![]() ![]() I hoped that the SoC(s) could be reconfigured to output LVDS over the same pins. Gen3+ appear to output LVDS signals directly. I've never dug in to what LVDS converter Gen2 uses, but it's likely it could be reconfigured to output a different resolution as well. I consider the sound fix soldering points to be "kind of small" these are much smaller - tiny really.) But the traces required are almost certainly too small to be reliably soldered by human hands. Gen2 boards send what appears to be an HDMI signal to an external LVDS converter IC. I've had a customer request 1280x960 on a Gen1 board (for the Gen3+ monitors), but I haven't yet taken the time to test it. It's almost certainly possible to reflash it to output a different resolution. On Gen1, the LVDS converter is a Realtek 2270-series IC. (Too time consuming for what I can reasonably charge.) (The SoC outputs VGA, which is converted to LVDS by an external IC.) I've added a VGA output to two boards for customers, but it's not something I'll do regularly. On the Gen1 boards (all the upright cabinets before Mortal Kombat and Golden Tee) it's possible to add VGA output to the board. I wasn't able to get a list of specific resolutions or ratios that were supported, but my best guess is they support at least 1280x7x1080. The later one allows a jumper to set 1 or 2-channel LVDS, and the earlier version requires different firmware for 1 or 2 channel. (I'm an english-only speaker.) Info I was able to gather: There are two versions of the board. ![]() Language ended up being a barrier to detailed technical discussions. I talked directly with a Chinese distributor (or possibly the manufacturer?) of this board about supported video formats and the option of paying for custom firmware, but they were not especially responsive. (UPDATE: His most recent The1UpWeekly episode talks about his experience with this exact issue.) I don't believe he published a video, but we discussed it a few times. I haven't personally attempted using this converter, but RetroRalph (of YouTube fame) did, unsuccessfully. I understand that this can be challenging as LVDS output is specific and may not be compatible with this converter board.ĭoes anyone have experience with this converter board? Or has anybody successfully connected the video out of A1UP PCBs to a modern monitor? Or any suggestions for how this might be possible? So far, I have tried an LVDS to HDMI converter board with no luck. This is difficult because the A1UP PCBs output LVDS. My last issue is connecting video from the PCB to my standard modern LCD monitor that has HDMI/DVI input. So far, I have connected sound and controls successfully thanks to BerryBerrySneaky and his great work on the platform. The second is that I like the implied legality that A1UP PCBs provide. The first is that I want to use my existing cabinet with its controls and display. I have a custom JAMMA cabinet with some arcade PCBs, but would like to supplement it with some small Arcade1up PCBs. It is the reverse of what most folks here are doing regarding modding where they want to hook up a Pandora/RaspberryPi to an A1UP cabinet. ![]()
