Hello,

How to enable TURTLE MODE?  It is just NOCACHE?  Tried to search and cannot find info anywhere.

TIA

Turtle Mode is automatic when a WHDLoad slave disable caches.

Anyway you have the file WHDLoad.prefs in S and you can configure it to enable Turtle Mode and diable SuperScalar:

ExecutePostDisk=ApolloControl TU=1 SS=0
ExecuteCleanup=ApolloControl TU=0 SS=1

Set these lines in your WHDLoad.prefs file.

The first line enable A500 Turtle mode and disable SuperScalar,
second line re-enable max speed when you exit from a game.

If you choose to do it this way then it means that Turtle mode will be activated for EVERY WHDLoad game, even for ones where you might NOT want it activated, such as some 3D games.
 
The alternative would be to simply enable it on a per game basis,as needed, by using the NoCache tooltype.

Turtle mode is automatic, it's related to every single whdload SLAVE, you have no choice to disable it by simply using NOCACHE or CACHE tooltype/sintax.
 
  You have only the choice to set the type:
 
  A1200 apollocontrol TU=2
  A500 apollocontrol TU=1
 
  This was a change that came after the old Core 7, where you had the ability to turn Turtle mode on or off with the F11 key.
 
  Now it's not possible anymore.

The Apollo 68080 CPU can run it 4 different speed.
This means you have full speed, plus 3 "turtle/game" modes.
You can control this with apollocontrol
and also change this with the joypad this during runtime of a game.

You can see a picture showing and explaining which button combination to push - on your ApolloOS in the Tools folder.

Using the "Cache" tooltype for WHDLoad games works for me for speeding up games like Alien Breed 3D and AB3D2.

@Sean Sk,

Yes, agree but if you want full speed, you must change TU=2 or 1 to tu=0 in a first time and after that, using "cache" in whdload expert mode. If you let Tu=2 (A1200 speed) and use "cache" options, it will be fast and if you use Tu=0 and "cache", then, speed is full and so smooth ;-)

Could you check, if it works for Barbarian from Palace (Part1)? For me the game runs still way too fast. Thx in advance.

Can you post the picture here? Is F12 to toggle among the Turtle mode not possible anymore?

@Chris,

Tried with :
- T=2 : Game is very very fast..
- T=1 : Game is less faster but I agree, too fast to play with..

Some games don't work correctly (glitches on screen) with 10000 core on icedrake (LionHeart, super street fighter2 Turbo, Maupiti island, Black sect for example..)
