*** 9.1 (15.02.1999)
- new: WHDLTAG_TIME_GET to get actual date and time (MrLarmer)
- fix: problems with some 68030 systems fixed (WHDLoad uses some
special hardware features in conjunction with the MMU
related operations, some hardware does not support this
(Apollo A630 and Magnum MK2 are known for this), on such
systems you can't enable the MMU/S option - otherwise the
machine will hang) (reported by Chris Thomas, Maxim Ilyn
and Jess Sosnoski)
*** 9.0 (17.01.1999)
- chg: performance of resload_LoadFileDecrunch improved
- chg: access fault handler for 68030 rewritten:
- better performance
- cia snooper implemented
- icm and alarm will be saved and dumped
- setting overlay bit (ciaa.pra) catched
- setting motor/step (ciab.prb) catched
- bad writes to ddra/ddrb catched
- blitsize check fixed, supports all except line-mode now
(ascending/descending mode, negative modulos, odd pointers
and odd modulos)
- a callback function can be setup (resload_Control) which
will called by WHDLoad if an Access Fault occurs, the
function can modify the bad access and decide if the
program should be continued or terminated, see autodoc for
further infos
- fix: potgo set to input mode now, fixes right mouse button problem
with ArcherMcLeanPool and JimmyWhiteSnooker (MrLarmer)
- new: WHDLTAG_VERSION_GET, WHDLTAG_REVISION_GET, WHDLTAG_BUILD_GET
for usage with resload_Control to get the major and minor
version number and the build number of WHDLoad currently
running, the build number is granted to be uniq and can be
used to distinguish between different sub versions (MrLarmer)
- new: pressing Ctrl-Amiga-Amiga will cause WHDLoad to quit,
depending on machine speed this may avoid cold reboots due a
not restored execbase (Graham)
- fix: Snoop works again on 68060, was broken in 8.2
- chg: the vector table is not write protected if Snoop on a 68060 is
enabled
- new: option ReadDelay/N to cause WHDLoad to wait some time between
reading files from disk and switching the OS off (Jeff)
- new: flag WHDLF_EmulTrapV to forward exceptions to the zero page
handler if the vbr is moved (Graham)
*** 8.2 (19.12.1998)
- chg: the vector table (VBR) is write protected now, to catch
invalid to accesses to it (MrLarmer), requires that the MMU
is used by WHDLoad, NoVBRMove is not set and no freezer is
detected by WHDLoad in memory
- fix: problems with PAL and NTSC in conjunction with Picasso 96
monitor drivers fixed (Tim Kovack)
*** 8.1 (13.12.1998)
- chg: detection of HrtMon 2.24 implemented
- fix: Access Fault in resload_Relocate removed
- new: some changes and enhancements for HrtMon 2.25
- fix: Snoop works again for 68030 machines (was broken in v8.0)
- chg: all unsaved registers after executing a resload function
(D0-D1/A0-A1 as far as they don't contain a return code)
will be destroyed explicit now, for compatibility reasons
*** 8.0 (22.11.1998) not public released!
- chg: if the write offset for a resload_SaveFileOffset operation
lies outside the current length of the file and therefore
the file must be enlarged before writing, WHDLoad tries now to
fill this area with $ee, if there is not enough memory
available for this, WHDLoad falls back to the old style by
using dos.SetFileSize(), with the result that the enlarged
area will contain random data
- fix: deadlock in switch routine fixed which occured when lightpen
has been activated (e.g. "Die Hard 2")
- fix: cia's will be completly initialized by WHDLoad now, and also
better handled during switch
- chg: also disk images will be cached dynamically now
- fix: small bug in DIC removed (MrLarmer)
- fix: resload_LoadFileOffset accepts also parameters upto the
BaseMem bound now (DarkAngel)
- new: flag WHDLF_NoKbd to allow NoVBRMove also for programs which
doesn't check the keyboard from the PORTS ($68) interrupt
- new: function resload_Relocate to relocate an standard AmigaDOS
executable in memory, beware: uses a lot of stack and is not
tested with all hunk types, see autodoc for more details
- new: function resload_Delay to wait a specified time or a button
to be pressed (time independed from PAL/NTSC display)
- new: slave can request expansion memory (fast memory) now
ATTENTION: slave structure has been enlarged
- new: TDREASON_MUSTREG (DarkAngel)
- new: WHDLTAG_IOERR_GET for usage with resload_Control to check if
all names have been fitted in resload_ListFiles and to
distinguish a file with a size of 0 from an nonexistent file
in resload_GetFileSize (Harry)
- new: option D/S for debuging, if enabled the software freezer
(Hrt/TK) will be activated at the first instruction of the
Slave
- new: flag WHDLF_EmulLineA to emulate Line-A opcodes if the vbr is
moved
- new: function resload_DeleteFile to delete files (MrLarmer)
- new: program SP which can save iff pictures from the new coredump
files created by WHDLoad, works for most standard picture
formats (Snoop* is required of course)
- new: sources for all programs except WHDLoad included, please note
that most of them are copyrighted
- chg: many internal changes, also the problems with BloodMoney and
CelticLegends seems to have been solved
- fix: Restart should work reliable now
- fix: small bug in ITD removed (Harry)
*** 7.0 (01.07.1998)
- chg: new revision scheme, version number of WHDLoad is now equal to
highest possible version number for a Slave, separate build
number
- new: new tag for resload_Control to setup a function to restore
destroyed custom registers during switch between OS and
installed program (Harry)
- chg: functions resload_LoadFileOffset, resload_SaveFile and
resload_SaveFileOffset can be used with a filesize of zero now
(Harry)
- chg: the functions resload_Protect#? are checking now if the
protected area matches the current SSP, if it does, WHDLoad
will stop and show a requester "Unacceptible Arguments", this
has been build in to reduce the likelihood of a Double Bus
Fault, thanks to Mr Larmer for reporting this problem
- fix: check of workbench arguments a bit more secure now
- new: new Slave flags WHDLF_Req68020 and WHDLF_ReqAGA, new
TDREASON_REQ68020 and TDREASON_REQAGA, new tag
WHDLTAG_CHIPREVBITS_GET for resload_Control, to handle
programs which require a MC68020 or the AGA Chip Set (Mr
Larmer)
- new: TDREASON_MUSTNTSC and TDREASON_MUSTPAL to terminate if the
installed program requires a specific display which isn't
enabled (Mr Larmer)
- chg: PreLoad now collects also files from sub directories
- chg: example sources (slaves/imager) reworked to assemble with
Asm-Pro v1.12 (still some problems with labels in macros,
but this is a problem of AsmPro)
- new: support for additional NewIcon in Install Templates (MrLarmer)
the following problems are known and still unsolved:
- no exit possible from BloodMoney/CelticLegends
- Nitro does hang with PRELOAD enabled, use WHDLoad v0.608 or disable
PRELOAD to go around this
*** 1.92 (08.06.1998)
- fix: problem with Clown'o'mania (©1989 Starbyte) does not work with
WHDLoad v1.1 has been fixed, the reason was a different
initialized ciaa.icr.tb bit, to fix this and future problems
WHDLoad does init the CIA interrupt mask explicit now, all
interrupts are disabled except the CIAA SP interrupt (used for
keyboard) which is enabled. I have tried some installs and it
seems to work ok, anyway it is possible that some installs may
no longer work because they may expect that some interrupts
are already enabled on startup - these installs must be fixed
for this new WHDLoad
- new: TDREASON_OSEMUFAIL to support the OS emulation module
- chg: the message for instruction stream access faults has been
corrected (Harry)
- new: option Expert/S, this option must be enabled to make core
dumps using the DebugKey/K/N now, the option has been added to
avoid that normal users press the wrong key by mistake (Harry)
- new: options ExecuteStartup and ExecuteCleanup to execute a command
at start and at end of WHDLoad
*** 1.1 (25.05.1998)
- fix: stack usage on resload_Decrunch and resload_LoadFileDecrunch
decreased, speed of RNC1 decrunching improved a lot, its a
really a good idea to patch the decrunch routine in games
with resload_Decrunch if it uses RNC1 !
- new: DIC can create partial images now (option SIZE/K)
- new: WHDLoad performs now a "SetClock LOAD" at exit
- fix: some minor fixes in the gfx degrading routine
- fix: disk-dma check in os-switch modified, it switches dma off now
instead of showing the white-color-cycle-bug-screen
(because it's nowhere documented else: red - copper cannot
switched off, blue - ints cannot switched off, green - blitter
is busy but dma is off; after pressing LMB WHDLoad continues
but it's undefined what will happen)
- new: new program "ITD" (ImageToDisk) to write disk images back to
floppy or RAD: can format the disk, can write partial images,
no verify, see documentation for more info
- fix: problems with second copperlist on reactivating os graphics
- new: blitter wait check if SnoopOCS/ECS/AGA enabled
- new: if available whdload will use reqtools.library instead
intuitions requesters now, because they are screen centered
and have better keyboard support
- new: with SnoopOCS/ECS/AGA all cpu used custom registers will be
dumped now
- chg: tooltypes NTSC/PAL will now affect the display init routine
(Intuition.OpenScreen()) therefore you need the appropriate
monitor files installed
- new: functions resload_Protect#? to snoop memory accesses in various
ways, very useful for developer... (requested by MrLarmer)
- new: function resload_LoadFileOffset which is similar to
resload_DiskLoad but for files
- new: flag WHDLF_NoDivZero for ws_Flags to prevent WHDLoad from exit
if a "Division by Zero" exception occurs
- chg: all resload functions has been reworked to no longer modify
registers a5 and a6, this solves problems with demos/games
which expect that the contens of these registers are valid
also in an interrupt, for example SWIV expects a5=global-data
and a6=custom-base, the only exception from this rule are the
functions resload_Decrunch and resload_LoadFileDecrunch when
working on rnc packed files, in this case a5 is temporarly
used (it is a bit hard to rewrite the whole decrunch
routines and I'm low on time of course...)
in general it is a good idea if the program you like to
install does'nt work with WHDLoad to check the interrupt
routines, if the interrupts make assuptions similar the above
(e.g a4=anything) you have to disable the interrupts before
calling any resload function and reenable after
- chg: WHDLoad checks now the current stackpointer each time the
Slave calls a resload function, if the SP is lower than $180
or outside the BaseMem area the program will be terminated and
WHDLoad shows a requester about, this should avoid problems
like destroyed vector tables or deadly double Access Faults
in conjunction with an enabled Memory Protection
- chg: it is no longer required that SetPatch is executed before
WHDLoad on 68040/68060 equipped machines because WHDLoad
determinates the current CPU itself now
- chg: for 68060 only (68040 also??): the newer versions of
68060.library (starting v41.1) does remap the memory $0-$1000
(the first page) to a fast mem location using the MMU, this
will make major problems if the option NoMMU is activated: in
this case WHDLoad will not change any MMU related registers
and this address translation will remain intact !!!
if the installed program tries to use this area for any dma
actions (e.g. a copperlist in this area) the results will be
unforeseeable, because the cpu will read/write the fast-mem
location and dma's the real chip-mem which contains random
data !!!
I don't want to disable the NoMMU option for 68040/060
machines, therefore the following has been changed: the
longword at address $1000 does now contain the value -2 which
is the copper instruction cend (was on address $300 in earlier
WHDLoad versions), the minimum BaseMemSize has been increased
to $2000. If NoMMU is selected and the above mentioned
address translation is active an requester will inform the
user about the existing problem.
- new: options ButtonWait/S and Custom1/K/N ... Custom5/K/N for
slave specific things (requested by Harry)
- chg: WriteDelay/K/N does also affect the FileLog/S feature now,
this means that after each write to the logfile WHDLoad will
wait the time specified via WriteDelay/K/N to minimize the
danger of filesystem corupption
- chg: install scripts has been reworked, PLEASE check them !
- chg: sources has been changed and new added, PLEASE check them !
- chg: WHDLoad is shareware now, read documention for more info

- new: option PAL/S to force PAL display on NTSC amigas
- new: options Cache/S,DCache/S,NoDCache/S to allow full user
control over the caches
- new: using MMU for memory protection and cache managment (!!!)
- new: Quit/Debug-key managment trough new options QuitKey/K/N and
DebugKey/K/N, every new slave should support this via the
slave version 4 extensions ws_keydebug and ws_keyexit,
