This install applies to "Intro? Dentro? Mentro? Demo?" © 1991 The Silents.
This install requires WHDLoad to be in the path.
It can be found in the WHDLoad package.
To install from a different drive than DF0: select installation mode Expert.
The installed demo requires 0.5 MB ChipMem (+0.3 MB for preload).
It can be quit by pressing F10 or left mouse button
(key can be changed with Tooltype "QuitKey=").
- Full load from HD
- Access fault fixed
- Screen clear on 68010+ machines fixed (blitter+CPU->CPU only)
- CPU clear can be forced on 68000 machines with CUSTOM1
- Interrupts fixed
- Reset at end of demo patched to quit back to DOS
- NewIcon (created by me)
- Source code included as usual
- Quit option that works on 68000 machines (default key is 'F10')
This patch was requested by Frequent some days ago and this morning
when arriving at work I started to work on it. The code is nicely
optimised and this actually caused problems on faster machines.
Screen clearing was done with hybrid CPU+blitter routines, blitter
clears top of the screen and while the blitter is working CPU clears
the bottom part of the screen. This only worked correctly on 68000
machines and would have required different routines for any faster
CPU's. I have replaced all screen clear routines with normal CPU
routines which fixes the problem. If you have a fast 68000 machine
you can force the CPU clear routines with CUSTOM1=1 as they are only
used on 68010+ machines otherwise.
There also was a nice access fault, coder stored the hardware registers
but register a0 was undefined so they were stored at "random" memory
locations. I guess this was the reason why the demo didn't quit back
to DOS at the end but instead simply reset the machine.
Other than that the code is really good! Same for the design which is
really nice for a demo released in 1991. I always liked this nicely
designed one-filer so patching it was fun. Nice and fast vector
effects accompanied by a great tune by NHP and BKH make this one
still enjoyable more than 20 years after its initial release.
Those were the days...
