Types

type Chip8

type Chip8 struct {
	Debug bool

	// CopyRegistersOnShift affects `8XY6` and `8XYE`. If true, the value of VY will be copied into VX before a shift
	// occurs.
	CopyRegistersOnShift bool
	// VariableOffsetRegister affects `BNNN`. If true, `BNNN` will act as `BXNN` and will jump to NNN + VX. Else, `BNNN`
	// will jump to NNN + V0.
	VariableOffsetRegister bool
	// DisableSetFlagOnIrOverflow affects `FX1E`. If true, `FX1E` will not set VF. Else, it will set VF accordingly if
	// the index register "overflows" above 0x0FFF.
	DisableSetFlagOnIrOverflow bool
	// IncrementIndexRegisterOnLoadSave affects `FX55` and `FX65`. If true, the index register will be incremented when
	// loading or saving registers to/from memory. Else, a temporary value will be indexed instead, and the index
	// register will not be changed.
	IncrementIndexRegisterOnLoadSave bool
	// contains filtered or unexported fields
