This page gives me 35 pages of Pascal source code and a page at the bottom
with links to a .zip file and a .bxy file (minor nit: can you put the
links to the archives at the top so we don't have to scroll down through
35 pages of source to get to them?  Not a big deal either way, though).

I can download the .zip and .bxy files just fine, but PMPunzip chokes on
the .zip file with a memory error (I have 5.125 Meg).  I'll let the
emulator people report whether it works for them.

The .bxy file unwrapped to a ShrinkIt archive which unpacked with Balloon
just fine.  So no problems at all downloading or extracting the archive.

The problems arose when I tried to run the resulting programs.  Mandelbrot2
had a yellow band at the bottom of the main menu stretching from the bottom
of the screen up to about 1/3 of the way up the buttons.  The buttons were
orange, which seemed to be an interaction with the yellow band.

Entering the Mandelbrot set in 640 mode was correct at first, but selecting
a region caused problems.  It re-drew the screen from the top down in pix-
ellated form (correctly from the way I remember the program working from
way back), but then it replaced the pixellated screen with a repeating
pattern about the size of a lo-res block.  Selecting a new region causes
it to pixellate and zoom in on the repeating pattern.

The Mandelbrot set appeared to work correctly in 320 mode, but returning
to the main menu found it to be shifted off the screen to the right.  The
rightmost button says "Qui" and then gets cut off.  At the top of the screen
the main menu says "Beautyedzoomet of that point".

The "About the author" screen seemed correct, but returning to the main menu
from that screen revealed an olive green band across the bottom of the
screen extending from the bottom to just under the "colour mode" line.
The buttons were brown with light purple text.

Mandelbrot 320's main menu was titled "BeautyedzoomChean (GS Lover)" and
displayed similar behavior to Mandelbrot2.

Mandelbrot 640 had a full main menu and seemed to be working correctly.

I have a stock ROM 3 GS running System 6.0.1.  The behavior of the pro-
grams did not change by shift-booting, so it's not an init or DA problem.

BTW, the version number on all of these programs is 2.1.  Just out of
curiosity, I ran the version of Mandelbrot II I have on my hard disk.
It is v 2.2 and runs correctly in all modes, as far as I can tell.

I don't know what happened, but you have some really weird graphics going
on in v 2.1.

Hope this helps,
Mike
