This install applies to "Test Drive II - The Duel" © 1991 Accolade.
You can also install level disks and car disks.
This install requires WHDLoad to be in the path. It can be found in the
The installed program requires 0.5 MB ChipMem and 1 MB OtherMem.
It can be quit by pressing num '*' (key can be changed with Tooltype "QuitKey=").
The game requires an installed A500 Kickstart 1.3 image.
The kickstart image must be located in the directory "Devs:Kickstarts" and
must be named "kick34005.A500". The image can be extracted from a A500 with
tools like 'GrabKick' or similar which can be found on aminet.
If the image is of wrong version or altered in any way WHDLoad will quit with
an appropriate requester.
Additionally the file "kick34005.A500.RTB" must be installed in the same
directory as the kickstart image. It can be found in the archive
"util/boot/skick346.lha" on aminet.
If you have problems with this installation please try and get a newer
version of this package from the WHDLoad WWW-Page. If that doesn't help try
some Tooltypes like NOCACHE, NOAUTOVEC, NOVBRMOVE, NOMMU, PAL or NTSC. If
that also fails, please inform the author via the Bug-Report-Form which
can be accessed on the WHDLoad WWW-Page.

Incredible. About more than 15 years after trying to find the flickering bug, finally figured out the issue...
The game uses double buffering, but on fast machines (for some reason I didn't investigate)
it switches the copperlists in the middle of a frame while the blitter is still drawing stuff.
So gives the impression that the game isn't double-buffered when it is!
My fix was just to wait vertical beam until it matches the value of a
slow machine! and the flickering is completely gone!
The blitter operations aren't fast enough to draw more frames. But wasting time waiting for the
end of beam is slightly annoying when the game could be faster...
At least the use of fastmem means that the game loads slightly faster.
