PPSSPP crashes at launch
Hi,

I'm unable to use PPSSPP: when I execute it it justs quits, without any error message, before even drawing a window. I've downloaded it and the c++ redistributables again and it still won't run.
I've checked the windows event log and there's nothing wrong there.

I have Windows XP64, graphic card is radeon HD4870 with emu_crt drivers configured to send a 15kHz video signal, desktop resolution is 640x480.
Is any of this incompatible with PPSSPP? (it works fine on another computer with win7)

What could cause this problem?

Thanks!

I... Are you serious about those specs? Or was it meant as a joke post?
Because it sounds like you are installing it on arcade cabinet?

Technically it should run, but I dont know if PPSSPP is still compatible with WinXP, not to mention XP64.

RE: PPSSPP crashes at launch
XP64 might run, but only 32 bit version of PPSSPP(if it even comes with WOW64 emulator). AMD64 version of PPSSPP isn't and will never be supported on this outdated OS and trying to use it is probably your problem;p.

Also for radeon HD4870 no idea about any driver mods and their weirdness, but most official drivers will not run in OGL well. It might run better with old 11.11a or alike drivers, otherwise you might need to use less compatible D3d9 backend.

Well yes I'm serious and you're correct, the PC is used as an arcade cabinet. I have some emulators installed and working fine on it, and I wanted to add PPSSPP.
I know that's not a common config, I'm wondering if there's something there that's incompatible with PPSSPP. Or maybe I'm juste missing some dlls or something.

Yes with the 64bit version I have an error message saying it's not compatible with my OS, which I get.
The 32 bit version is the one that crashes without saying anything.

RE: PPSSPP crashes at launch
Then as mentioned earlier it might be graphics driver. You can try editing ppsspp.ini and change GPUBackend from 0 to 1, or switching at your other pc and copy the file if it crashes before creating one.

There are no open source windows drivers so it's just some hackish mod which might as well be tailored for one app breaking stuff for all ppsspp backends. But also XP64 was always known to be awful when it comes to compatibility and there had to be a reason for that, it's WOW64 might simply be buggy meaning you're out of luck on that system.

If you can't change OS on that pc, you could still use some linux distro from pendrive to avoid mixing modern software with OS that remembers dinosaurs.

RE: PPSSPP crashes at launch
Problem solved: it turns out the culprit is a USB hub! Apprently it causes some sort of problem with directinput, and that makes ppsspp crash. I just need to unplug it when I want to run ppsspp.
Thanks!

RE: PPSSPP crashes at launch
Well that's definitely weird problem, even if it wouldn't be PPSSPP fault, would still be nice to handle it differently than crashing.

Does it happen while using hub on any newer windows or other OS? Might be worth opening a new issue on git for it. But if it only happens with XP it might be hard to find the problem. Don't even have a hub to test myself and no idea what difference it would make on dinput stuff.

Technically a hub should make 0 difference. Unless it is somehow broken or the drivers are broken. Even then it should not make the emulator instacrash.

Right? Weirdest part is, I don't think it's defective, it's brand new and the devices plugged in it work. It just makes this particular software crash.

I've just tested it on Win 7 and ppsspp runs fine with the hub connected.
