Problem with frame skipping and custom resolution
Not sure if those problem are related only to this game(because they are related to ppsspp features),that's why I didn't posted in the game thread.

1.
The game is Hexyz Force and if frame skipping is enabled(any mode),ppsspp will crash after you load the save and the game continues(after the loading screen)

The text is also missing in that cut scene(first message)

The game seems to have a lot of problems in the Levant storyline and none in Cecilia(good thing I played her story first)

The problem rev is 0.8.1-1378 x86
It's ok on 1377

2.
There is also something wrong with setting custom resolution(2x).
It happens at random...one of those things may happen or all of them.
1.The screen will start flashing really fast
2.Suddenly textures disappear(including the mini map)
3.Will show weird textures

To fix the problem I have to somehow force a refresh...for example exit=>enter full screen or bring the pause screen menu(Esc) and then resume the game.

The problem is not related to the recent mini map fix,it happens only if I use 2x resolution(which actually gives me more speed in games that need buffered rendering)

Here is a save for the first problem
I'm currently using 0.9.1-1302 x86

RE: Problem with frame skipping and custom resolution
I just tested this with 0.9.1-1378 windows x64 and I encountered none of those issues with it other than slight flickering on the save/load screen with frame skipping enabled.

RE: Problem with frame skipping and custom resolution
It's still the same here on 0.9.1-1378 but x86
I just downloaded that rev,extracted the archive,set the frame skipping to auto and directly start the game...it crashed again.

Can you try the x86 version

RE: Problem with frame skipping and custom resolution
I have to echo mr.chya's findings.

I'm not seeing any of those issues on 0.9.1-1378 (either 32 or 64 bit) using Frameskipping or 2x forced Rendering Resolution, EXCEPT for the screen flickering when Frameskipping is set to any number higher than Auto (game won't skip frames on Auto for me since my rig can handle it at 100%)

Tested scenarios:-

1. Using frameskipping and booting the game = Doesn't crash, just causes the game to flicker for any setting above Auto.

2. Using 2x rendering resolution (just this change) = No screen flashes, minimap still behaves and the textures still look normal to me.

Tested using rig in sig and orphis builds.

PPSSPP Modern Testbed:-
Intel Core i5 4690K @ 4.0 GHz
NVIDIA Geforce GTX 760 2GB GDDR5 VRAM @ 1138/6500 Mhz
16 GB DDR3 RAM @ 1600 MHz
Windows 7 x64 SP1

PPSSPP Ancient Testing Rig:-
Intel Core 2 Duo T9550 @ 2.8GHz
ATI Mobility Radeon 4670 1GB GDDR3 VRAM @ 843/882 MHz
8 GB DDR3 RAM @ 1066 MHz
Windows 7 x64 SP1

RE: Problem with frame skipping and custom resolution
One other thing I found is if I set the frame skipping to some value(not auto...or I'm at a place that auto is skipping frames),using Emulation=>Stop will crash the emulator

It is also crashing if I disable the frame skipping,load the save and when the 3 characters appear(without pressing X to continue)if I press F7 to switch to 1-8 frame skipping mode,ppsspp will crash immediately

Or if FrameSkipUnthrottle is set to true,frame skipping to off and you press tab there

PS.You are not running the game in Unlimited speed with FrameSkipUnthrottle set to "false" right?
