    Attempting to hook up PC to Dynamo HS-27 help!

    Are you saying it's so far over to the right that you can't center it using the H pos and / or H hold pots? What happens if you try and center it? (I.e. how much of a gap is left if you max out the available adjustment on the H pos pot?). It's not unusual for the image to be shifted a little...

    Testing BNC and VGA cable voltage and resistance

    I thought about that but everyone keeps telling me how terrible they are. I'm not really sure how many have actually used them though. The rgb image on one of those curved sharp TVs looks about the same as on a K7000 though. So, if I use them for one game (I.e. Not in a mame cab with constant...

    Testing BNC and VGA cable voltage and resistance

    Yup. You can't beat a decade appropriate curved slot mask tube for standard res arcade games. I just wish I could still buy them these days. The supply of curved standard res arcade monitors has completely dried up near me. I was considering learning how to RGB mod one of those old curved...

    Attempting to hook up PC to Dynamo HS-27 help!

    If you went through the CRTemu installation properly and then selected 640x480@60i for your Windows desktop res, you may just need to adjust the V hold and / or H hold pot to stop the image rolling. You should be using the Arcade OSD to set the Windows desktop resolution. In there you'll be...

    Testing BNC and VGA cable voltage and resistance

    Yeah the control draw is cool. In terms of technical excellence and overall image quality for old games I rate the Ikegami TM line above all others. They have fantastic contrast, geometry and convergence. I've been through a lot of monitors including various Sony PVM and BVMs. My Ikegami...

    Neo Geo MVS, incompatible with SuzoHapp CGA LCD?

    That's awesome if it has different scaling algorithms that are optimized for each game. I don't know of any other options that are so versatile. I love that people are doing diy and open source scalers using commonly available and inexpensive hardware these days. Decent scalers have...

    Attempting to hook up PC to Dynamo HS-27 help!

    That would certainly make the process more annoying. I'd probably still want to do it anyway, even if it meant using splitters, switchers and maybe one of those 8" crt monitors on the side to see what I'm doing while the main monitor is off. I guess it depends how much the individual cares...

    Attempting to hook up PC to Dynamo HS-27 help!

    Crtemu drivers and groovymame has a setting for both dual sync as well as tri-sync and 15khz only monitors. If your monitor can do both 15khz and 24khz it's worth using the dual sync setting. The whole point of groovymame is to play all games in the correct res and refresh rate. While there...

    How to simulate a button press using a microcontroller?

    If you're trying to increase output voltage then you use a boost or step-up converter. If you're trying to reduce voltage you'd use resistors or pots. A button press is just applying or disconnecting voltage (I.e. closing or opening a circuit). One of the easiest ways to do this is with relays...

    Testing BNC and VGA cable voltage and resistance

    Rgb is just a color space. If a TV can't handle 57hz or 54hz games etc then it doesn't matter if you use rgb, component or composite video, it still won't work. Similarly, using RGB won't prevent an overload if you connect a PCB directly to a TV without going through a supergun (or cable with...

    PlayStation 2 OPL+SMB

    I thought the bandwidth would be an issue. I remember being surprised when I first installed a hard drive that it didn't change the loading times that much compared to using CDs and DVDs. It wasn't like playing PC games off a hard drive. It was only a little faster. I didn't know if the slim...

    Testing BNC and VGA cable voltage and resistance

    If you're using a supergun you shouldn't have to worry about voltage as that is one of their primary functions. Plus, pro monitors often have over-load protection or warnings built in. If I feed my Ikegami an overly bright image the warning light comes on to remind me to turn down the...

    Testing BNC and VGA cable voltage and resistance

    That's the nature of analog rgb signals. They aren't all the same. Unless there is a specific problem you are trying to diagnose, don't worry about it. I've had no issues just using an analog volt meter for testing rgb voltage. Just put a white image on-screen (if one is available on a CRT...

    Neo Geo MVS, incompatible with SuzoHapp CGA LCD?

    Luckily it's only temporary and hopefully it will just make you appreciate your crt even more when it's fixed. Arcade scaling is a tricky issue with there being so many obscure resolutions. An algorithm that looks OK upscaling 240p to 960p for 1080p and 4k monitors might not be so great for...

    Lightgun to USB

    Yes, Sega IR guns are the ones with the 10 led boards around the screen. Sega used them in every arcade shooter since House of the Dead 2. I got the info from Twistedsymphony's thread on this site. Just search for "Sega type 2 guns" and you'll find it. He did all the initial work and an...

    PlayStation 2 OPL+SMB

    How much loading time does it save vs using an SSD hard drive via the network port (on the launch model)? I understand that owners of the slim mode' have to remove the DVD drive and use that port due to the slimmed down hardware design. I didn't know it was faster. Is there an additional...

    What advantage does the raspberry pi set-up offer over just using a regular Sata hard drive (with a sata network adapter)? I thought that's what every did these days. Does the Pi reduce loading times further?

    Neo Geo MVS, incompatible with SuzoHapp CGA LCD?

    That's a strange approach on their part (I mean Happ). Stretching an image to fill the screen on an LCD is just more scaling. It's not like the analog stretch on a CRT where you change the shape and size without changing the resolution. Even the best scaler in the world wouldn't help if you...

    Neo Geo MVS, incompatible with SuzoHapp CGA LCD?

    Does that monitor have V-size and H-size controls to allow for games that used non-square pixels? I can't fully see in the photo but it looks like the wavy lines at the top are the ones that are meant to be there. They'd just not be visible on a CRT as they'd be clipped by over-scan. I assume...

    Anyone here seen Time Crisis 3 working with CCD gun?

    Most of us are in the same boat. If money was no object then there would be no PCBs left on ebay. All you can do is keep an eye out for a deal on what you want and prioritize. Luckily all the multi game options and cracked PC based arcades is making it easier as you can just buy each bit of...
