I love the Mega Drive V.R.

the SVPs ran too hard for the process used so they quickly self-destructed. Sega advised store owners to not run Virtua Racing in kiosks for extended periods of time to prevent malfunctions from happening.

Is this a recent discovery?

If it's not, I'm shocked this is the first I'm hearing of it, figured it'd be the subject of a bunch of youtube vids.

AFAIK the SVP was like 25Mhz which was probably too much for it. I don't know what specific node size they used but clearly too much for the speed they were running them at. They might have fixed it with a die shrink but...

>faulty design and quickly self-destruct
Sega didn’t use a good enough heat sink so the chips fried and failed, the actual design was fine, they didn’t self destruct.

That reminds me of the Capcom CPS-01-A chips which are notoriously unreliable but the later B series had a die shrink and got rid of that issue.

it's widely believed this was the issue with the first revision SNES chipset as well.

Are they really that prone to failure? Has anyone had their Virtua Racing cart die suddenly?

the tight closed up space of a cartridge shell also really wouldn't offer any room for the heat to dissipate

Ridge Racer was also horribly unreliable and it was seemingly always a GPU issue.

Never happened to me. But it could be that any carts that were going to die died long ago. However, since many working carts still exist they obviously didn't all self destruct.

There are several interviews where people from other companies (Nintendo, Namco, Capcom, etc) talk about how reckless Sega was with their money. Sega would throw big amounts money around just to match their competitors. One interview, a former Namco executive said that such big spending is not sustainable and is not financially a good idea in case something goes wrong. He was directly discussing Sega.

AFAIK people have modded these carts to put proper heat sinks in them. Yeah it was apparently a die size issue a lot like the first Famicoms that overheated.

Certainly possible, but implausible. Despite how bad the game is the sheer number of working copies in existence make it hard to believe the problem was as bad as some people make it out to be.
