Megadrive Interlaced mode: which games?

[McValdemar]

Hi everyone, I was curious to see how a game looks like when MegaDrive is using the interlaced modes such as 320×448.

I expect 30FPS, correct?
Is there any game that uses this mode during all the game?

The only one I know is Sonic 2 but only in the split screen mode...
Any other title?

Combat Cars also uses it in split-screen mode:

The Censor C64 Picture Demo also uses it.

Sonic 2 2-player does not look like 30 fps to me, it runs just as smoothly as 1p mode.

The interlaced modes run 60fps, but interlaced. Which some people translate to 30fps but this is not correct - it runs 60fps but only updates half the lines on the screen per frame.

Exactly.
Initially I tought that the interlaced mode was working like on C64 where you gain a fake higher resolution with flickering. Not the best but actually you have this perception of hi-res.

On MD I see (from emulators) that actually works in the way that you have the larger image in the buffer but is rendered every other line with no higher res perception to the eye. So, seems very fitting the usage is done on Solnic 2 where you don't change tiles but you can squeeze in one screen what would require two screens.

At least from the emulator.

Are there any tech demos or homebrews that use interlaced mode for high res video or gameplay? It would be cool to see an MD game running in native 320x448.

It's not interesting for homebrew because interlaced sucks on modern TVs.

[McValdemar]

This was my idea but I see it works differently. You don't have a flickering higher resolution as happens for C64.

[roce]

You do have a fake, flickered higher resolution. That's the very definition of interlaced. Perhaps C64's is somehow worse, or not handled well by your TV.
