Une nouvelle version de cet \u00e9mulateur NeoGeo Pocket vient de sortir dont voici les nombreuses am\u00e9lioarations:
\n
\n– Trimmed out the old history from this file. I want to start with a clean
\nsheet as this version is greatly improved over the last versions.
\n– Removed the 32bit parity function and calls to it, as no instructions are
\nsupposed to use it. This should reclaim a few extra clock cycles and improve
\naccuracy. Also, optimised the 8 and 16 bit parity functions, thanks Judge_
\n(Haven’t fixed DAA yet though! \ud83d\ude42
\n– Improved faking of EEPROM bios calls by returning a success status
\nmessage. This improves \u00ab\u00a0Fatal Fury\u00a0\u00bb so you can now use the ‘reset memory’
\noption from the config menu.
\n– Added instructions BS1F,BS1B. This improves the SNK logo in \u00ab\u00a0KOF – Battle
\nDe Paradise\u00a0\u00bb. It also improves \u00ab\u00a0Koi Koi Mahjong\u00a0\u00bb internally, but I don’t
\nknow in what way as it’s in Japanese.
\n– Lowered the battery power status to within actual hardware limits.
\n– Memory accesses ignore the top 8 address bits when reading and writing.
\nThis has fixed a large number of games that previously had graphical
\ncorruption.
\n– Added a special HACK for \u00ab\u00a0Puyo Puyo 2\u00a0\u00bb because it does work very well,
\nexcept for a crazy routine at the beginning that overwrites critical system
\ndata!
\n– Fixed a small bug in the V flag emulation of \u00ab\u00a0DEC #3,(mem)\u00a0\u00bb
\n– Fixed a small bug in \u00ab\u00a0DEC #3,r\u00a0\u00bb, it wasn’t setting the N flag correctly.
\n– Fixed a set of stupid bugs in \u00ab\u00a0ADD (mem),R\u00a0\u00bb, \u00ab\u00a0ADC (mem),R\u00a0\u00bb, \u00ab\u00a0SUB (mem),R\u00a0\u00bb,
\n\u00ab\u00a0SBC (mem),R\u00a0\u00bb, \u00ab\u00a0ADD (mem),#\u00a0\u00bb, \u00ab\u00a0ADC (mem),#\u00a0\u00bb and \u00ab\u00a0SBC (mem),#\u00a0\u00bb as they were adding the wrong sized values together (stupid cut and paste error!).
\n-Fixed just about every game that wasn’t working. The short list includes:
\n\u00ab\u00a0Bikkuriman 2000\u00a0\u00bb, \u00ab\u00a0Bust-a-Move\u00a0\u00bb, \u00ab\u00a0Big Bang Pro Wrestling\u00a0\u00bb, \u00ab\u00a0Delta Warp\u00a0\u00bb,
\n\u00ab\u00a0Dynamite Slugger\u00a0\u00bb, \u00ab\u00a0Dive Alert\u00a0\u00bb, \u00ab\u00a0Gals Fighters\u00a0\u00bb, \u00ab\u00a0Crush Roller\u00a0\u00bb, \u00ab\u00a0Metal
\nSlug\u00a0\u00bb, \u00ab\u00a0Pocket Reversi\u00a0\u00bb, \u00ab\u00a0SNK vs CAPCOM\u00a0\u00bb, \u00ab\u00a0Neo Turf Masters\u00a0\u00bb … – Well, you
\nget the picture!
\n– Made a huge number of optimisations: Improved speed drastically by
\nchecking timers and interrupts less often. Optimised register access a bit,
\nremoving a layer of indirection. Optimised status flag get and set methods
\ninto macros.
\n– Fixed STCF instruction (all modes) – it was very badly written the first
\ncouple of times \ud83d\ude42 Also removed Word mode from \u00ab\u00a0STCF #3,(mem)\u00a0\u00bb and \u00ab\u00a0STCF
\nA,(mem)\u00a0\u00bb as this isn’t actually allowed. Also removed Word mode from \u00ab\u00a0LDCF
\nA,(mem)\u00a0\u00bb for the same reason.
\n– Changed the emulation loop to currectly emulate twice as many TLCS-900h
\ninstructions as Z80 ones. This only applies to the release version, the
\ndebug build has a 1:1 ratio of instructions for simplicity. This has no
\nnoticable effect on accuracy, just performance. The debugger runs at about
\n1\/3 of the speed of the release version unfortunately.
\n– Added a speed display to the window title. Inspired by VisualBoyAdvance,
\nit shows as a percentage of the correct refresh rate of 59.95 fps. Note that
\ncycle counting for instructions hasn’t been completely implemented, so the
\nvalue will not be entirely accurate, but it does give a rough estimate of
\nperformance. In case you are wondering, my 600Mhz PIII is capable of about
\n80-90% for most commercial games. I think this value will increase when
\ntiming becomes more accurate. Certainly – no games feel slow any more!
\n– Input is now polled every frame. It’s possible to perform special moves in
\nfighting games, so I think this frequency is adequte.
\n– The Real Time Clock data is updated every frame as well. This is more
\noptimal than older versions where it was updated before every instruction.
\n– Optimised the graphics Z-Buffer (used for correct sprite priorities) as it
\nonly needs to know about the current scanline.
\n– Optimised the graphics update by having two code paths, one for each
\ncolour depth. This has raised overall performance a few percent.
\n– Both executables are now packed using UPX for a smaller download.
