Library configuration (msxgl_config.h):

// VRAM addressing unit
// - VDP_VRAM_ADDR_14 ............. Use 14-bits 16K VRAM addressing for MSX1 (u16)
// - VDP_VRAM_ADDR_17 ............. Use 17-bits 128K VRAM addressing for MSX2/2+/turbo R (u32)
#define VDP_VRAM_ADDR				VDP_VRAM_ADDR_17

// VDP X/Y units
// - VDP_UNIT_U8 .................. X and Y use 8-bits values
// - VDP_UNIT_X16 ................. X use 16-bits and Y use 8-bits values
// - VDP_UNIT_Y16 ................. X use 8-bits and Y use 16-bits values
// - VDP_UNIT_U16 ................. X and Y use 16-bits values
#define VDP_UNIT					VDP_UNIT_X16

// VDP screen modes (additionnal limitations come from the selected MSX_VERSION)
#define VDP_USE_MODE_T1				TRUE	// MSX1		Screen 0 Width 40
#define VDP_USE_MODE_MC				TRUE	// MSX1		Screen 3
#define VDP_USE_MODE_G1				TRUE	// MSX1		Screen 1
#define VDP_USE_MODE_G2				TRUE	// MSX1		Screen 2
#define VDP_USE_MODE_T2				TRUE	// MSX2		Screen 0 Width 80
#define VDP_USE_MODE_G3				TRUE	// MSX2		Screen 4
#define VDP_USE_MODE_G4				TRUE	// MSX2		Screen 5
#define VDP_USE_MODE_G5				TRUE	// MSX2		Screen 6
#define VDP_USE_MODE_G6				TRUE	// MSX2		Screen 7
#define VDP_USE_MODE_G7				TRUE	// MSX2/2+	Screen 8, 10, 11 & 12

#define VDP_USE_VRAM16K				TRUE	// Use 16K VRAM access functions on MSX2
#define VDP_USE_SPRITE				TRUE	// Use sprite handling functions
#define VDP_USE_COMMAND				TRUE	// Use VDP commands wrapper functions
#define VDP_USE_CUSTOM_CMD			FALSE	// Use custom VDP commands through data buffer
#define VDP_AUTO_INIT				TRUE	// Call VDP_Initialize() at the first call to VDP_SetMode()
#define VDP_USE_UNDOCUMENTED		TRUE	// Allow the use of undocumented screen mode (WIP)
#define VDP_USE_VALIDATOR			TRUE	// Handle some option specific for each VDP mode (highly recommended)
#define VDP_USE_DEFAULT_PALETTE		FALSE	// Add data for default MSX2 palette
#define VDP_USE_MSX1_PALETTE		FALSE	// Add data for default MSX1 palette
#define VDP_USE_DEFAULT_SETTINGS	TRUE	// Auto-initialization of common VDP feature
#define VDP_USE_16X16_SPRITE		TRUE	// Use 16x16 sprites mode
#define VDP_USE_RESTORE_S0			TRUE	// Do restore of status register pointer to S#0 (needed onlt for default BIOS ISR)
#define VDP_USE_PALETTE16			TRUE	// Use 16 entries palette (use only 15 entries otherwise)

// ISR protection while modifiying VDP registers
// - VDP_ISR_SAFE_NONE ............ No ISR protection (for program not using VDP interruption)
// - VDP_ISR_SAFE_DEFAULT ......... Protect only VDP register pair writing (default behavior; ISR can read/write registers but VRAM ones)
// - VDP_ISR_SAFE_ALL ............. Protect all VDP writing process
#define VDP_ISR_SAFE_MODE			VDP_ISR_SAFE_DEFAULT

// Initial screen mode setting
// - VDP_INIT_OFF ................. Force option to be disable
// - VDP_INIT_ON .................. Force option to be enable
// - VDP_INIT_AUTO ................ Determining the best value for the context
// - VDP_INIT_DEFAULT ............. Keep default value
