Random encounter subroutine reversed…now to make a script that tells me exactly how many more steps until an encounter occurs :).

Alright, not to get too off topic here, so last post about FF4.

I can now predict what the next monster group will be…not gonna explain it this time because I’m lazy but if anyone is interested themselves, the value for the monsters is stored at 0x7E1800. It’s rather long on how it works but kinda simple. Anyways, the end result is at 008A16: STA $1800. Basically I did everything the assembler does ahead of time so I can predict which group is next.

Translated the encounter group portions to lua and wallah:



local function enemygroup()
    local group = 0
    local x = 0
    local x2 = 0
    local val1 = 0
    local val2 = 0
    local val3 = 0

    val1 = bit.band(bit.rshift(memory.readbyte(0x7E1707),2), 0xF8)
    x = (bit.rshift(memory.readbyte(0x7E1706),5) + val1)  % 0x100
    val2 = bit.lshift(memory.readbyte(0x0ec542+x),3)
    x2 = memory.readbyte(0x7E0687)
    val3 = (memory.readbyte(0x14ee00+x2) + memory.readbyte(0x7E17EE)) % 0x100

    if val3 > 0xFC  then
        val2 = val2 + 7
    elseif val3 > 0xEC then
        val2 = val2 + 6
    elseif val3 > 0xCC then
        val2 = val2 + 5
    elseif val3 > 0xAC then
        val2 = val2 + 4
    elseif val3 > 0x81 then
        val2 = val2 + 3
    elseif val3 > 0x56 then
        val2 = val2 + 2
    elseif val3 > 0x2B then
        val2 = val2 + 1
    end
    group =memory.readbyte(0x0ec796+val2)

    return group

end

So anyways, like I said, last post about FF2. I’ll be posting updates on my youtube channel if you’re interested in this.

163

About using the HUD with mame to train : what speed should one use to have the timings be as close as possible to the arcade ? I know that with ggpo it would be 0 or 1, but when training with an emulator offline, I have no idea.

164

MAME is a lot more accurate than Final Burn Alpha, so the emulation on mame-rr will be a lot closer to the arcade than fba-rr. I just use the default speed settings in mame-rr.

165

I went to the arcade after doing some training with mame, and I noticed that it was slightly slower. The giveaway was the timing to chain two stand lk’s when doing dic’s crossup combo (I did it too quickly so only one lk would come out). Turbo 1 seems the closest (for the world/us version : arcade t2 = mame t1).

166

This game has been broken… omg…

Good job…

Also, I feel the love in this thread bros, ST is the greatest:rock:

167

Pasky, make ST to run in actual speed 0, I mean, ST basically is a patch of The New Challengers :wonder:

168

Dammit has already done that for the Frame data collector.

169

how many of u guys did know Pasky didnt make it all by himself? shame of u Pasky! well, I guess imitation is the best form of flattery, n a couple of irony pics:

LOL, You’re fucken stupid.

:arazz::rofl:

172

You didn’t troll anyone but yourself…:rofl:

173

Blame my macro trollin button then :eek:

174

Ok, I’m too lazy to reverse damage because it takes a lot of tracing, eventually I will. I got the subroutine breakpoint address if anyone else wants to do it (the behind a round damage), not that I can’t, I just really don’t feel like it.

Is there anything anyone wants to have figured out that remains a mystery that doesn’t involve some video a top player did that gives me nothing to work with :P.

175

Yes, there are more mystery to solve.

I’m working on a idiot’s safe jump guide.

One thing we all know is that the opponent will wake up faster when knockdown in the corner.

Is that a constant factor or does it varies based on the distance to the corner or maybe something else?

(Another remotely related issue is ken’s knee bash loop (and other holds) vs opponent wake up time)

176

Oh like how far they jump off the ground when they come out of grabs? I always found that annoying because sometimes I wanna blanka ball behind them after a head bite in the corner for mixup but sometimes they fall quick, I’ll look into that.

177

Yeah that’s interesting too but what I described above is the number of frames needed for the opponent to get up after a knockdown.

Outside of the corner it’s a constant number of frames. When they are bounced off the corner during the knockdown, they get up faster. Which makes the safe jump timing much more difficult because you have to adjust it on the fly.

178

Show me a video so I know what to look for, I never noticed this.

179

never? LOL u noob

180

I seriously didn’t notice it. :stuck_out_tongue:

I know sometimes chars just wake up differently depending on what they get hit with, I had no idea a corner knockdown was always a quicker rise. I just thought it was random throughout the stage.
