Issue with getting Odyssey2 to ouptut

Unread post by LeKrang »

Hi everyone,

I have been having an issue with the Odyssey 2 core where when I try to launch it, my screen looses sync and there is basically nothing I can do except cold reboot to get back to main menu.

I have my Mister.ini file configured like this:

key_menu_as_rgui=0 ; set to 1 to make the MENU key map to RGUI in Minimig (e.g. for Right Amiga)
forced_scandoubler=0 ; set to 1 to run scandoubler on VGA output always (depends on core).
ypbpr=0 ; set to 1 for YPbPr on VGA output.
composite_sync=0 ; set to 1 for composite sync on HSync signal of VGA output.
vga_scaler=0 ; set to 1 to connect VGA to scaler output.
hdmi_audio_96k=1 ; set to 1 for 96khz/16bit HDMI audio (48khz/16bit otherwise)

; 2 - use 0.5 steps of scale.
; 3 - use 0.25 steps of scale.
; 4 - integer resolution scaling, use core aspect ratio
; 5 - integer resolution scaling, maintain display aspect ratio
vscale_border=0 ; set vertical border for TVs cutting the upper/bottom parts of screen (1-399)
;bootscreen=0 ; uncomment to disable boot screen of some cores like Minimig.
;mouse_throttle=10 ; 1-100 mouse speed divider. Useful for very sensitive mice
rbf_hide_datecode=0 ; 1 - hides datecodes from rbf file names. Press F2 for quick temporary toggle
menu_pal=0 ; 1 - PAL mode for menu core
hdmi_limited=0 ; 1 - use limited (16..235) color range over HDMI
; 2 - use limited (16..255) color range over HDMI, for VGA converters.
direct_video=0 ; 1 - enable core video timing over HDMI, use only with VGA converters.
hdr=0 ; 1 - enable HDR using the BT2020 color space (faux-HDR, use color controls to tweak).
; 2 - enable HDR using the DCI P3 color space.
; 3 - enable HDR without color space conversion.
fb_size=0 ; 0 - automatic, 1 - full size, 2 - 1/2 of resolution, 4 - 1/4 of resolution.
fb_terminal=1 ; 1 - enabled (default), 0 - disabled
osd_timeout=0 ; 5-3600 timeout (in seconds) for OSD to disappear in Menu core. 0 - never timeout.

vga_sog=0 ; 1 - enable sync on green (needs analog I/O board v6.0 or newer).

; 1 - enables the recent file loaded/mounted.
; WARNING: This option will enable write to SD card on every load/mount which may wear the SD card after many writes to the same place
; There is also higher chance to corrupt the File System if MiSTer will be reset or powered off while writing.

; lastcore - Autoboot the last loaded core (corename autosaved in CONFIG/lastcore.dat) first found on the SD/USB
; lastexactcore - Autoboot the last loaded exact core (corename_yyyymmdd.rbf autosaved in CONFIG/lastcore.dat) first found on the SD/USB
; corename - Autoboot first corename_*.rbf found on the SD/USB
; corename_yyyymmdd.rbf - Autoboot first corename_yyyymmdd.rbf found on the SD/USB
;bootcore=lastcore ; uncomment to autoboot a core, as the last loaded core.

; 10-30 timeout before autoboot, comment for autoboot without timeout.

; Option to load the custom font. Format is plain bitmap 8x8.
; Supported sizes of font:
; 768 bytes - chars 32-127 (only alpha + numeric)
; 1024 bytes - chars 0-127
; 1136 bytes - chars 0-141
; up to 2048 - only chars 0-141 will be used.
; if first 32 chars are empty (for sizes 1024 bytes and more) then they are skipped.

; USER button emulation by keybaord. Usually it's reset button.
; 0 - lctrl+lalt+ralt (lctrl+lgui+rgui on keyrah)
; 1 - lctrl+lgui+rgui
; 2 - lctrl+lalt+del
; 3 - same as 0 (lctrl+lalt+ralt on keyrah)

; !!!!
; Attention: if video_mode is not set in INI, then MiSTer will try to detect
; native mode of display and use it instead.
; Additionally, if dvi_mode is not set (only if video_mode is not set),
; then MiSTer will try to detect if display is DVI.
; !!!!

; set to 1 for DVI mode. Audio won't be transmitted through HDMI in DVI mode.

; flags - cvt=CVT timing, cvtrb=CVT-RB timing (default)

; set to 1-10 (seconds) to display video info on startup/change

; Set to 1 for automatic HDMI VSync rate adjust to match original VSync.
; Set to 2 for low latency mode (single buffer).
; This option makes video butter smooth like on original emulated system.
; Adjusting is done by changing pixel clock. Not every display supports variable pixel clock.
; For proper adjusting and to reduce possible out of range pixel clock, use 60Hz HDMI video
; modes as a base even for 50Hz systems.

; If you monitor doesn't support either very low (NTSC monitors may not support PAL) or
; very high (PAL monitors may not support NTSC) then you can set refresh_min and/or refresh_max
; parameters, so vsync_adjust won't be applied for refreshes outside specified.
; These parameters are valid only when vsync_adjust is non-zero.

; These parameters have the same format as video_mode.
; You need to supply both PAL and NTSC modes if you want vsync_adjust to switch between
; predefined modes as a base. This will reduce the range of pixel clock.

; Provided below are parameters for HDMI color controls.
; The defaults that are set below will result in an unaltered image.
; Brightness, contrast and saturation all can be set to 0 - 100.
; Hue can be set to 0 - 360, observing the HSL color representation.
; Each of 6 (mandatory) values in gain/offset can be set to -2 - 2.
; These 6 values represent gain and offset in order: Rg,Ro,Gg,Go,Bg,Bo
; Example 1: Inverted colors, hue shifted 180 degrees:
; video_hue= 180
; video_gain_offset= -1, 1, -1, 1, -1, 1
; Example 2: Slightly desaturated, warm display
; video_saturation= 80
; video_gain_offset= 1.5, -0.1, 1.3, -0.15, 0.9, 0.05

; 1-10 (seconds) to display controller's button map upon first time key press
; 0 - disable

; JammaSD/J-PAC/I-PAC keys to joysticks translation
; You have to provide correct VID and PID of your input device
; Examples: Legacy J-PAC with Mini-USB or USB capable I-PAC with PS/2 connectors VID=0xD209/PID=0x0301
; USB Capable J-PAC with only PS/2 connectors VID=0x04B4/PID=0x0101
; JammaSD: VID=0x04D8/PID=0xF3AD

; Disable merging input devices. Use if only player 1 works.
; Leave no_merge_pid empty to apply this to all devices with the same VID.

; Same as above but can add multiple devices (one entry per VIDPID). Format is VIDPID in hex number

; Permanently assign specific controller to specific player.
; Normally you don't need to use this option, but if you use arcade cabinet with integrated controllers then
; you may want to use it for specific player regardless which controller is used first.
; To assign it, you need to provide unique part of this controller ID.
; In USB debug log you may see list of input devices right after core has been loaded.
; For example:
; opened 0( 0): /dev/input/event8 (1915:0040) 0 "7c:10:c9:15:22:33/df:47:3a:12:44:55" "Flydigi APEX2"
; ...
; opened 7( 7): /dev/input/event3 (1997:2535) 0 "usb-ffb40000.usb-1.6/input0" " mini keyboard"
; opened 9( 9): /dev/input/event0 (046d:4024) 0 "usb-ffb40000.usb-1.2/input2:1/4024-19-a2-39-0a" "Logitech K400"
; following part is unique identifier in system ^^^^^^^^^^^^^^^^^^^^^^^^^^^
; So you need to provide part of this string identifying exactly this device. Don't include inputX part as it may change after reboot.
; Wireless devices usually have format MAC/MAC, wired devices use usb-... format.
; Example of such unique part of strings:
;player_1_controller=usb-1.2/ ;include / at the end so it won't match with something like usb-1.2.3

; Speeds in sniper/non-sniper modes of mouse emulation by joystick
; 0 - (default) - faster move in non-sniper mode, slower move in sniper mode.
; 1 - movement speeds are swapped.

; Uncomment following option if you don't want to see a second line for long file names in listing.

; 0 - disable MiSTer logo in Menu core

; Custom shared folder for core supporting this feature (currently minimig and ao486 only)
; Can be relative to core's home dir or absolute path.
; Path must exist before core start to use it, or it will fail.
; Make sure USB device is mounted before use shared folder on USB!

; Custom aspect ratio

; use specific (VID/PID) mouse X movement as a spinner and paddle. Use VID=0xFFFF/PID=0xFFFF to use all mice as spinners.

; spinner_throttle with base value 100 gives one spinner step per one tick. Higher value makes spinner slower.
; Lower than 100 makes spinner faster. Negative value gives opposite direction.

; 0 - X axis, 1 - Y axis.

; Default filters for video scaler. Paths must be relative to "Filters" folder without leading slash.
;vfilter_default=LCD Effects/LCD_Effect_07.txt

; Default filters for audio. Paths must be relative to "Filters_audio" folder without leading slash.

; Defines internal joypad mapping from virtual SNES mapping in main to core mapping
; Set to 0 for name mapping (jn) (e.g. A button in SNES core = A button on controller regardless of position on pad)
; Set to 1 for positional mapping (jp) (e.g. A button in SNES core = East button on controller regardless of button name)

; Write out file name under the cursor in browser for external integration
; External application or script may parse the info and do some additional actions and/or send info to 3rd party server.
; Warning: it may slowdown the system or add lag while browsing the files in OSD depending on external app/script.

; Automatically disconnect (and shutdown) Bluetooth input device if not use specified amount of time.
; Some controllers have no automatic shutdown built in and will keep connection till battery dry out.
; 0 - don't disconnect automatically, otherwise it's amount of minutes.

; Reset Bluetooth dongle before pair dialog.
; Some dongles may have problem to pair if not explicitly reset.
; Some dongles (mostly CSR) have problem to pair with BLE if not reset in advance.
; Consequence of reset: some input devices get shutdown after reset.

;default Shadow Mask

;default shadow mask mode:
; 0 - none, 1 - 1x, 2 - 2x, 3 - 1x Rotated, 4 - 2x Rotated

; Wait for specific mount before start the core.
; Attention: waiting is performing BEFORE core start, so no message will be displayed on screen!
; It's useful for debugging when core is loaded from USB blaster and games folder is on USB or Network drive.
; This option cannot be used when defmra in CONFSTR is used (i.e. if arcade rbf is loaded directly not through MRA).
; This option is ignored for Menu core.

; Overrides for video mode
; When the core's video mode matches the parameters in the section header, any options in the section override options from MiSTer and core sections.
; Refresh rate in header is optional and, if present, must match exactly the output from video_info or the logs. For example, if it says "60.0Hz", the header needs to be "@60.0" to match.
; When the core changes video mode, MiSTer will first look for a matching WIDTHxHEIGHT@VREFRESH section.
; If no match is found, it will fall back to a matching WIDTHxHEIGHT section with no refresh rate.
; If there is still no match, MiSTer/core options will be used without overrides.
; [video=640x400]
; ...
; [video=640x400@70.1]
; ...

; Wheel centering force 0-100. Default is 50.

; Wheel steering angle range. Supported ranges depends on specific wheel model
; If not set then default (depending on driver) range is used

; Enable game mode on HDMI output. It may give you better optimization on some displays, but also
; can give worse result on others. Default is 0 (non-game).

; Variable Refresh Rate control
; 0 - Do not enable VRR (send no VRR control frames)
; 1 - Auto Detect VRR from display EDID.
; 2 - Force Enable Freesync
; 3 - Force Enable Vesa HDMI Forum VRR
; Minimum framerate in VRR mode.
; Maximum framerate in VRR mode (currently only used in Freesync mode).
; VESA VRR base framerate. Normally set to the current video mode's output framerate

; disable autofire if for some reason it's not required and accidentally triggered


As you can see, I have tried to set custom configuration for the Odyssey2 to see if it will let it sync with my tv, but so far no luck.

Has anyone else had this kind of issue with the Odyssey2 core?
Or does anyone have any ideas how I could fix it, like maybe a core config file that works for someone...
I am currently using my mister on a LG C9 OLED.

Thank you!

I have this issue with a lot of cores, some of them I’ve been able to see just enough as it is scrolling to change the video options to something that works. I cant recall if that is something that would work with the o2.

Is there supposed to be a boot.rom in the odyssey2 games folder?

Mine is empty, wondering if the missing bios is the issue.
I have tried so many video option now, cant get this one to work at all.

Every single other console core works perfectly. :(

It doesn't require a bios or a boot.rom.
If you have a keyboard attached to mister, after loading core, wait about 30 seconds to a min, then hit the space bar.
Eventually pong will start playing and you may possibly hear sound if your TV hasn't cut out the signal completely. This of course is only to indicate the core is running.
Another thing you may try, is setting the default video_mode to 8 from 14, in the event there is an issue switching from one mode to the other when loading the core.
I don't have access to any monitor/tv that supports video mode 14 so I can't test it myself.

Well never mind my last post...I do have a monitor that supports that resolution (funny enough it's the Odyssey Ark) so I managed to try it out.
Change the Odyssey2 section to this:

Code: Select all


edit: Added a pal mode line, in case the core wants to switch to a pal frequency.
