Slow Down 'button' of MKIII

[Giants]

Hi every Body !

On real ActionReplay MKIII for Amiga, they are switch to active or not the 'slow turn button'
UnderWinUAE, it is emulated ?

Warning, my question IS NOT how to slow down WinUae
I would like to know IF this 'button' is emulated, so... slow down Amiga BUT with MKIII
Not with modify WinUae configuration.

I don't know If I'm clear o_O'

It is not emulated. Not worth the trouble.

It is hardware feature that is hidden in PAL chips, it probably steals cycles from the CPU periodically but I am not interested in reverse engineering it.

This explains why I did not find this option <img src="images/smilies/smile.gif" border="0" alt="" title="Smile" smilieid="1" class="inlineimg" /><br />
Ok, no problem

I'm guessing it's an autofire for the _HLT signal.

I had the MKIII but never really used that slo-mo button.

Quickfix for your PC: just run 600 compression processes in parallel, while WinUAE is running: done.

I used it, but it messed up just about anything that used a custom copper list. :-)

That's what I always thought..

Just for information, I am actually creating a new page on my HomePage for the MKIII
http://sasfepu78.ddns.net/articles/MKIII.html

as I say in this webPage, In progress

Question I've wanted to ask for a long time how do I slow down WinUae like the ARIII use to do? It's quite useful, What's the key combination, it's usually +/-

The chip manufacturer is HYUNDAI not YUNDAI

Copper lists still runs normally.

Program does not use double buffering and uses copper to set bitplane/sprite pointers or program updates copper list bitplane/sprite pointers in vblank interrupt: some flicker is possible but nothing too bad.

Program updates bitplane/sprite pointer registers directly in vblank interrupt: total mess

There is no AR3 like slowdown but there is much better option: you can change emulation speed quite freely by changing FPS Adj. in Display panel (just tick the checkbox first to enable forced static refresh rate, without it long/short field/interlace affects refresh rate). This won't affect compatibility, program still thinks it is running normally.

Input panel has increase/decrease emulation speed options but they are currently broken.. (do nothing). Internally it does same as Display panel adjustment.

That seems like just what I want

Yep, exact.
It's Beta page
I change that, thks

Any idea of the mast chipset ? I see : TIF206 FS F74
I think it's a 74F74 but not sure...

Let me revive this old thread.
Has anyone saved the JEDECs (from @Giants) for the 5 PALs? I have a faulty ActionReplay MK3 here. I am sure I can repair it with the JEDEC files.
Sadly, the webpage of @Giants is not reachable anymore.

The slowdown function in MK3 is mostly to slowdown the computer in order to copy games with longtracks......

Perhaps this could help https://web.archive.org/web/20210716...les/MKIII.html

EDIT: doesn't seem to have the files saved :/

I wonder if that would work, I don't think burst nibbler made use of it l.
