Raw addresses found in Um Jammer Lammy NTSC-U. Pretty much compatible with 32-bit emulators such as ePSXe, Mednafen, or the 32-bit version of Retroarch. Includes things like score gains, timed inputs, internal rapping values, and CPU line editing (though it's largely incomplete and most of the addresses in Co-op need fixing).
This cheat table will not work unless you offset all addresses by your PSX emulator's memory map. Emulators with non-static addresses (e.g. DuckStation and other 64-bit emulators) are much trickier to set up.
No knowledge of coding is necessary; just download or clone this project and load the cheat table with Cheat Engine. Cloning is highly recommended as you'll get the latest additions as soon as they come.
