【.pak Archive Info】
    the .pak is actual type of archive with directory.
    meta-data according to practical situation, can be bmp, ogg, bin(binary script) and so on.
    
    	header:
		s8 magic[4];		// "PACK"
		u32 index_entries;	// resource number(every item with variable length)
		u32 swap_flag;		// index segment byte data whether need swap high/low nibble
	index segment:
		s8 name[32];	// resource name(*new pak archive saving 32 wchar_t)
		u32 uncomprlen;	// resource data length	after decompressing
		u32 comprlen;	// resource data length(if in no compression, value of field is 0) 
		u32 offset;	// resource data offset(count from header)
	data: 	
		closely behind index segment. if comprlen isn't 0, data is lzss compressed; otherwise is uncompressed data.

【.opf Resource Info】
    the .opf is actual type of resource without directory.
    meta-data is bmp.
    
    	header: 
		s8 magic[4];		// "OPF "
		u32 width;		// image width
		u32 height;		// image height
		u32 color_depth;	// image color depth
		u32 line_length;	// image line length
		u32 dib_offset;		// RGB data offset(count from header)
		u32 dib_length;		// RGB data length
		u32 reserved;		// 0
	data: 	
		closely behind index segment. usually value of dib_offset is 32; if image is in 8-bit, next to header is 1024 bytes palette data, so value of dib_offset become 1024+32。

【.op2 Resource Info】
    the op2 is actual type of resource without directory.
    meta-data is bmp.
    
    	header:
		s8 magic[4];		// "OPF2"
		u32 width;		// image width
		u32 height;		// image height
		u32 color_depth;	// image color depth
		u32 line_length;	// image line length
		u32 dib_offset;		// RGB data offset(count from header)
		u32 dib_length;		// RGB data length
		u32 comprlen;		// compressed RGB data length(lzss)
