Description

Game Name?

Advance Game Port - GNHE5d
Action Replay by Datel - DTLX01 (Modified to DTLE01 for Dolphin to run it)
Maxplay - GNHE5d
Max Drive Pro v1.0 - GNHE5d

Yes I know several of the discs are the same ID; that's just how they are.

What's the problem? Describe what went wrong in few words.

Single core will immediately (within 2 seconds) luck up in all of them except the advance game port, which will freeze up 2 seconds after launching a GBA game. Dualcore will randomly hang. Can last 5 - 10 minutes, can last 2 seconds. It will hang, just a matter of when.

What did you expect to happen instead?

I didn't expect these discs to work at all honestly. It was a pleasant surprise.

What steps will reproduce the problem?
1.Make sure you have a bios enabled.
2.Make sure you have LLE audio enabled
3.Boot a disc in single core, it will crash.
4.Boot it in Dualcore, it will crash /eventually/

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

4.0, 4.0-5378

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

Nopers

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Core i5 3570K, GTX 760, Windows 7 x64

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Fiora (Queen Fiora? Jit Princess Fiora? JMC's savior Fiora?) actually found a workaround for this bug already. in void SetFinish, modify line 310 from

CoreTiming::ScheduleEvent_Threadsafe(0, et_SetFinishOnMainThread, 0);

to

CoreTiming::ScheduleEvent_Threadsafe(250000, et_SetFinishOnMainThread, 0);

That completely eliminates hangs. It can still rarely hang with 200000. We don't think this is the correct solution, but it is at least a start toward understanding it.

History

#1 Updated by kolano over 3 years ago

Just did some retesting with Maxplay in 5.0-6004, which is likely of interest.

With Dual Core just a single "FIFO is overflowed by GatherPipe ! CPU thread is too fast!" error occurs. With Single Core the error now happens numerous times, until a separate Unknown Opcode error occurs. The top part of the first screen then starts to show and when Dolphin hangs without further error, only showing the top 20% or so of the screen.
