WinFellow - Amiga Emulator for Windows Subversion (Archive)

Added prototypes for the memoryOVLXXXX() functions.

Added read functions for ROM overlayed to address $0
memoryOVLReadByte()
memoryOVLReadWord()
memoryOVLReadLong()

busa.s

- removed references to sprite assembly files

graph.c

- replaced calls to assembly function spritesMerge by a call to the converted C version

sprite.c/sprite.h

- added functions spriteMergeDualLoresPF2loopinfront2, spriteMergeDualLoresPF1loopinfront2, spriteMergeDualLoresPF1loopbehind2, and spriteMergeDualLoresPF2loopbehind2
- added functions spriteMergeDualPlayfield, spriteMergeHires, spriteMergeHires320 and spriteMergeLores
- added converted from assembly function spritesMerge_C

winfellow.dsw

- removed sprite assembly files

removed files:

spritea.s
spritea.mac
spritea.inc (2x)

graph.c

- added calls to graphPlayfieldOnOff() at the end of function wdiwstrt() and wdiwstop(), this fixes graphical glitches within the playfield emulation (for instance improves Leander, Hugo 3 and Walker)

sprite.c

- some tweaking of the sprite handler (this is now v1.3), which fixes Leander and improves Seek & Destroy and Shadow of the Beast 3

sprite.c

- removed wrong code from function spriteProcessActionList, which was left after some testing

wgui.c

- led is (again) turned off when WinFellow starts up

busa.s

- added pushad/popad to make call to C code somewhat safer

spritea.s

- the correction of the x position is now applied in the spritesMerge function, instead of the spritesDecode

graph.c

- changed code within the function graphEndOfLine_C to handle sprites more precise
- removed function spriteHack

listtree.c/listtree.h

- added functionality to function listFree (return a pointer to the remaining list)
- added some comments

sprite.c/sprite.h

- implemented a new sprite handler (version 1.2) which should be more compatible then all previous ones
- added functions asprxptl, asprxpth, asprxctl and asprxpos ('a' stands for apply)
- rewriten functions wsprxptl, wsprxpth, wsprxctl and wsprxpos
- added function spritesDMASpriteHandler which embodies the new DMA sprite handler
- added function spriteActionListsClear and spriteDMAActionListClear
- added function spriteProcessActionList which embodies the emulation of the sprite hardware within Denise
- added function spriteSetDebugging which can be used for debugging

kbdrv.c

- added some comments which are handy when debugging sprite handling

*** empty log message ***

raiseInterrupt()
Changed delay from 38 to 4, since code in Lotus seem
to indicate this value was way too high.

rdskbytr():
Added reporting of the last byte from the disk through
this register. Kickoff II Final whistle and maybe
Little computer people depends on it.

floppySectorMfmEncode():
Changed data filled into the unused bytes of a sector
from 0x55 to 0. Clownomania's loader has a checksum
routine that assumes these words are zero.
