...will be coming soon.
Yeah, see what I did there?
Anyway... a lot of people have been asking for a playable demo so we're going to shift focus and produce the demo we originally intended for the public. This is a special build of the game that has a special feature; it will use the backup RAM to record your gameplay. Of course, it can be played without recording it as well, so you can practice before the recording run. Why will it record? Because whoever records the best demo will have their playthru made a part of the finished product.
So... you can record your gameplay and send us the backup RAM file(s) from your emulator of choice, and if your playthru is the best, we'll officially make it part of the game's opening cutscene. It will also have an option to playback the demo you've recorded.
Normally, there's only enough backup RAM for roughly 34 seconds of gameplay. I am pretty sure that there are emulators that can max out the BRAM circuit, up to the point where there'd be just over 2 minutes' worth of gameplay time. If not, then I will bug the Mednafen author to make it happen.
The game will automatically detect the amount of BRAM present and will have a countdown timer so you know how much space you have left to complete the game.
