Pretty sure that Sophia 2 also allows for far easier switching between the resolutions i.e if you need to connect to different screens with different aspect ratios etc. My rev C board is fixed at a certain 4:3 resolution and would need to be returned to the guy who makes them if I needed to change its output resolution.

The GTIA chip is one of those big ones in the bottom-left of your photo. Yes you need to de-solder it and replace it with a socket first before you begin. Please see my write up at the following address which has some very useful info on the install including how to keep your rf shield and how to get audio etc...

@SainT I'd love to see a 'Delete' option to delete ROMS form the GameDrive interface on the Jag using the JagPad. My micro-SD card tends to be filled with all sorts of ROMS many of which turn out not to work when tested or they're corrupt or duplicates of other ROMS elsewhere on the SD-card. So it would be 'super convenient' to be able to delete unwanted ROMs on the Jag 'there and then', without having to remove the SD-card, put it in my laptop, find the file, delete the file etc. and without having to move the delicate micro-sd card between laptop and Jag numerous times etc. Thanks for listening :)

Great work @SainT. At this stage... is it possible for us to store our existing cart roms on the same SD card as our JCD images? i.e if we copied the JCD images to a new SD card (as advised), before copying our cart roms on to the same SD card afterwards. Or must we always keep our cart roms on a totally separate SD card to our JCD images? Also do you have a rough ETA as to when this new firmware is available to us early investors in your early JagSD cart...?

That's awesome @tjlazer many thanks, you just made my week! Have been looking for that for ages. Such a top game, takes me right back.

Hi, I'm looking for an XEX rom download of this game 'Crypts Of Terror' for the Ultimate Cart in my 800xl. Enjoyed this game a lot back in the 80s but can't find file format anywhere that's compatible with my Ultimate Cart. I've tried the conversion tools too without any joy. Supported file formats are CAR, XEX, ROM and BIN. If anyone knows of a download of any on these formats anywhere or can create one for me or advise how to create/convert one that works with the Ultimate Cart, ideally XEX format, that would be fab.

Thanks, that looks useful. I might have a go at this mod if ever I get the time. I did the 50/60hz switch mod about ten years ago which worked out great so I reckon I could manage this too. I just need to find a space on the case for the switch as I've already replaced the RF modulator with the 50/60hz switch. Have you any idea what the 'top middle' and 'bottom left' on this diagram refer too? So, should I connect my wires to the top side of those L17 and L18 components or the bottom side? Thanks.

Wow, it's certainly 'feature rich'! Did you make it as a 'one off' yourself? Do you use it? Similar outputs to my Catbox which is bulky and weighs a tonne too!

Hey folks. Does anybody know of a mod to the Jaguar which provides a separate audio output socket on the Jaguar case? The 'Retrotink 2X SCART' solution and the 'SNES2JAG + Rad2X' solutions are great if your screen/monitor has speakers or if your screen has an audio output which you can connect to speakers. However if you have a screen (like the NEC Multisync LCD 1970NXp that I have) then you get no sound whatsoever. I'm currently using an older (un-shielded) SCART cable to connect my Jag to my 'RetroTINK 2X' which provides two additional (L+R) RCA audio leads but it's not great because it's an old DIY cable which is un-shielded and so the picture is not as quite good as my standard Jag SCART cable. I would like to be able to connect by Jag to my RetroTINK 2X using my high quality standard SCART cable and then get audio separate audio socket(s) on my Jag, via a custom audio mod of some sort. Any ideas/suggestions folks?

For anyone looking to buy the 'rare as hen's teeth' RAD2X to go with their new SNES2JAG adapter, head on over to eBay and grab this one. Only 8 hours left on the auction. Good luck! https://www.ebay.co.uk/itm/274401167003

Hi @cubanismo, very interesting thread, many thanks. If only I'd had that resource when I was trying (unsuccessfully) to butcher together a similar 'direct' (Jag to NEC Multisync monitor) cable of my own. So what stage are you at with this 'direct' cable right now? Are you just trying to figure out the v-sync still? Or do you think it's fine without the v-sync and just needs housing to complete? I think you're probably mistaken about this 'direct' cable solution being a niche market. The retro gaming scene seems to have exploded in recent years so there's a lot of people looking for ways of attaching their old consoles to modern screens. That includes us Atari/Jag folks. I think this solution consisting of a second hand (readily available) 15khz monitor (I found mine a few years ago easily on Ebay for £30), plus your custom Jag-VGA cable would be a really attractive, 'clutter free' and affordable solution. Especially if your cable provides a similar quality picture to the RetroTINK line doubler adapters, and if you can produce them for a relatively low price. I would buy one of your cables even though I've just spent over £100 on a RetroTINK (which gives perfect picture). I think the big advantage your direct cable would have over any line doubler or upscaler is that it's a simple/direct cable and doesn't involve an extra adapter/box which itself requires an additional power supply. All your cable would need is a particular type of (readily available) monitor. I'd be really interested to see close up video footage of your direct cable in action. Also, yes please put me top of your list for a 'customer-ready' version. I'm happy to 'test' prototypes for you too on my NEC 1970NXp. I've had 2 kids since I last tinkered with making cables like this so I don't think I'd have time to make one myself. Love the audio-out you've added too btw.

Thanks @eightbit and apologies if I referred to the 'RetroTINK 2x Scart' as an upscaler rather than a line doubler. Having received my 'RetroTINK 2x Scart' this afternoon I can totally agree with you, the picture it amazing, the best I've ever seen from my Jag, and so much better than the 'el-cheapo' adapter I was using until now.

That's right... a 15Khz monitor SHOULD NOT need an upscaler at all, that's why I was looking at things like Catbox and Amberry adapters initially, but the picture was terrible, totally unplayable. I can only assume that my NEC Multisync monitor is not 100% 15Khz compatible, despite being included on all of the lists of 15Khz compatible monitors (e.g. http://15khz.wikidot.com/) My NEC Multisync 1970NXp works fine with the 15Khz signal from my Atari ST... but strangely it's terrible with the 15Khz video signal from my Jaguar (what is the difference though?). Does anybody else have one of the monitors from the NEC Multisync range with experiences of using it with the Jag that they can share...? Anyway, a year or so ago I finally gave up with the 15Khz approach.... and started looking at the upscaler approach. It's a shame because I'd much prefer to not have to use an upscaler at all.
