Jens Arnold	bf6e0cd9d1	ZXBox: Clean up display init. Saves ~1KB on colour targets, and 4KB (coldfire)... >6KB (SH1) for greyscale targets, due to no longer using floating point math. * Name the 2bpp display routines correctly. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20621 a1c6a512-1295-4272-9138-f99709370657	2009-04-05 12:13:58 +00:00
Jens Arnold	feb5b15e9b	All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15998 a1c6a512-1295-4272-9138-f99709370657	2008-01-04 23:42:38 +00:00
Dave Chapman	05a7f14f8d	Initial commit of zxbox - a ZX Spectrum emulator ported by Anton Romanov. It theoretically runs on all targets, but I have not included it in the Archos builds because it is just too slow to be usable. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10950 a1c6a512-1295-4272-9138-f99709370657	2006-09-15 11:11:16 +00:00
