Unlock the analog potential of MiSTer FPGA with IO Analog Pro! Boasting accurate analog video, crystal clear analog audio, soft power toggle, and compatibility with the incredible MiSTer passively cooled aluminum armor case. Existing case owners can purchase a replacement rear panel.

Features

  • Reference-quality analog video and audio via Sega Saturn AV port
    • 99% accurate to specifications
    • RGBs
    • YPbPr** with improved sync levels and correct 700mV Luma
    • S-Video** (native YC core support)
    • Composite Video** (native YC core support)
    • DIPs to enable 24-bit video depth (Enabled by default)
    • Hi-Fi analog audio
  • Mini TOSLINK digital audio
  • USB-C power for use with soft power toggle button (experimental). Might need an extra tap every once in a while :). USB C expects 5V 2-3A. It works with USB-A and USB-C cable types. Check your power supply if you’re not sure. DC power jumper is used to route power to the USB hub from the DE10-nano.
  • ADC-In (integrated into the rear 3.5mm port)
  • User port for SNAC and mt32-pi
  • Simultaneous analog and HDMI output
  • Single SDRAM support
    • Looking for dual SDRAM IO board, and don't mind giving up simultaneous HDMI and analog video? Check out my upcoming IO Direct! No cores currently require dual SDRAM. Jaguar (alpha), Saturn (beta), and Williams Y/Z unit arcade machines (upcoming) all need or benefit dual SDRAM.

** Use alternate INI files to switch between analog video formats (MiSTer_xxxx.ini)

Video measurements

Note: All non-MiSTer Addons measurements were taken by Kuro Houou.

DE10-nano Configuration

To choose between Mini TOSLINK digital audio, and the hifi analog audio DAC, toggle the DE10-nano's switch 0 [SW0]. Choose the position closest to the PCB edge for digital audio, and the position closest to the center of the PCB for analog audio.

The DE10-nano should be configured for different IO boards as follows:

Build SW3 SW2 SW1 SW0
IO Analog Pro (Analog Audio) OFF OFF OFF ON
IO Analog Pro (SPDIF) OFF OFF OFF OFF


MiSTer.ini Settings

This IO board can output several different analog video formats, but not all simultaneously. Use the table or text blocks below to configure the MiSTer.ini file on your micro SD card. For testing purposes, I have 4 separate .ini files on a single card that I can easily switch between using controller button combos. Most users will probably want to modify their single MiSTer.ini file according to their desired video format.

240p RGBs

[MiSTer]
forced_scandoubler=0 ; set to 1 to run scandoubler on VGA output always (depends on core).
vga_mode=rgb ; supported modes: rgb, ypbpr, svideo, cvbs. rgb is default.
composite_sync=1 ; set to 1 for composite sync on HSync signal of VGA output.
vga_sog=0 ; 1 - enable sync on green (needs analog I/O board v6.0 or newer).

480p RGBs (requires Saturn to VGA and a monitor that supports composite sync)

[MiSTer]
forced_scandoubler=1 ; set to 1 to run scandoubler on VGA output always (depends on core).
vga_mode=rgb ; supported modes: rgb, ypbpr, svideo, cvbs. rgb is default.
composite_sync=1 ; set to 1 for composite sync on HSync signal of VGA output.
vga_sog=0 ; 1 - enable sync on green (needs analog I/O board v6.0 or newer).

240p YPbPr/Component video

[MiSTer]
forced_scandoubler=0 ; set to 1 to run scandoubler on VGA output always (depends on core).
vga_mode=ypbpr ; supported modes: rgb, ypbpr, svideo, cvbs. rgb is default.
vga_sog=1 ; 1 - enable sync on green (needs analog I/O board v6.0 or newer).

240p S-Video + Composite Video

[MiSTer]
forced_scandoubler=0 ; set to 1 to run scandoubler on VGA output always (depends on core).
vga_mode=svideo ; supported modes: rgb, ypbpr, svideo, cvbs. rgb is default.
ntsc_mode=0 ; Only for S-Video and CVBS vga_mode. 0 - normal NTSC, 1 - PAL-60, 2 - PAL-M.
composite_sync=1 ; set to 1 for composite sync on HSync signal of VGA output.
vga_sog=0 ; 1 - enable sync on green (needs analog I/O board v6.0 or newer).

    The best analog solution for mister!

    I've used every method of getting analog from my DE-10 Nano to my CRT, from the old analog IO board to HDMI solutions but it never looked or sounded right and was a mess of cables and adapters. Not only does this look LITERALLY superior to my original hardware, but it manages to do it with only two cables. USB-C is so convenient for power and the saturn out port for audio and video is so much more robust and my mister no longer tips over from the weight. if you game primarily on CRT with mister, don't hesitate. buy this and enjoy the best possible method out there!

    Worth the wait!

    Analog IO Pro is exactly what I’ve been hoping to have for years. Excellent reference quality output, support for 24bit, fixed issues with audio quality, the list goes on. The amount of extra stuff I could ditch that is consolidated into the board is great and the ability to easily switch to different output types is a fun way to explore different looks for games of this era.

    Upgraded from Digital I/O Board

    I go back and forth using my MiSTer in a DV->VGA->Component to my CRT setting to a DV->RetroTink4K, and having to reach behind to swap cables has been a drag. With this, I'm able to have my CRT plugged in with a single cable without all the extra USB power and leave the HDMI plugged into the Tink with no issue. Color and sound are perfect. I also feel like I get a picture faster after power on and resetting. You should get one if you have any thoughts of having a similar dual setup.

    MA kills it again

    I've been exclusively using Mister Addons since building my first unit in 2020, and every component has operated flawlessly which keeps me coming back. I keep up with the tech, and the Analog Pro is probably the best put together analog video solution for the Mister on paper, and as usual for MA in practice it does not disappoint.

    Outstanding product.

    It really doesn’t get any better than this if you want the best analog video and audio for your crt and still having the convenience of hdmi into a capture card. I absolutely love it. Works perfectly with either the Saturn premium universal cable or Saturn scart cable from this shop. Really cleaned up my streaming setup. Fast shipping as always too. Thanks.
