It seems button combos reside between 81C9D8 - 81CD3E. Some may be shared. I haven't quite decoded it yet, but I believe they are backwards, and those combos that end with High Kick combos start with 38.

They seem to start with a big number, then continue with #s 5-8. I believe a 00 byte marks the beg/end of the combo.

0000 - HP
0001 - LP
0002 - BL
0003 - HK
0004 - LK
0005 - Up
0006 - Down
0007 - Back
0008 - Forward

It's not quite as simple as it seems, but I thought I'd share the info for those that might want to mess with this. For Example, Liu Kang's dragon fatality combo is at 81CA8E (38 07 07 08 06 00 (backwards is D,F,B,B,HK)). The code 81CA9000 (DDAB-CDD1) Would cut this combo short, making the fatality easier by just making it B,HK. So...

Make Liu Kang's Dragon Fatality Easier (Back, High Kick)
DDAB-CDD1

I tried cutting the combo to just the High Kick button, no dice.

I would assume the values loaded between the address range initially get loaded there based on a read from the character selected address at some point so yes they are most likely shared between characters and just loaded when needed. With that being said you could make custom move button combinations for each move in the game if you wished which is great (Very helpful for moves that you would have to charge all round like Shang Tsung's Kintaro fatality).

When the compare is met on these combinations they should write a value to the move modifier address (which I am after ). I may look into this tomorrow when I have time after work.

The combo buttons, one at a time, are read at 81C8FA, and stored at 00182E, and then compared to the button presses at 81C90B.

Nice; I love it when hacking takes the form of research. This information will likely prove useful for later codes, as well.

[Hybrid]

Thanks for the updated code. Btw do you mind me asking how you found the routine? When I tried a while back I looked for what was checking the button input at the end of the initial screen, however due to lack of time I never pursued it.

Thanks for the explanation! How did you come up with the value 30 or is that L + R value held? Very nice hack there Hybrid for Jade verified working in v1.0/v1.1.

[Hybrid]

dunno really just used a diffrent than search untill i narrowed it down to a few codes and tested it out untill i got the right one

[Abystus]

Dan Forden (Toasty) on Every Uppercut (Also has side effect of Jade Clues before every round on/after the 5th opponent.)

81DECA80
80FF3E80
80FF3F05

Works in v1.1.

[Abystus]

In the above Dan Forden (Toasty) codes there is a side effect which will start Jade clues on/after the 5th CPU opponent. The first code is to nullify the use of a different Toasty routine if on the portal stage as they make it harder for him to come out during play on that stage (If this code is not included Toasty will use a separate routine and will not appear even if you are using the 2 following codes). I have noticed side effect is to do with the 2nd + 3rd codes on/after the 5th opponent. This change in behavior I assume is based on something in the CPU difficulty routine changing. Toasty will still be enabled, however you will always get the same clue ("I am called Jade.") from Jade before each round start not present before that point. It may have something to do with a flag not being set due to the way it's being compared. If anyone would like to lend a hand in resolving the issue and possibly pulling the side effect out as a separate code (Secret Character Clues Every Round) it would be appreciated.
