Add Zettai Zetsumei Toshi 3 bypass for softlock

[LunaMoo]

Fixes #4901

I couldn't figure out the actual issue, pretty sure it's timing issue of some sort as the problem happens on PS3 following it's compatibility list.

Trying to push this fix as the game might become very popular in the next few days due to english translation releasing this month and while I shared a workaround for it already, I think having it playable out of the box would be a better experience for typical user using an emulator just because english translation.

That's quite an icky little hack :/

But, it indeed would be nice to have it working on 1.13 with a translation coming out... Hm hm. That it also happens on the PS3 port is quite curious indeed...

Turns out they released less than an hour from me opening this and they included the workaround patch within the translation, so it's not a big deal anymore. BTW seems in addition to PS3, this is also a problem of PSV.

Still, original versions of the game will be broken without this, the function this workaround patches is only ever used at character select screen and my guess is it expects something to happen before it gives player control, this never happens or more likely happens earlier and that's why it's softlocked. Once the parameter is passed once the game will never again use that code until starting a new game again so it's safe and tested as I had my own "ingrish" translation years ago running with this workaround.

Edit: They also use exact patch I posted to deal with this problem(noping a branch) so english patched version wouldn't even have the code from here applied due to hash missmatch.

From the page on gbatemp for the translation:

• Built-in patch that fixes a bug present in PPSSPP and Adrenaline where the player cannot select a character

So this also happens n Adrenaline as well.
Reminds me of Resistance Retribution which also got a similar freeze/crash bug on both PPSSPP and Adrenaline.

There's really no similarity between those games other than the fact that even official Sony's emulators can't get the timing same and some badly coded games suffer from it. RR just bugs out and crashes, ZZT3 expects something which doesn't happen outside of the real console.

From my injection of english translation into ZZT3 years ago seeing how they tried to be tricky about blocking(delaying) modifications to the game disc, that softlock at character select screen might just be another intentional anti-warez feature.

I also had a theory that RR expects something too , in this case it expects USB to work.
That's because the game always expects or seems to check if the PSP is connected to PS3 for some bonus content.
The game always checks/polls it for the infection mode.
Which may be related to why it crashes or bugs out on emulators (Adrenaline also cant emulate the PSP's USB properly).

The game also checks the AV output as well (I think it's the only game that does it) to let you control the game with a dualshock 3 controller.
And well , that feature does not work on a Vita ...
