Description

Game Name?

Game ID? (right click the game in the game list, Properties, Info tab)

N/A

MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)

N/A

What's the problem? Describe what went wrong.

Dolphin takes at least 641 milliseconds to reload the emulated IOS (GetESBootTicks in ES.cpp) but libogc only waits 400 milliseconds (__IOS_LaunchNewIOS in ios.c).

What steps will reproduce the problem?

Launch an app that performs IPC synchronously like TinyLoad from the OHBC. At some point it will receive an unexpected ack and get stuck.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes 5.0-16545.

Is the issue present in the latest stable version?

Presumably.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

N/A

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

N/A

What are your PC specifications? (CPU, GPU, Operating System, more)

Intel Core i7-8650U, Intel UHD Graphics 620, Arch Linux

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

N/A
