I'm actually surprised the NES gun works..
The light guns are IR right? Point it at your phone camera and see if there's a flash of light when you press the trigger. Might be a problem with that part
Different light gun technology.
The Sega Master System gun is scanline based, locked to a 15KHz signal (PAL or NTSC works, but it must be 15KHz horizontal scan rate, which is your 240p-288p type range). Your 2x scale breaks how it works, as it's trying to see a horizontally drawn line at a given scanline point at a instant snapshot line up with where your gun is pointing. This is the same way Guncon 1 and 2 guns (PS1 and PS2) work, the Sega (Megadrive) Menacer, Sega Saturn light guns, and SNES Super Scope. These all *MUST* be used on 15KHz scanline based displays (i.e.: 15KHz / SD CRTs only. Not even a 31KHz VGA CRT will work).
The Dreamcast light guns are a bit different, and can handle dual 15KHz (SD) and 31KHz (VGA) scan rates. Non-CRT displays won't work, however.
The NES light gun is utterly trivial by comparison. It inserts a single black frame with a white square on screen, and if the gun's "camera" sees it's pointed at white instead of black, it registers. Any scaling and even emulation works as long as there's no lag. People have had it working with a low lag LCD and RetroArch's "run-ahead" emulation.
Not for NES, no.
Wii and PS3 light guns use IR. So do recent remake hardware like Act Labs guns, Aim-Trak, etc.
I didn't realise how much I didn't know about light guns. Great post.
Great post indeed, thanks elvis
I can live without Rambo III fortunately but I'll hang on to the gun for old times sake.
RetroRGB has done a nice "beginners" video up for the RAD2X - a device designed for 100% plug and play from retro console to new flatscreen HDMI TV or monitor without any nerdy crap to worry about.
This video focuses on the SEGA MegaDrive / Genesis (which should also work on the SEGA Master System first model), as well as variants and addons.
Voultar was talking up this project on the retrorgb discord https://github.com/ramapcsx2/gbs-control
I've just ordered the parts needed from china - I'll let everyone know how well it works early next year when the bits arrive.
I've been following this on the shmups.com forums for a while. Looks pretty interesting. Keen to hear how it turns out for you.
anyone out there tried this with a dc pound cable?
sigh. I feel this is the kind of thing that shouldn't be documented on Facebook. I've been hunting for that post but unfortunately my social media skills are not great.
DC Junkyard is your numero uno DC FB source. It's an offshoot of their website.
link to post because i should have added it before (it is a group, so you'd need to join first).
I bit the bullet today and ordered a Chinese knockoff OSSC from AliExpress. $175Ausd delivered, lets see what shows up.
I'm not particularly interested in playing on an LCD but I am sick of having issues with my capture card being unhappy with various 240p signals so hoping I can upscale to something my capture card will 100% be happy with.
When I get it I'll post up some sample footage so we can see how it looks.
My RAD2X arrived on Friday and I've had some short playtime with my RGB-modded N64 and SNES. The video quality is simply awesome, and frankly it's amazing the adapter costs under $100. It gives my UltraHDMI-modded N64 a run for its money.
Composite video quality is pretty bad but that isn't the device's fault; seeing pixel-perfect dot crawl just isn't pretty. But given the price even if you only had a composite video console I would still recommend getting a RAD2X just to fix 240p handling and composite video input lag.
I've got an RGB modded N64 and currently nothing to plug it into, so both of these posts are of interest. I want scanlines, which unfortunately rules out the otherwise awesome looking RAD2X. So I'm pretty keen to hear how the AliExpress OSSC goes.
Couldn't you just slap a scanline generator inline? I use an SLG3000 which is VGA, but I know there are HDMI options out there.
Interesting thought, that's something I hadn't considered. I'd prefer to do everything in one widget, but it warrants a little homework at least.
Yes the chain of gadgets can get out of hand
how does this stand up against the retrovision HD component cables?
I can’t really compare them because I don’t use them for the same thing. I don’t have a scaler, the HD Retrovision cables are just plugged into a PVM. And the RAD2X into a 50” LCD.
All I can say is they both look really, really awesome.
So my Chinese OSSC arrived. This is what you get:
The power supply was worthless, the adapter supplied isn't for Australian outlets.
The build quality of the unit itself seems very good, it's all machine soldered and very neat. Everything seems to work though I've only had an hour or so to set it up. The firmware on it is 0.84, I haven't attempted to upgrade it yet.
I am not going to get a chance to play for a few days but here is some test footage from a Sega 16 Arcade PCB running from a Minigun supergun into the OSSC at 4x:
Seems to be doing it's job well!
