floppy.c

- floppyHasIndex() tested motor_tick == 0, when motor_tick was
oddly aligned, this test would never trigger since the code reads 2 bytes
forward every time. The loading then halted in Beast 3.

- The disksync value in the mfm_data was not word aligned, so the code never
saw it. I added a temporary fix in floppyEndOfLineC() that steps one
byte back to synchronize the mfm-stream to it.
A more comfortable solution is to rewrite the code that reads word-wise to read bytes
into a word-window instead.

caps_win32.c

In capsLoadImage(), there was a minor error in the tracks calculation
that caused floppy[].tracks to be doubled. (84 vs 168). It allowed
Beast 3 to step outside the initialized tracks.

code cleanups

Commit of Torsten on 2004-06-06

floppy.c/.h, caps_win32.c

- timebuf[] renamed

caps_win32.c

- change to capsLoadTrack(); it now also makes sure an even amount of memory is reserved and filled up
with zeroes prior to loading; I just like it better if the memory area is cleanly initialized beforehand
this does not result in an obviously different behaviour, it's just to be on the safe side

floppy.c

- floppyNextTick(): modulo is now the MFM tracklength or the tracklength+1 if it happens to be odd (since
the code reads word-wise I think it always has to be an even number); that way now SWIV also boots up,
though it still doesn't fix the Dungeon Master loadup (I've also tried that, doesn't work for me too)

floppy.c

- removed clearing of writeprot flag from floppyDriveTableReset(); added code to set the file_offset
for trackdata in IPF images to 0xffffffff so that writing data back wouldn't write back to offset 0
in the file even if it was attempted again
- I'm still playing around with various modulo values in floppyNextTick(); I assumed the value should
be the track length, but after I changed this loading randomly works or doesn't work..

winfellow.dsp

- removed the files infblock.c/.h, infcodes.c/.h, infutil.c/.h from the project
(these are no longer present and have been moved to other files in the meantime)
- added files caps_win32.c/.h to the project file

Commit of Torsten on 2004-06-6

floppy.c, caps_win32.c/.h

- experimental "flakey" image support (multi-revolution-tracks) added; I inserted the loader into the
floppyNextTick() routine, since I thought it would make sense to handle there when a track has been read
and a new revolution should be loaded

busa.s/ciaa.s/coppera.s/cpua.s

- added pushad/popad around calls to 'busScanEventsLevelX' functions

bus.c

- removed some outcommented stuff

turned "profile" option off due to a compiler warning
