p96_uae_tweak



This features need the p96_uae_tweak program attached in this mail

It must run after P96 monitordrivers in userstartup



If you have copy this prog to c:



run >nil: c:p96_uae_tweak.



I also recommend to set P96 mem from the 4 MB AIAB config to 16 or 32

MB,because it work

faster .If not enough gfx card space is free you see flicker as before and

slower move



Restart whole winuae when you have increase gfx memsize and save the config.

I notice crashes when only reboot.



To test it you can boot AIAB open the screenmode prefs window.

Now put the screenmode prefs window to back and move it around under other

windows.

Now if the window move fast and do not flicker all work ok.

 

With that patch it is also impossible that P96 graphic actions can block

winuae,so you get no AHI 16bit soundstodder when doing large graphic

actions.

 

The patch split for this large P96 blits (>60 pixel)in smaller blocks and

check in all blocks if a 16 bit ahi buffer is free.No speedloss seen,no

stodder notice with 4ms AHI Latency.



Swapbitmaprastport (used for solid windowmoving and some slow layer

actions)is patched

to use a UAE blitter functions that direct exchange the data instead calling

3* eor  

It is faster and avoid the heavy flickering when move a smartlayer window

under another window 



                              restoretime (download from Aminet)



This set every second the clock to windows clock time.

You need this when you hybernate your PC and resume to get exact time.

If you need exact time (for compiler make) i recommend also to use this

because UAE cycletiming make diffrence of 1-2 sec in a hour.

It have no speedloss   



                              ahitweak



This is a program you can start from shell or user-startup

and allow you to tune the ahi driver for better latency,because on winxp the 

playpointer position have a delay depend on system and soundcard



I can reach with 

ahitweak 200 



latency of 4 ms with my sb-PCI512 on winxp (simular sb-live) 

to get hd-rec working with 4ms



You see thats more a function to get the best for realtime Music without special 

ASIO drivers



Most users dont need that



But if you have crackle problems WITH 16 BIT AHI 

play a song and try values of 50 200 500 2000 -50 -200 -500 -2000



Maybe that help 

                        p96refresh  (winuae only)

Start this program to get higher mousepointer redraw rates than 50 hz

with P96.Actions are seen immediatly after call.You can start this in your 

user-startup for automatic on boot 



Example:

 p96refresh 75 

set redraw rate to 75 hz.Best is if you set rate 

         to your monitor refresh rate or monitor refreshrate*2

         Dont set it higher or you get speedloss > 2%  



			rtg.library:   (help also on Standard UAE)

This avoid large slowdown and redraw problems in picasso96 with JIT

copy it in libs:pacasso96



			picasso96fix   (help also on Standard UAE)

This allow larger Screen Width than 1024 

start it BEFORE the loadwb instruction in startup-sequence



			uae_german     (help also on Standard UAE (i hope ?))

This is a German keymap to reach @\~{[]} with ALT-GR like windows

Copy it in devs/keymaps and choose it in the keymap-prefs





                         uae/uae.audio (winuae only)

This is the AHI Driver.This allow support for record and playback upto 96 khz



copy uae       to devs:audiomodes

copy uae.audio to devs:ahi



If you install correct the driver should show Version 4.3 Date 22.5.02 

and offer you only 1 Mode UAE hifi stereo++. 



This driver work fully independent from paula sound.For a speed 

boost on slower systems you can set paula buffer to 5 or 6 choose 11 khz mono

thats enough to hear system sound
