You've spent years telling us again and again about your ambitious Jaguar projects and how advanced they would be (here's an example from less than a day ago). Yet you have released absolutely nothing, not even an "Hello world" project.

Unfortunately, I think you have to be the copyright holder for your report to be considered.

You should report him. If TXG/MNX does has well, that's already two strikes out of three.

Don't waste your time. philipj is that friend that goes on and on about how he's gonna be a rock star when he grows up. But you've never heard him playing anything, because he always has an excuse: his amp is broken, or he hurt his hand while playing tennis, or his guitar is out of tune, or...

Super Burnout is worth checking out as well.

Looks good to me.

Wow, $99 for Tempest 2000?! I knew Jaguar prices went up, but I didn't know they went up that much.

Unfortunately, that won't stop some people from making pirate copies, and other people from buying them. @str0m said above that the guy was selling Tempest 2000 repros, and you can't really argue that Tempest 2000 is hard-to-find or expensive.

Definitely not a legit copy. I've forwarded the link to the author of the port.

Ah, OK. It's fine then

There's something I hadn't noticed before: I wonder if there's a risk that those thin traces could be damaged by repeated insertions, or shorted together by the cartridge connector's contacts. Just to be sure, I'd recommend moving them of that area, or maybe applying a bit of kapton tape to protect them if it's too late to change the PCB layout.

Availability of components from this kind of brokers should be taken with a (big) grain of salt. A significant percentage of them don't actually have the stock they claim to have; when you place an order, they try to buy the components from someone else (and may not succeed). You may also get junk: chips crudely desoldered from circuit boards, defective or lower-grade chips, or even unrelated chips repainted to make them look like the ones you're looking for.

The rB+ toolchain uses a BASIC-to-C converter, so internally it relies on a C compiler and RAPTOR. You could take it apart and use that as a basis.

As if the JagCD wasn't an instable enough device as it is...

Which firmware version did you install? Any new features or bug fixes?

I have opened a few different Jaguars and don't remember ever seeing the layout on the right, even on M models.

Usually, PCB manufacturers who do electrical testing mention it explicitly. Some of them let you choose whether you want it or not, to lower the price. If they don't say anything about it and the price is cheap, I'd assume they don't do any testing.

Yeah, but you say the same about Bubsy 😛

Does your PCB manufacturer offers electrical testing? If not, a possible cause is a defective PCB with an intermittent short between close pads or inner layers.

Once again, if you have unpopulated prototype PCBs left, I may be interested

If by "someone" you mean the team that released the Jaguar version of Another World, contacting them directly would be more efficient than posting in a thread they may not read. If not... asking for dumps of homebrew games is not right, and offering money for it is even worse.

Yes, 16 1N4148 diodes. I don't understand what you mean. Anyways, the circuit diagram in the Jaguar FAQ is correct. Just use it as is.

Why would you need a physical cartridge to go with a Jaguar GD? 😕

I don't know if anyone made a video of it, but you can download it here:

Jagmania is by @Matthias (Matthias Domin). Someone should let him know.
