Many of those "increased capacity" cards just gain extra space via compression, without actually having more space. So if the cards firmware goes corrupt, most likely so will the entire card. Some of them are also able to lock out the region.
I don't know if that card does any of the above though. Could you open it up and post some pictures of the board? Preferably with any text on the chips readable.

Have you tried cleaning the connector? I've got a virtua stick once that was listed as junk, but it only had contact problems and no other problems.

Have you tried swapping out the power supply? Might be what caused the problem. I can try that. Has this been the cause of the issue in your experience Zyrobs? Would the PSU cause the system to still function? (disc still loading/reading but visual and sound output gone?) Cheers The disc system is entirely independent and will keep working even if the main system locks up. Though at that point it is only doing its basic tasks (like keeping a disc spinning in anticipation of later reads, or spinning up on reset, stuff like that). Power Supply is one part which does have known issues and known dodgy components, so it is a good start for looking for errors. Which reminds me that I should get some replacement TOP PWM switches.

The Trurip dumps work most of the time, except for some that have parsing errors in the subcode (which may or may not get fixed with a firmware update).
For homebrew, just mount them to a virtual drive and rip a CDI from the virtual drive with Discjuggler using the appropriate options.

Yeah, I got mine way back in November.

Good luck trying to find any broken titles, so far there are only 3 known. IIRC Nights uses XA tracks instead of the usual data+audio. Games using mode 2 tracks work fine on Rhea, including Nights, as well as the Mogitate Sega Saturn discs, including MPEG card support (they use double MPEG streams).

if it works for booting up, it it works for playing games, it it works for memory management... ....why doesn't it work for 4MB RAM games? =P. Really want to try Street Fighter Zero 3! Could be an early cart, those were 1mb only. Open it up and check the memory modules (or post a picture of the board).

Clean the cart before you go blaming the cart slot.

Okay, I have one of those. The component in question is a TOP202YAI PWM switch, not a voltage regulator. They are known to be quite bothersome, causing problems often in 220V Saturn power supplies. The modern replacement part is the TOP224Y.

polygon problems mean that something around the VDP1 is not right.
Sound hissing after 10 minutes can be a lot of things, such as power supply, bad caps, or even the modchip causing some interference.

Could you please post a picture where the entire power supply is visible, so we can know what type of power supply it is? Otherwise no one will be able to tell you what parts you'll need.

Actually last time I was at home with it, I took these pictures incase it would be of use. This is the cable that came with my Sega Rally/SWWS97 console bundle That's the highest quality SCART cable they ever officially released for the Saturn, as far as I know. It has individual shielding on the audio lines, which almost completely eliminates audio noise (you have to really turn up volume to hear any). And yeah, it is definitely RGB. Only problem they have is that due to their age, a lot of them came loose on the Saturn a/v end, so you have tons of issues like one colour or sound channel not always connecting depending on the angle the connector sits at. I had to buy a couple of spare plugs to fix up such cables - using one myself as well.

All the pins for audio and video are there, the missing ones are for things which are not used by the cable. If you open up your cable that has all the pins filled out, you'll see that half of them aren't connected.
It's odd that you only got black and white picture with that cable. I have a couple of original cables (both the early and the later types) and they all get perfect RGB picture on all the PAL Saturns I tried them with. So it is probably a TV issue. Maybe because some of the ground pins are not connected on the official cables.
I've heard that the fact that the Saturns came with SCART leads led to a huge uproar back in the day, and many places ended up selling RF connectors because TVs didn't have SCART connectors on them. Possibly they also had problems with black and white picture like that.

Are you sure your PAL Saturn came with an RGB Scart? As far as I knew UK Saturns just came with normal SCART leads which were not RGB. I've owned 2 UK Saturns and non of them came with RGB Scarts. You're issues in that video look similar to mine only my main problem was everything was displayed in black and white. I had to go elsewhere to buy a TRUE RGB Scart and the problem stopped. The Scart leads that came with UK Saturns were definitely RGB.
