Hi,

I have proposed last week a patch for the Emerald Classic Plus from Novag
to correct the bug of the AT level.
47E7 : 20 in place of 10 !
Very short! ...Too short ? ... I don't think so!

I have beautiful graphics, but it is not possible to insert there here.


First, the user manual is false.

Levels of ECP are :
Theses values ares the maximum of seconds used by the computer for one move.
So the really average time for the level is the quater of it (user manual is true).
For example at AT11, 160/4 so 40 secondes by move.
In opening, the computer plays in 1 seconde by move, so it gathers many seconds in advance.
At end of the opening, it takes these gathered seconds with the value of the current level, and it is new maximum time by move. So the average time is also modified (1/4 of it).
If now gathered seconds are all used, the average time is decremented step by step to the value of the current choose level.
In the original roms, the counter of gathered seconds is not used, but a light variation of time by move existe (but without changing the maximum time by move) , probably modified by the search.

If you want, I have 2 games at AT11 with some counters of time used internally.

Cordialy,

Hi Mychess.

Interesting - quite complicated time management.

But what exactly does your patch do?
Does it change this: "In the original roms, the counter of gathered seconds is not used"?

Regards,
Franz

Hi Fhub,

In Sapphire, TR and AT code are common and use seconds accumulator and others.
In Emerald Classic Plus, too!
But I found a test where level are compared with 0x10, and if it is only
below there is an initialization of seconds accumulator (different to 0x0).
But he ECP has double of TR levels, so it would be 0x20 to include TR and AT levels with this initialization.

Is it understandable in my english (not google translate, real time!)?

In a game at AT11 in 80 moves, it took 3240 s for white and 3052 s for black, so 40.5 s/move and 38.1 s/move, splendid horizontal asymptote! ( with the longuest white move of 122 s, below the max of 160).

Cordialy.

Yes, I think I got it - this now makes the doubling of this byte from 0x10 to 0x20 understandable.

Thanks,
Franz
