Hello! So I was messing around with Kingdom Hearts: Chain of Memories, a GBA game, in emulator and wanted to try my hand at making cheats. So I looked at some pre-existing ones for some guidance and noticed that all of them modified the System Bus (and that tbe built-in Cheats tool defaulted to the System Bus). Yet when I tried to use RAM search to search through the System Bus, I found it was greyed-out and that I couldn't access it. I'm a complete beginner with this stuff, so any help is useful.[/list]

System bus is 32 bits. It could not be searched usefully, it's too much data. That's probably why. You need to search individual ram banks and then read a GBA memory map document to see where in the system bus they are mounted. For example if you find a value at 0x000C of IWRAM then since IWRAM is mounted at 0x03000000, your system bus address would be 0x0300000C
