Original GitHub issue: https://github.com/hrydgard/ppsspp/issues/4888

As soon as we enter the Tunnel, the ppsspp crashes. Crash happens in Windows 32bit, Linux SDL and Qt versions.

As per this post, version 0.9.1 did not crash but crashes in later versions.

Kindly look into the issue, it's a fun action game.

Actual PSP gameplay:

Does it still crash if you turn on "Low quality spline/bezier curves"? (yes, I know that the graphics will be semi-broken).

If it doesn't crash with that setting on, the crash is obviously in the spline/bezier code.

Yes, it still crashes with Low quality spline/bezier curves enabled. Tested with Qt version.

v0.9.1-134-g554ca84 does not crash, as in the git biset wiki,

should I go 100 commits up, till i get a crash?

ok i'm going backwards from the current 0.9.6

git checkout master

should take you back to the start. Or you can find the commit hash in the commit list here and just do

git checkout fa83042

or whatever.

Or use "git bisect", read up on it, it's pretty easy.

Does this still happen? There have been some improvements in the bezier code.

What if you try the "medium" or "low" bezier quality? Atlhough that's not a solution if it still crashes.

I checked that this issue crash on this address(0x08AFBDF8).
Using @daniel229's savestate.
It seems related to bezier, but I think it's not bezier issue. I guess it's broken opcode issue.
As I thought, this issue seems very similar to this.
Tantei Jinguji Saburo will crash at open the inventory (I'll report this issue later)

We need more research about these issues.

For the Tantei Jinguji Saburo,it won't crash if replace the jpn0.pgf with other font file like the one from PSP.

Really? Thanks for useful information. I'll try to replace font file.

Well, I tested this game issue avoid bezier 1x7 like this

void TransformDrawEngine::SubmitBezier(void* control_points, void* indices, int count_u, int count_v, GEPatchPrimType prim_type, u32 vertType) {
    Flush();

    if (count_u == 1 || count_v == 1)
        return;
....

It's no problem about play the game...
So, probably bezier issue...
But 1x7 bezier is what? curved line? not curved surface...
Does PSP support curved line? If so we need support it.

It seems from my testing that 1x7 and similar doesn't draw anything.

Does this game still work fine without crashing with the latest code? Any visible graphical issues? If it's working, I think we're safe to close this.
