CL-LiveDebug joker address

[nonijod]

I tried using CL-LD and while it work very nicely in some games, in others the autodetect doesn't find the joker address. What (and where) should I be looking for if I have to specify it myself? I had a quick look at some autodetected addresses from different games and looked them up in a ramdump but couldn't find what they had in common and looking for a guide also didn't yield any results.

Sometimes nearby joker addresses is a string of bytes that are identical between many games. Most jokers found are in the reverse format of "FFFF" that you treat like an unsigned value that you take the combination of button bits and subtract from it. Rarely you'll see it not in reverse format where you'll just add the button bits to 0000, one of the Tekken games had one even though it also had it in reverse format somewhere in memory too. I don't remember the button values anymore because it's been over 5 years, but they seemed to be the same for every single PS2 game.

I think what you've described are joker commands, not a joker address. However it helped me find the 2 ways how to get the address (http://gamehacking.org/vb/threads/1586-PS2-Joker-Commands). In regard to that, while looking for the address with the second method how far is safe to look for the addiu with register a2 and still be sure that it belongs to the pad? With the first method the only label I found was Padinfo and using that address+2 didn't affect the game at all. The DXXXXXXX address I found in use in some cheat freezes the CL-LD upon pressing Play Game (or something along those lines), doesn't even show the debug colors. However it works as expected with cheat devices like modded CodeBreaker.

LiveDebug isn't a cheat device, and will not accept that as a "joker". 0xD0000000 isn't a valid mapped memory address on the PS2 which is why it will freeze every time you attempt it. Remove the 0xD from the address and try again.

Oh yeah, the tut was working with addresses starting with D and I didn't realize it's a command and not a part of the address. Will try without it.

edit: Well, the IOP halts and won't let me get past the failsafe mode screen (which is stretched - http://s17.postimg.org/a21hypcxb/20160331_201621.jpg ) so I suppose that I'm still stuck with Cheat Engine and PCSX2 for some games. Kermit also looks interesting for this kind of job.
