No$gba 2.5 - 模擬器

2007.10.03

help: updated gbatek standalone version 2.5 (about one hundred
news since 2.3)
vram viewer: supports extended palettes in bg map windows (eg.
magnetica demo)
nds/help: added ds 3d overview chapter (basics on geometry/rendering
engines)
nds/help: added ds technical data chapter (containing some basic
overview)
nds/help: replaced ds various chapter by new ds memory control/
timing chapter
nds/sound: fixed major unreported bug in 80x86 code sound_bias SWI
function
nds/3d/help: corrected shininess formula (ie. fixed that max cos 2
angle mess)
nds/3d/help: added caution: specular reflection WON'T WORK on camera
rotation
nds/3d/help: maths basics of vector-by-vector multiply (and purposes
thereof)
nds/3d/softlight: allows light+color nonsense double def (eg castlevania
clip)
nds/3d/softlight: much better light-accuracy, and now supports
shininess_table
nds/3d/softlight: lighting fully calculated by software (without opengl
light)
nds/timing: split timings for nds7 (fast access) and trashy nds9
(slow access)
nds/timing: split addr_clks_table to CODE/DATA
addr_clkc_table/addr_clkd_table
nds/timing: emulates "half" cycles on 66MHz/nds9 (tcm/cache and
n32/2 thumb)
nds/timing: emulates nds7 exmemstat gba-slot timing bits (like nds9
exmemcnt)
nds/timing/help: added detailed/tested nds7/nds9 code/data memory-timing
chart
nds/timing/cache: allows more CPU load on bios/mainram when cache is enabled
nds/timing: emulates shared N32 access time for two NDS9 thumb 16bit
opcodes
cpu/speedup: precalculates opcode-timings on interseg-jumps (usually
faster)
cpu/speedup: faster conditional opcode handling (maybe yet another 3%
faster)
cpu/speedup: thumb: uses 16bit reads (3% faster on non-32bit-aligned
addr's)
cpu/speedup: replaced dumb jmp exec_opcode by exec_opcode_mac
(ca. 10% faster)
cpu/speedup: added more code alignments in cpu-core (not significantly
faster)
nds/help: added note that 66MHz-nds9 actually runs MUCH SLOWER
than 33MHz-nds7
nds/cpu: emulates superslow nds9 memory access time (bios,wram,
vram,oam,etc)
nds/cpu: emulates operand-independend ARM9 multiply time
(eg. slow thumb time)
nds/wram: emulates wramcnt mapping (no idea if it's used by any
games though)
nds/3d: adjusted z-rounding (avoid opengl-clip-plane in club
house games demo)
cpu: emulates cp15-trace-id, debug: disass auto-comments on
trace-id and bist
nds/help: fixed key1 [scratch] writeback lsw/msw are exchanged
(thanks simon)
nds/help: cp15 info on trace-id, bist, cache debug/test, supported
cache cmds
cheat: fixed occassional crash on delete cheat (push/pop)
(thanks Hiei Youkai)
thanks: rockmanrotties for submarine (timing) and clubhouse
(clip) bugreports
