DCHDMI Settings Summary
Open up the OSD by holding down (Left Trigger + Right Trigger + X + A + Start)
**If you have a resolution setup that is not supported by the TV, use this command to get back into VGA mode:**
**(Left Trigger + Right Trigger + Y + B + Start)**
- Select your desired output resolution:
- 1080p will have black borders around the image. This allows for pixel perfect presentation.
- 960p may not work on all TV's. If you get a black screen after switching resolutions wait 15 seconds for resolution to switch back.
- 480p mode will show a squashed image on any standard Dreamcast game. This option was kept as some homebrew use all 720 horizontal pixels.
- VGA mode will display the 640x480 resolution in the correct aspect ratio on your HDMI TV
- This sub section allows you to add scanlines to the image. These settings are self explanatory.
Video Mode Settings
- The Dreamcast can internally render images at 240p/480i OR 480p. The DCHDMI is able to tell the Dreamcast which method to use.
- Force VGA mode simulates inserting a VGA box. This will make the Dreamcast internally render games at 480p. Make sure your game supports 480p when using this option.
- Cable Detect by default puts the Dreamcast in 240p/480i mode. You can insert an RGB Scart cable / composite cable. If you insert a VGA box the Dreamcast will switch to 480p
- Switch Trick VGA is option for a select few games that will not start in 480p mode. But can work after switching to 480p once the game has started.
- You can update your DCHMI easily via WiFi.
- The update procedure is simple and goes in this order: Check -> Download -> Flash -> Reset
- Make sure to NOT turn off your system during a firmware update.
- During the start of the flash procedure the screen will not change for 5-10 seconds. This is normal.
- This allows you to easily setup your SSID and password on your WiFi network.
- If you enter incorrect information or the WiFi is down, the OSD will not be available for 10-15 seconds after startup.
- There is one optional output on the DCHDMI. This can control the onboard LED, reset the USB-GDROM back to game selection or simulate GDEMU button press.
- The GDEMU always resets back to folder 01 during reset, while USB-GDROM will reload the previously loaded game during the Dreamcast reset.
- These options are 100% optional. The default setting is LED.
Advanced Connection to the ESP
- If you want to mess around more, you can access the ESP module directly with a web browser.
- If the ESP is not connected to a WiFi network, it will create an Access Point in which you can connect to:
- If the WiFi is setup already, you need to lookup the ESP IP address in your router OR if you have mDNS support goto this url: dc-firmware-manager.local
- After connecting you will be guided through a setup.
- Once connected and setup you can type "help" for a list of commands
