|
||
2019-01-05

|
||
|
||
2018-03-08
|

Release of 2.0.11 source code and Win32 binaries.
|
||
+ No change from preview 3
|
||
2018-03-06

+ Improved desfx c64 IO banking handling and automatic decrunched area
|
||
detection.
|
||
+ sfx: Detected in-file type exported making target auto detection possible for
|
||
some sfx bin and sfx <addr> (not sfx basic or sfx sys).
|
||
+ sfx: Applesingle file write now writes the header descriptors in in ascending
|
||
order, suggested by Oliver Schmidt.
|
||
|
||
2018-02-20
|
||
Release of 2.0.11 preview 2
|
||
+ Fix compression improvement loop crashing bug exposed by the thread safety
|
||
changes for library compilation, reported by Lasse <20><>rni.

|
||

|
||
+ Add sfx bin directive as a shortcut for creating sfx files with as little
|
||
impact on memory outside of the decrunched area as possible. Perfect for
|
||
crunching Apple II binary files.
|
||
|
||
2017-12-25
|
||
Release of 2.0.10 source code and Win32 binaries.

|
||

device number address.
|
||
|
||
2017-12-09
|
||
Release of 2.0.10 preview 2
|

+ Add used encoding to the crunch_info struct returned by core crunch func.
|
||
+ Rework core compression core to not use local static vars to simplify use
|
||
when compiled into a library.
|
||
+ rework -C into a generic favor speed flag and make it disable the crunch
|
||
result changes too.
|
||
+ Improve crunch result slightly by also consider same length sequences at
|
||
larger offsets too (but by doing this also slowing it down).
|
||
|
||
20170708
|
||
Release of 2.0.10 preview 1
|
||
+ Add a brief output mode enabled with -B, suggested by both Daniel Hotorp and
|
||
Bacchus independently.
|
||
+ Display progress indication only on ttys and not when output is redirected,
|
||
inspired by input from Daniel Hotorp.
|
||
+ Make it possible to add offset and length to plain and prg file loading.
|
||

+ More portable by not using negative exit codes.
|
||
+ Add new keyword systrim to the sfx command. It behaves like the sys keyword
|
||
but will also remove the sysline from the loaded infile.
|
||
+ Exit with an error if the parsing of the sfxdecr.s fails. This might happen
|
||
with user provided assembly given by the options -x -X -s -f, reported by
|
||
Stefan A. Haubenthal.
|
||
+ Change -mtune flag to make exomizer build on more platforms "out of the box".
|
||
|
||
2015-09-21
|
||
Release of 2.0.9 source code, Win32 and DOS binaries.
|
||
+ Fix gcc-compiler warnings.
|
||
+ sfx decr src comments echoed to stdout, reported by iAN CooG, fix by soci.

||
+ NULL pointer dereference crash, reported by Flavio, fix by soci.
|
||
|
||
2015-09-20
|
||
Release of 2.0.8 source code, Win32 and DOS binaries.
|
||
+ Fix bug reported and analyzed by Adrien Destugues. The ECHO token in asm.y
|
||
collides with the flex ECHO macro. The cause is that Bison 2.3a and newer
|
||
stopped to generate defines for the declared tokens. To resolve this the ECHO
|
||
token has been renamed to ECHO1.
|
||
+ Add -E flag to not write the encoding to the outfile.
|
||
+ Remove max nr of chunks limit from the chunkpool allocator.
|
||
+ Enforce match max_len everwhere, bug reported by Zik / Futurs.
|
||
|
||
2013-04-14
|
||
Release of 2.0.7 source code, Win32 and DOS binaries.
|
||
+ Bugfixed commodore sfx targets to automatically disable irq when decrunching
|
||
over system areas. This together with moving the table to zero-page,
|
||
-Di_table_addr=0x2, allows decrunching $0200-<end of mem> without corruption
|
||
for all commodore targets except for the vic20-configs without a 3kB memory
|
||
expansion since they have a memory hole at $0400-$1000.
|
||
+ Bugfixed z80 decrunchers from Metalbrain.
|
||
+ Bugfixed sfx c16/plus4 target where the default irq could corrupt memory
|
||
while decrunching data that covers $07f6-$0800, reported by Luca/FIRE.
|
||
+ Bugfixed sfx c16/plus4 target where the default decrunch effect could corrupt
|
||
memory while decrunching data that covers $0be7, reported by Luca/FIRE.
|
||
+ Added feature to sfx-mode that complains if the data it too big to fit in the
|
||
available memory of the selected target, suggested by Luca/FIRE.
|
||
+ Added c16 target, -t 4, like -t4 but with smaller memory, suggested by
|
||
Luca/FIRE.
|
||
|
||
2013-01-27
|
||
Release of 2.0.6 source code, Win32 and DOS binaries.
|
||
+ New improvements to the z80 decrunchers, again smaller and faster.
|
||
|
||
2013-01-12
|
||
Release of 2.0.5 source code, Win32 and DOS binaries.
|
||
+ Add -C and -M <length> flags that trades crunch result for speed. It is now
|
||
possible to really speed up crunching, even for "worst case"-type files.
|
||
+ Now skips the DAG traversing of the final pass if the encoding hasn't changed
|
||
since the previous pass.
|
||
|
||
2012-08-16
|
||
Release of 2.0.4 source code, Win32 and DOS binaries.
|
||
+ Bug in z80 decrunchers fixed by Metalbrain. Thanks goes to Herv<72> Monchatre
|
||
and Tim Riemann (Octoate) for reporting.
|
||
+ Implement sfx basic for the Apple II target.
|
||
+ Improve documentation slightly for the sfx and level commands.
|
||
|
||
2012-03-25
|
||
Release of 2.0.3 source code, Win32 and DOS binaries.
|
||
+ z80 decrunchers improved by Antonio Villena, now smaller and faster.
|
||
|
||
2011-08-19
|
||
Release of 2.0.2 source code, Win32 and DOS binaries.
|
||
+ Added 6809-decruncher contributed by Edouard Forler.
|
||
+ Fix language errors in the documentation. Thanks to Csabo/LOD.
|
||
+ Remove bogus printout about the default decrunch effect when using a custom
|
||
decrunch effect. Bug reported by Csabo/LOD.
|
||
+ Fix bug that prevented the correct error message from showing when trying to
|
||
combine a basic start and a non rom config for the sfx command. Bug reported
|
||
by iAN CooG.
|
||
|
||
2011-02-06
|
||
Release of 2.0.1 source code, Win32 and DOS binaries.
|
||
+ Fix bug in log.c that caused the desfx command to loop if the log level was
|
||
lower than debug. Bug report by iAN CooG.
|
||
2011-01-22
|
||
Release of 2.0 source code, Win32 and DOS binaries.
|
||
+ Fix bug in sfx decruncher setup where data was copied unnecessary. Triggered
|
||
by using -Di_load_addr, reported by nbla000
|
||
+ Add i_line_number symbol to be able to change the default line number of the
|
||
basic line of the sfx decruncher. Feature suggested by Chicken
|
||
+ 6502 emulator core now features memory read/write callbacks
|
||
+ Add desfx -e flag to override the automatic entry point detection, feature
|
||
suggestion with patch by iAN CooG/HokutoForce. (Patch reworked somewhat,
|
||
error handling added)
|
||
+ Fix desfx handling of files that decrunch to and including 0xffff, Bug report
|
||
with patch by iAN CooG/HokutoForce. (Patch reworked somewhat, end addresses
|
||
are exclusive everywhere else)
|
||
+ Fix argument handling of desfx, Bug report + patch by iAN CooG/HokutoForce.
|
||
|
||
2008-09-08
|
||
Release of 2.0beta7 source code, Win32 and DOS binaries.
|
||
+ Refactored some functions from exo_main.c and exo_helper.c into a new file,
|
||
exo_util.c so the testprogram could use them too.
|
||
+ Fixed a bug in exo_main where the sys/call basic token was mixed up with
|
||
the basic_txt_start. This confused thes sfx sys sub-command.
|
||
+ Fixed a bug in krilldecr.s. The handling of literal sequences longer than
|
||
256 bytes was broken.
|
||
+ Added a testprogram to test that the decrunchers in the exodecrs folder
|
||
works. This feature uses the 6502 emulation core to run test programs. It
|
||
tests literal sequences longer than 256 bytes and run lengths longer than 256
|
||
bytes for all four decruncher variants, backward, forward, streaming and
|
||
chunk streaming.
|
||
+ Added a z80 decruncher contributed by Metalbrain.
|
||
+ Added an experimental desfx command that should be able to decrunch sfx
|
||
crunched files. Uses the 6502 emulation core to run the sfx-decrunchers.
|
||
+ Added a 6502 emulator core.
|
||
+ Fix rare situation when sfxdecr.s failed to assemble.
|
||
+ Improve the help text when no sub-command is given.
|
||
+ Improve the handling of ROM/RAM-banking and NMIs for the atari target in the
|
||
sfx decruncher.
|
||
+ Fix broken op definition ldy abs,x in the sfx assembler, bug reported by
|
||
Stefano Tognon.

||
+ Fix length field error in generated Apple II file header.
|
||

|
||
-fomit-frame-pointer. Bug reported by iAN CooG/HokutoForce.
|
||
+ Add multipass functionality to the assembler in order to be able to do more
|

complex things in the decruncher source.

+ Added flag -x<effect assembler fragment> to the sfx command.
|
