Fix

The GPU-specific PACK and UNPACK instructions share opcode 63. PACK is chosen by encoding '0' in the source operand, and UNPACK is chosen by encoding '1' in the source operand. RMAC had the magic source operand values reversed.

Test case demonstrating the bug

Attaching a trivial test case. The screen will be yellow when it's working, red when it's not.
