 Posted: Sat Dec 27, 2014 5:26 pm Post subject: Problem with simple code injection for XP |
 |
|
I reopened Recettear and decided to do a cheat-through. The game compares your adventurer's current XP to its XP table. With XP >= table value and I gain XP, I level up. I started messing with one adventurer for now.
I had no problem with this simple script, assigned to a hotkey:
| Code: |
// Louie
"recettear.exe"+0411068c:
readmem(04510694,4)
|
I use code injection to automate this, but his XP turns into a ridiculous value:
| Code: |
[enable]
alloc(newmem,16)
label(returnhere)
label(originalcode)
label(exit)
alloc(xp,4)
registersymbol(xp)
newmem:
mov [xp],eax
originalcode:
exit:
jmp returnhere
"recettear.exe"+411068C:
jmp newmem
returnhere:
xp:
readmem(04510694,4)
[disable]
dealloc(newmem)
unregistersymbol(xp)
dealloc(xp)
"recettear.exe"+411068C:
readmem(04510694,4)
|
Result:
| Code: |
// actual (bad); 6 bytes changed
0451068C: [E9 6F F9 C7 08 85] 09 00 AC D1 09 00
// desired
0451068C: AC D1 09 00 2C 01 09 00 AC D1 09 00
|
Allocated memory:
| Code: |
0D190000: 89 05 10 00 19 0D E9 86 06 38 F7 00 00 00 00 00
0D190010: AC D1 09 00 00 00 00 00 00 00 00 00 00 00 00 00
|
What's wrong with my script, or what's the best way to go about this? I'm not really good with assembly code, and my current progress comes from skimming the forum and examples.

That is not an injectable spot (code injections only work on code, not data)
you're best off just freezing it to the next address
tip:
add "recettear.exe"+411068C and "recettear.exe"+4110694 to the addresslist named: current and max
freeze current, and then change the value to:
cheat engine will now freeze it to the same value that max has, even when it changes

Edit:
I thought that would work too. It's not working as intended or I did something wrong. His max XP is still changing ahead of his current XP.
I have:
| Code: |
// Address list
[X] Louie EXP 0451068c (aka "recettear.exe"+411068C) 4 Bytes (max)
...
[ ] max 04510694 (aka "recettear.exe"+4110694) 4 Bytes ######
|
And I am still forced to manually update his current XP.
Oddly enough, I tried code injection last night (IT WORKED) and got a character to Lv99 in a few kills. I was half asleep and went to bed reassured I 'saved' something, but that was the game, not the script! FAIL
