problem.
|
|
|
|
|
|
Major changes since last pkgsrc version:
68k core fixes (still unused); sms/gg sprite renderer draws from tile cache;
completely new c blitters; preliminary MSX and SC3000 drivers.
|
|
|
|
+ move the patch digest/checksum values from files/patch-sum to distinfo
|
|
|
|
shuffling (for details visit the homepage).
|
|
Changes since last version:
o Changed the cpu6502 core to use lazy flag evaluation.
o Changed the NES PPU to draw sprites from the tilecache.
o Added a bitdepth-independant generic palette system.
o Added CD audio playback to the PCD CD driver.
|
|
Fixed the instruction cycle timings in the cpu6502 core.
Cleaned up the per-driver menu interface somewhat.
Started adding support for multilevel per-driver menus.
Started adding menus for the Disk ][ drives (not working yet).
Added preliminary FDS disk write emulation (doesn't save the changed disk,
but whatever).
Added preliminary FDS timer IRQs (still need write support, but most of my
test images are playable now).
|
|
Changes from the web-page:
o Added driver-specific menu support to the X version.
o Broke all non-X versions (what, you didn't see this coming?).
o Added a reset menu item for the Apple ][ driver (it's now somewhat
usable).
o Fixed unix sound and CD interfaces to automatically detect what type
of system to compile for.
o Added support for Inserting/Removing FDS disks, and changing which
side is up.
o Fixed "Error 24" problem reading many FDS disks (still need write
support and timer IRQs).
o Fixed GTK version (yes, this one is tested).
o Fixed Makefile to allow overriding gtk-config (necessary for my system).
o More tweaks to the 68000 core (no it doesn't work).
o Cleaned up mapper 23 code (untested).
o Removed mapper vsync hooks (they weren't being used).
o Fixed NES palette mirroring (longstanding oops).
o More untested fixes to the Allegro and SVGALib ports (let's hope
they work this time).

Changes since the last version, from the authors web page:
Moved some event queue code out from pce.c to event.[ch].
Added automatic dependancy support to the Makefile.
Cleaned several things up to make porting easier.
Cleaned several things up to make cross-compilation easier.
Changed a couple headers to compile cleanly with a C++ compiler.
Added support for expansion cards to the Apple ][ emulation.
Added support for the language card to the Apple ][ emulation.
Added code to load more roms to the Apple ][ emulation.
Added preliminary Apple ][ disk support (can't use it without gdb, though).
Fixed color on Apple ][ text mode.
Added Apple ][ hires graphics mode.
Added a first approximation of Apple ][ lores graphics mode.
Added IRQ support to the emu68k core (no, genesis emulation still doesn't
work).
Added a new 6502 core (only used on NES right now, may be slightly buggy).
Made many improvements/fixes to the emu68k core (no, it _still_ doesn't
work).
Fixed genesis memory access to mask down to 24 bit addresses.
Fixed Apple ][ space bar key.
Removed the (unused) m6280 core.
Changed most NES mappers to not need to know how large the PRG ROM is.
Cleaned up the NES sprite renderer slightly.
Changed the video interface to not use procpointers.
|
|
Changes:
o Added keyboard support to Apple ][ driver (only works under X).
o Added a couple more instructions to the emu68k core (and still nothing runs).
o Added range checking to ROM accesses in the genesis driver.
o Disabled I/O logging of FM chip writes in the genesis driver.
o Fixed a bug with MMC3 IRQs (SMB3 fortress now works correctly).
o Cleaned up the NES PPU code somewhat.
o Cleaned up the SMS sprite renderers somewhat.
o Rebuilt command line parsing for X version and added (but failed to
document) a command to override system detection (needed to access the
Apple ][ driver).
|
|
o Fixed some problems with GG sprite clipping and tile rendering (only
affects 8-bit mode).
o Fixed X toplevel window to resize properly.
o Cleaned up some of the X video code.
o Added (untested) 24bpp support to X video code.
o Cleaned up the FDS emulation code.
o Added a lot of (inaccessible) extra FDS functionality.
|
|
Changes:
o Unified cd_freebsd.c and cd_linux.c into cd_unix.c.
o Added support for NetBSD CDROM (untested), and sound interfaces
(thanks to Thomas Klausner for the NetBSD changes).
o Changed the nes bank 4 and 6 I/O hooks.
o Fixed FDS mapper to compile again.
o Fixed some problems with the PCE timer.
o Changed the PCE VDP interface not to use procpointers.
o Added clipping sprites to the right side of the screen to the PCE VDP.
o Removed the old (disabled) ROM type identification routine.
o Fixed the battery file handling to not use a cheap hack to get the
filename (this breaks all gg savegames until you rename the battery
file).

NES, SMS, and GG with sound, PCE without, and has basic support for some
other systems (SMD, Coleco, Atari ][).
This will not work on MSB-machines, for lack of access. The code
should support it, so if anyone's willing...
