Circus Charlie (Famicom / NES) [coin trick / coin secret] 234700pts

No savestates, no cheats, no slowdown.

Played on a real hardware - Famicom HVC-101 (Famicom AV), Everdrive N8 flashcart.

Stage 1 coin trick / coin secret used. Read more below.

When player jumps backwards above fire pots in certain moments, then after landing, coin pops out of fire pot.
Those certain moments are tied to a timer, so to get a coin, player must be above fire pots when bonus is equal to:
from 4390 to 4300,
from 3790 to 3700,
from 2390 to 2300,
from 1790 to 1700,
from 390 to 300.
I name those moments later in a description as "window of opportunity".

Above rules can be told in short: "coin shows when thousands are even and hundreds are equal to 3 and when thousands are odd and hundreds are equal to 7".

Those coins are infinite source of lives. Look at calculations:
Each coin gives 5.000 points. In each "window of opportunity", player can grab 1 coin, so coins solely give 25.000 points.'

One live is granted each 40.000 points, so player have to get 15.000 points from other sources. The easiest and fastest way is to jump forth and back above fire pot (200 points each jump), even better jump through fire rings when jumping above fire pot (400 points).

This is doable in given amount of time, so player can safely lost a life due to end of the timer. Ultimately, it leads to a 1-up loop - get a life because of points, lost a life because of the timer; rinse and repeat.

Above words are proven on the video.

It is possible to spawn two coins in one "window of opportunity" but it is hard to grab them both, as you see in certain moments of the video.
