		nice menu, but why did you replaced the previous one in 05-15-2014 post ?

just because people didn't like it, so i reused a background from ps3's fba. but basically it's the same : new background with new font colors

Ah, OK.
The original menu looked nice to me, but you shouldn't trust my personal tastes ^^;

sure ! you'll win

also some speed improvements on zaxxon
v1 with bg : 16 fps
v2 : 23 fps (current picture)
vXXX : 55 fps (pal setting)

without using asm

it's really not easy to render bitmap with a decent speed !

			Great ! Which kind of trick did you used to improve performances ?

lookup tables with type integer instead of char
unrolled loop
pre-increment !!!

	
	
		
		
			for (unsigned int y = 16; y < 240; ++y) // x

		{

			UINT8 *dst = ((UINT8 *)ss_map264) - y; // * 0x100;

			UINT8 *src = zaxxon_bg_pixmap + ((y + yoffset) & 4095) * 0x100;

			UINT32 *srcptr = (UINT32 *)srcxmask[y];



			for (unsigned int x = 0; x < 0x20000	  // y

			{

				dst[x]             = src[*srcptr];

				++srcptr;

				x+=512;

				dst[x]             = src[*srcptr];

				++srcptr;

				x+=512;

				dst[x]             = src[*srcptr];

				++srcptr;

				x+=512;

OK, Thank you for the tricks
