[comp.sys.atari.st] GCR software compatibility

Here is another GCR compatibility report.  Dave, are you out there?

The game Corruption (Mac disk) causes an "Illegal Instruction Error" when run.
(It's aptly named.)

The Spectre crash page looks like this:

SR = 00002200  PC = 00000020
Last LineA PC: 0000E020  Last LineA Trap: 0000A746  Last Line A0: 000E0806
USP= 000392AA  SSP= 000C7762  SR (T.S., .IPL, ...X, NZVC) = 00002200

R     0        1         2         3          4        5        6          7
D 0000FFFF  00000000  FFFF0000  000001FC  000001FC  0000FFFF 53545253  00000000
A 00000010  00000000  000EF6D8  0000CC1C  0000D054  000C7D60 000C798C  000C7762

I don't know if it's copy protected; it may very well be.  Is this program
already on a (non-)compatibility list?

Here's my setup:

I have a 520 upgraded to 1Mb, with a Diverse Data Products MFD 1440 paired
DS drive unit - I ran speed.prg - both A: and B: check out to 300 RPM exactly.
I have pre-1.4 TOS on ROM. Atari mono monitor. 128K Mac ROMS. GCR last in chain.
I am running Spectre 2.3 with the factory settings: 832K, no cache, alt video,
no sound.  I have tried booting Mac mode with 5.4/3.2 and 6.0/4.2, and I have
turned sound off from the control panel before starting the program.
No HD20, No MacBeep, No ramdisk, no nothing.
