Are there any DIAGNOSE cartridges / software for MSX?

I'm curious about the existence or not of test cartridges for MSX. Other systems seem to have some of those cartridges, being them products used by official repair services at the time, or fan-made diagnose programs used by users to help them detect failures in their own computers.

Does test cartridges for MSX exist?

Is there any repository with test programs ( any program, not necessary cartridges) for RAM, VDP, CPU, etc... to help diagnose problems?

It seems to me that in the repair front the MSX community is a bit behind other systems, so I would really like to know the tools we have at our disposal. Wink

Thanks theNeustro, this is just the kind of product I was thinking of. Big smile Big smile

Of course I didn't know about it, it seems a very recent project ( and I'm not as connected with the scene as I once was).

Would it have made sense if the physical release included e.g. 16kB RAM? My guess would be than if an MSX has defective RAM you would be able to still boot the machine and run the tests.

Tested version 1.2.0 and 1.2.0 upd1 - both didn't work on my Philips 8020 and Yamaha YIS-805 from Carnivore2. That is weird, because version 1.1.8 started without any issues, but the screen was somewhat corrupted. Did anyone else have this problem?

FYI: Tested version 1.2.0 on my VG-8010 and it had no screen corruption. What corruption do you see ?
