Recommended startup and cleanup settings for WHDLoad in UAE

[bladecgn]

I wonder if there are recommended settings to set via uae-control in the S:WhdLoad-Startup and -Cleanup scripts.


What I do is to stop networking on Whdload startup by using:
SYS:c2/uae-configuration bsdsocket_emu FALSE
and turning it back on cleanupby using:
SYS:c2/uae-configuration bsdsocket_emu TRUE

Is it good to turn on cpu_memory_cycle_exact for games and turn it off for workbench?
I do it to avoid graphics being too fast in some games, like the Giana sisters crack-loading screen.

Is there anything else you would recommend?

bsdsocket emulation does not support on the fly switching but it also shouldn't cause any problems with whdload. It does not have driver that would generate "spurious" interrupts.

Usually switching CPU speed to approximate is enough. Few games probably need more accurate timing.

Thanks for the info on bsdsocket.library


It is also good to turn off immediate blitter while playing WhdLoad Games. Some games have flicker otherwise.

You shouldn't need to have this set anyway; even when not using WHDLoad.

You should change 2 settings if you are using Workbench and running fast as possible and with JIT.

ExecuteStartup=uae-configuration cpu_speed real cachesize 0

ExecuteCleanup=uae-configuration cpu_speed max cachesize 8192

Check Paul's Guide: http://guide.abime.net/wb3.1/miscwhd.htm

Yes I do turn of JIT in the way you described, forgot to mention it. I also found out that only by using full cycle exact mode there are no graphics error in any game. Good games for testing are "Jet" and "F/A18 Interceptor".

WhdLoad-Startup
SYS:c2/uae-configuration cachesize 0 cpu_speed REAL cycle_exact TRUE
[CPU Frequency is set to "4x (A1200"]

WhdLload Cleanup
SYS:c2/uae-configuration cycle_exact FALSE cpu_speed max cachesize 16384

Als it is a good idea to turn on the blitter wait function in WinUAE as some gmes need it.


In WHDLoad-Startup I use now:

SYS:c2/uae-configuration cachesize 0 cpu_speed REAL cycle_exact TRUE cpu_multiplier 8 waiting_blits automatic
If $Scanlines EQ "Yes"
  SYS:c2/uae-configuration gfx_filter_scanlines 70 gfx_filter_scanlineratio 19
EndIf

And in WHDLoad-Cleanup:

SYS:c2/uae-configuration cycle_exact FALSE cpu_speed max cachesize 16384 immediate_blits TRUE waiting_blits FALSE cpu_compatible FALSE
If $Scanlines EQ "Yes"
  SYS:c2/uae-configuration gfx_filter_scanlines 0 gfx_filter_scanlineratio 17
EndIf

The Scanlines-variable controls if Scanlines are enabled or not.
