Give me NTSC Master clock & YM2612 clock for info) 18µs not differs? Differs sequences timing only? (because based on VBLANK) Is it right?

55.075kHz = 18.15µs
Problems with math?
Those calculations was from image measuring - As I told.

On your image noted 3.03µs. 6 channels -> 18.18µs. It's not same as you writed.
23 cycles / 3.03 µs = 7 590 759 Hz.
It's not same with label in bottom of your image.

Assuming 7 692 000 Hz - correct ...

In UMK3 too many DMA, is it reason why PCM played only 6500 Hz?
I made some test: I removed timer overflow check, and I got same 6500 Hz. But If I change timer to 5200 Hz, for example - it works well.
Wanna cool sound (((.

How many PCM you can mix and samplerate?
UMK3 can play maximum 2 PCM, each 6500 Hz. Quite ugly.

Thanks for info.

From picture

image measures gives:
19.1 +- 0.2 µs delay between switch channels returns.

I DON'T see 24 clock cycles between them ...

I just tired in searching for precise info.

Common formula:
18 * (1024 - TIMER A) microseconds

Timer A - all 1's -> 18 µs = 0.018 ms
But, I think it is not precise. Where it goes from?
I suppose 18µ goes from 1s / 53267 Hz =
18,773349353258114780257945820114 µs
But I'm not sure, in this.
And ...

I have already done some steps in this way.
I have implemeted one algorithm to do that, but it still not good enough.

I think, it is not new "Topic" or "Idea". So, there must be good software for doing it. I hope.

Author is you?
This program is quite big. Many dependencies. I don't like it.
Is there command line interface?

I need to find program or algorithm that gives such result.
I prefer command line interface.

Output: Coordinates, Size of boxes.
Condition: gold middle (tiles count)/(sprites count).

Big thanks.

I did some research... I wrote some script on Perl to extract and compare dumps of GEMS z80 driver from romset. Only dumps - not asm.
So summary I have GEMS dumps from 1331 rom, it's from 214 different games. It's 27 different GEMS dump from games. Only z80 code - main driver.
Not all ...

I'm glad that you got it. But, where I can get it?) And, is it latest version?

About midi2gems - I don't know, but I wrote gems2midi -_-

Ok, let's start.
I'm searching for GEMS devkits.
I spent few days already in google :D.
I've found only GEMS devkit for 2.1, and for 2.5.

But, nevermind. I want only latest possible version or best version of GEMS.
Where can I get it?) I see only one way: rip from some game, but...
I don't know ...
