Ys Seven Cheat Codes

[flamethrower]

I want to make cheats for Ys Seven that change the behavior of the charge attack to be the same as in Celceta and Ys 8.

So far I got to the routine that reads control input at 0x08805DD0. It gets passed the control status word as a1 and the "previous read" control status word gets "passed" as a2. The routine is setting t1...t9 to 0 or 1 (1: pressed) based on the control status word and they only get set if the button is held.

I want to make a 60fps cheat for Ys Seven.
I found 0x8BCF5A8 for the sceDisplayWaitVblankStartMulti parameter (2: 30 fps, 1: 60 fps)
I found 0x08A6A770 for the 0.99 float parameter. Affects game speed. Change to 0.495 for "half speed" (i.e., normal speed at 60FPS). I guess I just gotta make the cheats then.

Usage notes:
Turning off the cheat does not disable it. You must use the "Off" button combination to disable it.

Bugs:
Story / script scenes execute at double speed
Bosses double speed (disable for bosses)

Investigating Felghana cheats:
0x8B49218 sceDisplayWaitVblankStartMulti parameter

I added cheat codes for:

Charge attack charge time

I have worked a bit on the 60 fps patch,character animations on cutscenes and bosses should work at a normal speed now. Camera animation still seems to go at double speed though. I have made them two separate cheats because I don't like really get how you enable/disable them with the buttons.

Good work figuring this out. My 60FPS toggle cheat below should be considered obsolete.

I don't like really get how you enable/disable them with the buttons.

Is it "do not like" or "do not understand"?

More like do not understand, will I ever learn to speak English properly...

Look here under Miscellaneous Code Types: Joker Code: http://raing3.gshi.org/psp-utilities/page/PSP/CodeTypes
Also look under Button Activators

Great find, I never managed to find proper documentation on CwCheat, I had no idea you could do that stuff. I had no clue what that 2 at the start of the cheat code did, since yours did it I went along with it.

This was similar to Celceta's ,but not exactly the same. Hopefully getting something like this on Nayuta,Ys vs Sora and Brandish shouldn't be too hard once we get this fully working.

Awesome, I broke phpBB again.

Those are the generic "cw" codes for constant write.
0 says write byte
1 says write halfword
2 says write word
This one:

_L 0x203CF5A8 0x00000002

Well, we only need to write a byte, but the rest of this word is unused by the game so it's just easier if we write a word.
