Software Test Patterns

[retrorgb]

Does anyone know if some kind of test software exists for the Jaguar?  If not, would any of the awesome dev's here be able to help?  The tools we're most looking for are (in this order):

 

- All white screen at 100% brightness.

 

- 100% color bar screen - This would accomplish the exact same thing as all white screen when testing voltage, but could also help with color checking.

 

- Sound test where you can select Left, Right and Center to test the audio output.

 

In a perfect world, we'd have the 240p Test Suite, as well as MDFourier ported to every console in existence, but that's a lot of work.  I was hoping someone hear knew of basic tools like they that already existed...or maybe someone would be gracious enough to just write a single ROM with either the 100% white screen, or 100% color bars.  I'll be happy to host the file if needed and would gladly write a post to promote it.

 

Thanks in advance for any help anyone can provide.

Looks like the very beginning alpha work is starting on the Jag 240p Test Suite.  Maybe if you're a dev with Jag knowledge, you can join their discord?  These tools help both software and hardware developers.

This is interesting. Would you provide additional information? I see two older threads from a couple of years back but nothing recent. Which Discord are you referring to?

It's the discord associated with this group.  I think the link to join is in there:  https://junkerhq.net/240p/

There's a test cartridge made by Atari that may be useful (it includes color bars and audio tests). The ROM and the documentation is in this thread:

Here's how the tests look like:

It took some time, but this early version of the 240p Test Suite for the Jaguar should be helpful.
