Install deb -> CS_DEBUGGED is not opened -> Use syscall to use JIT Install deb -> CS_DEBUGGED is opened -> Use Cydia Substrate to use JIT Install ipa by using AppSync -> CS_DEBUGGED is not opened -> Use syscall to use JIT Install ipa by using AppSync -> CS_DEBUGGED is opened -> Use Cydia Substrate to use JIT Install ipa by using impactor -> on iOS11 -> Use syscall to use JIT Install ipa by using impactor -> not on iOS11 -> Can't use JIT Therefore, the best practice is to use the jailbreak tool that enables CS_DEBUGGED to jailbreak so that PPSSPP can enable JIT directly by calling Cydia Substrate. While this can be a problem for players who use syscall to call JIT, this has no effect on players who use Cydia Substrate to call JIT. You can just use the latest xcode command line tools to build everything. It means build "a better compatibility version". (It is important to note that this can only reduce the frequency of such problems, but not really solve the problem). So we need to use iOS11 sdk and cmake to build PPSSPP xcode project. When using cmake to build PPSSPP xcode project with iOS12 sdk, since the iOS12 SDK will add strange assertion code to the project, this will result in more frequent exit freezing. (There have a bug in iOS11 which allowed you to simulate the xcode debug state without the get-task-allow entitlement, so you can still enable JIT).Įven if you successfully use the system call to enable JIT, sometimes for some reason, iOS will always wait for signals from Xcode. ![]() First, even if we call syscall in the code, if you use opactor to install ipa (whether or not you jailbreak), the get-task-allow entitlement in the PPSSPP main program will be destroyed - you will not be able to use JIT. We using syscall makes the system think "app is being debugged by xcode", so that players can use JIT even if they don't connect to the computer. Yes, so we need to fake a state and let the system think that "app is being debugged by xcode" In order to make it easier for developers to debug their applications, Apple will open up some additional functions for apps that are being debugged by xcode (even if they should not be used in the released app in their plan), which includes JIT! Yes, this is exactly what we need!īut it is impossible for every player to use PPSSPP with a computer? No :P ,in fact, we have two ways to get around this limitation of Apple. This is to protect the iOS system from malware, so Apple filters Some "safe and reliable" APIs are available for users/developers to call, and this includes JIT. Some function can't even be called at all (Like Task_for_pid_0? :P). It sounds pretty good? But what's wrong with this?ĭue to its closed nature, the iOS system is not allowed us directly called some function when we want to call. Among them, Dynarec (JIT) mode is the most efficient and can get better simulation results. PPSSPP has three cpu cores to simulate psp and run our game - interpreter Dynarec (JIT) IR interpreter. ![]() What means "a better compatibility version"? ![]()
