Hello, i want to hack but i cant set a negative value. My purpose is to set a number like -99999 when buying an item, so that I can get the positive balance when the server executes. But when I set a negative number, it does not accept and jumps to another positive number. I also tried putting 1-99999 but still not. What should I do?

This will help explain it: https://wiki.cheatengine.org/index.php?title=Tutorials:Value_types

Try right clicking the address and selecting "show as signed".

-99999 (signed) == 0xFFFE7961 (hex) == 4294867297 (unsigned)

Positive numbers can be mapped to negative numbers via certain operations.

Under two's compliment, the 4-byte values -99,999 and 4,294,867,297 have the same bit representation in memory. The only difference between them is conceptual: one is unsigned while the other is signed.

Right click a memory record in the address list and select "Show as signed" to interpret an integral value type as signed.

If the game itself is treating the value as unsigned, you're likely SOL.

Thanks, yes it show 4294867297, when i choice "show as signed" and set -99999, it work. But the app cant handle. It seems the value is still 4294867297, is a big number and I can not buy it. if i set to 0, it working.

the game itself doesn't handle negative values for the price. (It's an unsigned integer)
you meed to reprogram the game to be able to deal with negatives
