 |

There is a bug in CE, after the target process is attached and then registered a assembly custom value type ,
the value cannot be read and written correctly.
Haven't tried 7.3。But it doesn’t seem to be in the repair list。

Check your custom type. Does it properly implement both read AND writes?
Also, keep in mind the custom types run inside CE , NOT inside the target process

The same script, first open the script, then attaching the game ,it is correct.
When attaching the game first and then loading the same script, it is wrong.
The author said it was a bug in ce .
| Code: |
if not ARCGameEngine then
ARCGameEngine = registerCustomTypeAutoAssembler([[
alloc(TypeName, 14)
alloc(UsesFloat, 1)
alloc(CallMethod, 1)
alloc(ConvertRoutine, 16)
alloc(ConvertBackRoutine, 20)
alloc(ByteSize, 4)
alloc(AGEBitsMasker, 4)
alloc(PreferedAlignment, 4)
registerSymbol(AGEBitsMasker)
TypeName:
db 'ARCGameEngine', 00
CallMethod:
db #1
ConvertRoutine:
[32-bit]
mov ecx, [rsp+04]
[/32-bit]
mov eax, [rcx]
xor eax, [AGEBitsMasker]
ror eax, 0E
ret
ConvertBackRoutine:
[32-bit]
mov ecx, [rsp+04]
mov eax, [rsp+0C]
[/32-bit]
rol ecx, 0E
xor ecx, [AGEBitsMasker]
[64-bit]
db 41
[/64-bit]
mov [rax], ecx
ret
ByteSize:
dd #4
PreferedAlignment:
dd #-1
]])
if ARCGameEngine then
for i = MainForm.VarType.Items.Count - 1, 0, -1 do
if MainForm.VarType.Items[i] == ARCGameEngine.name then
MainForm.VarType.ItemIndex = i
if MainForm.VarType.OnChange then
MainForm.VarType:OnChange()
end
break
end
end
end
end
function MainForm.OnProcessOpened(pid, handle, caption)
if process == "AGE.EXE" then
local COMethod = readPointer(readPointer(executeCodeEx(0, nil, "AGE!GetClassObject", "AGE:IAGEService")) + 0x0C)
local isModern = readBytes(COMethod, 1) == 0xE9 and 8 or 0
if isModern ~= 0 then
COMethod = COMethod + 5 + readInteger(COMethod + 1, true)
end
local baseAddr = readPointer(readInteger(COMethod + 1)) + readInteger(COMethod + 7, true)
local isLatest = readPointer(baseAddr + 0x24) ~= getAddress("kernel32.dll") and 12 or 0
local startAddress = readPointer(baseAddr - 0x1470 + isModern)
local stopAddress = startAddress + readInteger(baseAddr - 0x1488 + isModern) * 4
unregisterSymbol("COM3")
registerSymbol("COM3", startAddress)
unregisterSymbol("AUX")
registerSymbol("AUX", baseAddr + 0x20 + isLatest)
MaskValue = readInteger("AUX")
writeIntegerLocal("AGEBitsMasker", MaskValue)
MainForm.FromAddress.Text = ("%08X"):format(startAddress)
MainForm.ToAddress.Text = ("%08X"):format(stopAddress)
function AddressList.OnAddressChange(list, row)
if row.Type == vtCustom then
local addr = row.Address
if '0' <= addr and addr <= '9' then
local curr = row.CurrentAddress
if startAddress <= curr and curr < stopAddress then
row.Address = ("COM3+%06X"):format(curr - startAddress)
end
end
end
end
AddressList.OnDescriptionChange = AddressList.OnAddressChange
AddressList.OnValueChange = AddressList.OnAddressChange
end
end
openProcess(getWindowProcessID(findWindow(utf8ToAnsi("ARCGameEngine"), nil)))

I don't have this game so I can't check, but I assume it goes wrong at the setting of AGEBitsMasker in "function MainForm.OnProcessOpened(pid, handle, caption)"
Can you add some debug info there to see why the mask you set is not what it should be
(Also, don't run this script more than once)

The script is downloaded from here, made by sceawung
necocan-index.rick-addison.com/bbs/patio.cgi?read=64&ukey=1
Difficult to read Japanese with Google Translate.
the author sceawung does not seem to explain what he wrote.
What does this lua mean, maybe only the sceawung knows。
Most users of this website don’t even know ce.
