i2c crashes

[richardturnnidge]

Querying i2c will cause crash. Screen is left blank with flashing white square cursor.

I appreciate that the PC/Mac will not have any i2c devices, but if running or testing a game that can use an i2c device (eg, nunchuck) the emulator will crash, yet the Agon will run fine and use the hardware.

I have not got deep enough to see if it is when i2c is opened, or if it is when writing to an address.

Maybe an error should be given for the call, not crash. Register A has the error code, it is 0 if all was ok when writing to i2c.

Issue present on emulator 0.9.60 on Mac, running VDP 2.10.1, MOS 2.2.3.
