STP-Opcode crashes EmuHawk (Or the SNES core) #305

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
By experimenting i found out that, at least on the SNES, the STP-Opcode crashes 
the emulator entirely.

- What steps will reproduce the problem?
1. Run the Opcode STP. See below for example ROM wich runs the Opcode at Frame 
60.
2. Crash

- What is the expected output? What do you see instead?
I though it just doesn't emulate the CPU anymore, or whatever the behavior on 
the real SNES would be. Maybe even a message like "The CPU was halted." 
Instead i am getting "no response"/a crash.

Using the example ROM, in "Compatibility"-Core it crashes at Frame 60 and on 
the "Perfomance"-Core it crashes at Frame 61.

- What version of the product are you using? On what operating system?
Windows 7 Home Premium 64-Bit(s)
BizHawk 1.8.4, BizHawk r8158

- Please provide any additional information below.

Um what? The ROM i provided is a custom/self made one.
I am just reporting that the Emulator crashes at the STP Command.
It even happens in other games, like Super Mario World if glitching.

I thought you were only talking about the ROM itself causing problems and not 
the STP command itself.  The STP command is a problem and has been confirmed.
