Looking for someone way smarter than myself to add in a DAS meter for the Nintendo/BPS (Non-Tengen) Tetris. Either a hack or a game genie code would be appreciated, just looking for something to play on original hardware. There is a script below that will show a meter with FCEUX, but I'd rather not emulate.

This code wasn't written by me and taken from this youtube video: 


Code:

local cnt = {};
for i=0,18 do
	cnt[i] = 0;
end;

local prev;
local pieces;

while (true) do
	local das = memory.readbyte(0x0046);
	--delay is gravity and ARE counter
	local delay = memory.readbyte(0x0045);
	prev = pieces;
	pieces = memory.readbyte(0x001A);
	local test = memory.readbyte(0x0019);
	
	if(pieces ~= prev) then
		cnt[test] = cnt[test] + 1;
	end;
	
	gui.text(100,16,"Gravity/ARE: "..delay.."");
	gui.text(100,8,"Next Piece: "..test.."");
	gui.text(200,0,"Pieces: "..pieces.."");
	
	for i=0,18 do
		gui.text(220,(i+1)*8,i..": "..cnt[i].."");
	end;
	
	gui.drawbox(5, 0, 7+4*16, 5, "magenta");
	
	for i=1,4 do
		gui.drawbox(6, i, 6+4*das, i, "green");
	end;
	
	gui.drawbox(5+4*10, 1, 5+4*10, 4, "white");

	local inp1 = joypad.read(1);
	if(inp1.left) then
		gui.text(5,8,"<L");
	elseif(inp1.right) then
		gui.text(5,8,"R>");
	else
		gui.text(5,8,"--");
	end;
	
	FCEU.frameadvance();
end;

 

If you want a game genie code, it's going to have to replace something that's already on screen and updated regularly. Like one of the statistics numbers, or at the top where it says 'lines'.

Which would you prefer?

Replacing any or all of the statistics would be awesome. If just one though, then probably the line/ I piece.

Try these...

Replaces the 'Level' with 0x46, listed in the code above as 'DAS'
Best I could do in a half an hour.

Or these..

TEOPPIPI
TKXPLIPY

Replaces the first 0 of 'Lines' with 0x46, listed above as 'DAS'

Woah sweet, the one at the level area is fantastic! Thank you very very much, I am new to this forum is there any way I can give you props or anything?

Thanks is enough.

You'd be surprised how many people I've helped on various forums, who didn't say 'thanks'.

To me, it was like you gave me a little Sudoku puzzle, it kept my mind occupied for a little while, and I love Tetris, btw.
