Standard keys to boot up games in 15 Khz?

[Starscream]

I've read somewhere that ESC and F1 might work for games that don't offer a switch with menus, are there possibly any more? Specifically, I'd like to know if Nemesis 90 runs in 15 Khz.

No, it doesn't.

Thanks, that's an awesome list.

It runs: press "Help" button to switch 31/15Khz. It seems every Konami game has an "hidden" key to anable 15Khz. On Gradius 2 press "F6".
