first of all you want to update your mame2003 since the retropie binary is old grab it from the libretro build bot from here or compile it yourself.

cd ~
wget https://buildbot.libretro.com/nightly/linux/armv7-neon-hf/latest/mame2003_libretro.so.zip
sudo unzip mame2003_libretro.so.zip  -d /opt/retropie/libretrocores/lr-mame2003/
rm mame2003_libretro.so.zip

your index number should be 22

aspect_ratio_index = "22"

@mitu ive tested this video_allow_rotate = "true" is fine to use all is working well when you update the aspect ratio index the 21(square now) will stop tate mode working properly

schmiddyman

@grant2258 Yeah, I upgraded the mame2003 and the tate option works!!! I have the aspect_ratio_index set to 21. If I set it to 22 I get a black screen.

grant2258

@schmiddyman what version of retropie are you on ? set it back to 21 if you like but the settings -> video-> aspect ratio should be reading core provided when you check it. Maybe one of your over rides are causing issues.

schmiddyman

@grant2258 V4.4

grant2258

ill bow down to @mitu for advice on how to setup your aspect ration index in retropie. I personally done it through retropie setup.

I usually use retroarch from it native environment it ok to edit the confings there if you choose to or change option in RA because it saves the settings on exit.

Rretropie configs are best done through retropie setup as it runs retroarch in a different kind of environment so i wouldn't advise hand editing unless you know what your doing

mitu

@schmiddyman Why do you set aspect_ratio_index explicitely ? As @grant2258 said, you should leave it as 'core provided', there is no need to set it yourself. One use is when you want add bezels and you'd want to provide a custom resolution, but if you're not, then I don't see why you'd override the defaults (core provided).

schmiddyman

@mitu It works for me when I don't specify it. The only problem is that it rotates to the wrong direction for my coffee table setup. I ended up having to define rotation for every single game I want to play in vertical mode.

grant2258

rotate your monitor then

schmiddyman

@grant2258 I have a fixed setup. I cannot rotate the monitor. Have a look at the pic above

grant2258

you can rotate it 180

schmiddyman

@grant2258 I don't understand what you mean. I can rotate the whole screen in /boot/config.txt. But the rotation of tate mode is always relative to the current orientation and will rotate 90 degrees to the left. Looking from the front of my cabinet, player 1 is always left and player 2 right. For the horizontal mode the two players are on the front side. I need to switch my modes between horizontal and vertical mode all the time because of the particular roms.

grant2258

the rotation for tate made rotates right ie you have to rotate your monitor right to see the image. If you mirror this it will in the config it will effect this rotate.

schmiddyman

@grant2258 If you rotate your monitor physically to the right, the screen rotation goes to the left. Changing the config.txt -> display_rotate to 2 doesn't change the direction of the tate rotation. I tried this already.

grant2258

im not sure what your issue is here the tate mode does rotate right this is what arcades do
