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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...
