WinFellow - Amiga Emulator for Windows Subversion (Archive)

* Fixed ea evaluation for 020+ to work with PREFETCH

Removed MEMORY_ODD_ACCESS, SOUND_C, USE_NEW_SPRITE, GRAPHEM_C, USE_C and USE_ASM
defines in defs.h and defs.inc, these are obsolete and not used anywhere.

Turned off PC_PTR and turned PREFETCH on.
The reason for this is that the HRM states the only officially supported
reset code relies on the prefetching of data in the 68000.

Fixed compilation errors when not using PC_PTR. (short jump out of range)
Increased delay in cpuRaiseInterrupt() to 10. Revenge of the mutant
camels needs this. This was changed to 4 to help Lotus work.

Changed return value for ddrb in CIA B to 0xff. (ref: HRM. Probably not important,
but it should be right.)
Added code to map kickstart overlay on or off in ciaWriteApra()

memoryChipMap(): Added parameter for overlay and code to map the kickstart to $0.
memorySoftReset() and memoryHardReset() now map the kickstart to $0.
Included rserdatr() in the io-map, though it now only returns 0. The Kickstart
won't progress after Guruing unless it sees a zero there.

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
