		+	== Appendix ==
		+	=== Programmable processor and emulation ===
		+	Here is a pseudo code in C to handle NEO mappers extension for programmable processor based cartridges or for emulators:
		+
		+	NEO-16 mapper:
		+	<syntaxhighlight lang="c">
		+	const uint8* romData; // ROM data
		+	uint16 bankValue[3]; // Bank switching register value
		+
		+	// Extended function prototypes
		+	typedef void (*funcEnable_t)(bool, uint8);

		+	// Extended functions table

		+	funcRead_t funcReadTable[3];
		+
		+	// Handle device initialization
		+	void NEO16_Init()
		+	{
		+	for (uint8 i = 0; i < 3; i++)
		+	{
		+	bankValue[i] = 0x0000;
		+	funcWriteTable[i] = NULL;
		+	funcReadTable[i] = NULL;
		+	}
		+	for (uint8 i = 0; i < 32; i++)
		+	funcTab[i] = NULL;
		+	}
		+
		+	// Handle write access
		+	void NEO16_Write(uint16 address, uint8 value)
		+	{

		+	if (bank > 2)
		+	return; // skip
		+
		+	if (funcWriteTable[bank] != NULL) // Check for bank write callback
		+	{
		+	funcWriteTable[bank](address, value);
		+	}
		+	else if ((address & 0x0001) && (value & 0x80)) // Handle extended function
		+	{
		+	uint8 funcId = value & 0x3F; // Get function ID
		+	if (funcEnableTable[funcId] != NULL)
		+	funcEnableTable[funcId](value & 0x40, (address >> 1) & 0xFF); // Execute function specific code
		+	}
		+	else // Write to the given bank register
		+	{
		+	if (address & 1) // Set bank register MSB
		+	bankValue[bank] = ((value & 0x0F) << 8) \| (bankValue[bank] & 0x00FF);
		+	else // Set bank register LSB
		+	bankValue[bank] = (bankValue[bank] & 0xFF00) \| (value);
		+	}
		+	}
		+
		+	// Handle read access
		+	uint8 NEO16_Read(uint16 address)
		+	{
		+	uint8 bank = address >> 14; // Get the corresponding bank number
		+	if (bank > 2)
		+	return 0xFF; // skip
		+
		+	if (funcReadTable[bank] != NULL) // Check for bank read callback
		+	return funcReadTable[bank](address);
		+	else
		+	return romData[(bankValue[bank]) << 14 + (address & 0x3FFF)];
		+	}
		+	</syntaxhighlight>
		+
		+	=== Extension example ===
		+	Here is a pseudo code in C to handle a SRAM extension for NEO mapper:
		+
		+	<syntaxhighlight lang="c">
		+	uint8 sramSeg; // Current SRAM segment [0:15]
		+	uint8 sramBank; // Current bank where SRAM is selected (0xFF if not selected)
		+	uint8* sramData; // SRAM data (hardware specific)
		+
		+	// Write to SRAM
		+	void SRAM_Write(uint16 address, uint8 value)
		+	{
		+	sramData[(sramSeg * 0x2000) + (address & 0x1FFF)] = value; //
		+	}
		+
		+	// Read from SRAM
		+	uint8 SRAM_read(uint16 address)
		+	{
		+	return sramData[(sramSeg * 0x2000) + (address & 0x1FFF)];
		+	}
		+
		+	// Enable/disable SRAM feature
		+	void SRAM_Enable(bool enable, uint8 param)
		+	{
		+	if (sramBank != 0xFF) // Disable previous SRAM registration
		+	{
		+	if (funcWriteTable[sramBank] == SRAM_Write)
		+	funcWriteTable[sramBank] = NULL;
		+	if (funcReadTable[sramBank] == SRAM_Read)
		+	funcReadTable[sramBank] = NULL;
		+	sramBank = 0xFF;
		+	}
		+
		+	if (enable) // Enable a SRAM segment in the given bank
		+	{
		+	uint8 bank = param & 0x07; // Get bank number
		+	if (bank > 2)
		+	return; // skip (for NEO-16)
		+
		+	sramSeg = (param >> 4) & 0x0F; // SRAM segment number
		+	sramBank = bank;
		+	funcWriteTable[sramBank] = SRAM_Write; // Register SRAM callbacks
		+	funcReadTable[sramBank] = SRAM_Read;
		+	}
		+	}
		+
		+	// Initialize SRAM feature
		+	void SRAM_Init()
		+	{
		+	sramBank = 0xFF;
		+	funcTab[0x04] = SRAM_Init; // Register to function 0x04 (SRAM/FRAM feature)
		+	}
		+	</syntaxhighlight>
		+
		+	Then, you just need to call <tt>SRAM_Init()</tt> from <tt>NEO16_Init()</tt> to register the feature.

−	NEO ~~Mapper Extension~~ {{~~WIP~~}}	+	{{WARNING\|This page is still in the proposal stage and should not yet be considered an official specification.}}
		+
		+	Proposal for an extension to the [[NEO mapper]] format.
		+
		+	== Specifications ==
		+
		+	=== Principles ===
		+
		+	Any write operation to the NEO mapper with data bit 7 set to 1 and address bit 0 set to 1 is considered an access to extended features. In that case, the mapper bank register is not modified.
		+
		+	All other write operations should be considered normal access to the mapper's bank register.
		+
		+	The data contains:
		+	* The number of an extended function in the mapper
		+	* A bit indicating whether the function should be enabled or disabled
		+
		+	The address contains an 8-bit parameter to be passed to the function.
