for the best performance my recomendation is use amiga version of ishar 3.
To do this you need: AMIGA 1200hdd or,
Winuae, Ishar 3 AGA in adf files , kickstart 3.1 A1200 ROM, and workbench OS 3.1.
winuae configuration is: CPU= 68EC020+FPU with "more compatibile" option
Chipset=AGA with defalut options
ROM= KS ROM v3.1 (A1200) rev 40.68 (512k) or better
RAM= Chip 2 Mb Fast 8 Mb
Hard drives=device-dh0 volume named as sys
device-dh1 volume named as work
when you start real or emulated amiga with hdd, first install workbench 3.1 on dh0 partition, make dir on dh1 partition named as ishar3 or whoever you want and copy all files from game disks to this drawer.
Dont use orginal ishar3 install aplication, becouse it has many bugs and game will not run.
After copying all files, restart amiga or winuae and "start with no startup-sequence".
in amiga dos window write: loadwb and press enter, after this you will see small info window, click CANCEL
three times, next write: endcli and press enter.
Now you have pure amiga system with over 2 mb of chip memory wich is needed to start the game.
go to game folder and press start icon, game will run, next click on language and silmarils logo.
Attention!!! don't press ESC key when you see the game demo, if you press ESC,game will not run.
Wait and watch the demo until you see game menu, then you will know what to do
.
Amiga version working 3 times faster than PC version and it contains less number of bugs.
so if you have WinXP, better is use winuae-amiga emulator instead DosBox
