Getting this error while trying to generate trainer:
It seems adding custom sounds for activate/deactivate must follow specific bit sample rates. In order to circumvent this error, I had to re-sample my 352kbps wav files to 256kbps.
Also, the activate/deactivate sounds work properly for toggle (on/off), but not for enable/disable (on/off). For example, 'toggle on' plays 'activate' sound and 'toggle off' plays 'deactivate' sound. However, 'enable' plays the 'activate' sound, but 'disable' also plays the activate sound.
Thanks.

can you post a link to the wav file you originally used? I doubt it's the sample rate but more an issue with converting a binary file to xml
edit: Actually, I think just the filename would be enough for me to test. I think something extremely stupid is going on with the xml module
e.g if you name your file as "325462.pdf" it will fail, but "bla.pdf" will work fine
guess it's a rule that xml names may not start with a number...
i've uploaded a new build that fixes these two last issues

that's lea ebx,[eax-01] (67 8d 58 ff)
that 67 is quite useless here as far as I can see as it causes the first 32-bit of the result to get stored into ebx (which would truncate it to 32-bit anyhow)

yeah. I've just found this by simply attaching 64bit CE to itself and disassembling executable memory.

anyhow, it gives an opportunity to show off a new feature of CE
(not so useful in this case, but still funny:)

ldd.description="stupid method to get the address of eax-1"

return ldd.opcode, ldd.description
else
return nil,nil
end

Can we override assembler as well ?

yes, registerAssembler
| Code: |
registerStructureNameLookup(function(address): name, address OPTIONAL):
Registers a function to be called when dissect data asks the user for the name of a new structure define. If you have code that can look up the name of a structure, and perhaps also the real starting point, you can use this to improve the data dissection.
unregisterStructureNameLookup(ID)
registerAssembler(function(address, instruction):bytetable)
Registers a function to be called when the single line assembler is invoked to convert an instruction to a list of bytes
Return a bytetable with the specific bytes, or nil if you wish to let another function, or the original x86 assembler to assemble it
unregisterAssembler(ID): Unregisters the registered assembler
registerAutoAssemblerPrologue(function(script, syntaxcheck))
Registers a function to be called when the auto assembler is about to parse an auto assembler script. The script you get is after the [ENABLE] and [DISABLE] tags have been used to strip the script to the according one, but before comment stripping and trimming has occured
script is a Strings object which when changed has direct effect to the script
unregisterAutoAssemblerPrologue(ID)

Let say I want "NOP8" or "nop8" to be assembled into 0F 1F 84 00 00 00 00 00
Then, I will use this
| Code: | registerAssembler(
function (address, instruction)
if instruction:upper()=="NOP8" then
return {0x0F, 0x1F, 0x84, 0x00, 0x00, 0x00, 0x00, 0x00}
else
return nil
end
end

-You are right. The original files had numerical names, but I changed them to be alpha-based in lieu of overwriting the originals. Good catch.

problem with your script, 67 8D 58 FF is disassembled to "lea [eax-1]" instead of "lea ebx,[eax-1]"
and highlighting is messed,
and copy to clipboard doesn't work as should (ctrl+c or copy options from context menu).
EDIT:
Here my multibyte nops and padding:
http://forum.cheatengine.org/viewtopic.php?t=574426
There shouldn't be a problem with storing/reading data by using MOVDQA, ORPS, CVTTPD2DQ, PADDQ, MULPS, MOVAPS, MOVAPD
| Code: |
...
...
newmem:
...
...
...
...
...
PADDING 16
placeToStoreAlignedPackedSinglePrecisionFloatingPointValues:
dd 0
dd 0
dd 0
dd 0
...

just be aware of some extra nops when using address based assembling (or just not properly working at all)
aa scripts assemble code twice. Once with an absurd address to force out the biggest possible size the instruction will need, build up label locations, and then assembles the actual instruction. If afterwards it appears the extra bytes where not needed, it places nop's
(So I recommend managing the alignment yourself by placing variables first in the script/allocated memory)
and yes, in the example of mine could use some fixes, the return parameter is a bit wrong (used by some of the older disassembler parsers, and awareness of the visual disassembler)
| Code: |
unregisterGlobalDisassembleOverride(assemblerfix)
function assemblerfix(sender, address, ldd)
local bytes=readBytes(address, 4, true)
if bytes[1]==0x67 and bytes[2]==0x8d and bytes[3]==0x58 and bytes[4]==0xff then
ldd.address=address
ldd.opcode="lea"
if sender.syntaxhighlighting then
ldd.parameters="{R}ebx{N},[{R}eax{N}-{H}1{N}]"
else
ldd.parameters="ebx,[eax-1]"
end
ldd.description="stupid method to get the address of eax-1"
ldd.bytes={0x67, 0x8d, 0x58, 0xff}
return string.format("%.8x", ldd.address).." - 67 8d 58 ff - "..ldd.opcode.." "..ldd.parameters, ldd.description
else
return nil,nil
end

description: string - The description of this opcode

end

Hey Dark-Byte,I found a bug:
Attach to a process,open a new scan tab (CTRL+T),switch the scan type to 'string',the Caption of the checkboxes 'unicode' and 'Case sensitive' get erased.

Running the latest build 6.4.0.4107, adding the underscore prefix to audio files seems to be causing the same error as before...at least, I assume so because I can't add a custom audio file for enable/disable now.
Thanks.

check that the filenames all are normal english names. Rename them inside the table if you have to
