IOS < 6.1 JB Ipad4 screen flashes and reboots when pcsx_rearmed core is loaded

[jack4455667788]

I and several others have been having an issue where even attempting to load the core on JB 6.0 ipad4 causes the screen to flash briefly, and reboot the device. Other emulators that reportedly require JIT to function work without issue (PPSSPP, and the NDS4IOS). Is there some special build required for 6.0? Please tell me there is!!

I wish I didn't have to do this! Apparently I caused this issue myself when I chose to stay put at 6.0 jailbroken (as users in 6.1.2 even on the ipad4 do not have this issue)

Assuming you respond as I expect you will (that there is nothing you can do to test or resolve because you yourself are at 6.1.2 and it's working there), is there anything I could try/do to help the process? I have already searched for log files, but it appears the crash is so instantaneously severe that none are made. I would love to capture a crash report for you (if that would help)... Where should I look for instructions on how to accomplish that (keeping in mind that I only have a snow lepoard hackintosh at my disposal currently).

I will do whatever possible to get this working, please give me orders! In any case, thank you so much for your hard work!! From what I have read, your pcsx_rearmed rocks! (and I am dying to try it myself)

It really sounds to me like a bug in jailbreak code or in iOS itself, as an app shouldn't be able to reboot the device no matter what it does. Maybe jailbreak developers could be found somehow and pointed to this problem, they could have some ideas as it's jailbreak that patches the kernel to enable JITs to work at all.

Have you tried running 32X games on PicoDrive core? It shares OS related code with PCSX, it having the same problem (or not) would give a few pointers.

[jack4455667788]

I have confirmed that 32X games work without issue (sorry it took so long, I had some permissions issues).

I am not sure if it will help or not, but it seems someone was able to collect a crash report on an iphone 5 regarding this issue. http://pastebin.com/3y7HzzFd

The guys on this russian forum seem convinced that anyone on less than 6.1 will experience this problem, but I have no idea why they think that, or why that might help you.... http://translate.google.ru/translate?hl=ru&sl=auto&tl=en&u=http%3A%2F%2F4pda.ru%2Fforum%2Findex.php%3Fshowtopic%3D467347%26st%3D160)

Anyway, thanks for the response (and other hard work), and please let me know if there is anything at all I can do to help!!

[notaz]

That crash report is just from non-jailbroken device.

Do you get anything in /User/Documents/pcsxr.log ?
(the location might be wrong, I don't have any iOS devices and developed this thing blind with Squarepusher doing testing, and he was getting that log somehow).

I too have the same issue trying to load .bin file downloaded off the internet with pcsx rearmed core.

I'm on Iphone 5 6.0.2 with evasi0n jb.

No log created from the core, diagnostic & usage shows kernel panics:

Not sure if it helps.

The log seems to be truncated, can you put it on some pastebin or somewhere?

[denOpik]

Here it is:

It's still truncated after the "thre" part. If iOS itself saves it like that then too bad, there is no useful information there.

[jack4455667788]

This is in no way a solution to this issue, but thanks to notaz adding the dynarec switch, and meancoot compiling and uploading the interpreter (non-dynarec) module, there is now a workaround to this issue. I havent fooled around much with it yet, but it works for me with sound and seems close to full speed.

Above is meancoots compiled version of retroarch, I extracted the entire ipa file and used the full executable. Then I manually selected the core "pcsx_rearmed_interpreter_ios.dylib" and selected the image file. Thanks!!

JB problems from 2014 are unlikely relevant any more, closing.
