\nLes changements:<\/strong>
\n 
\nLe syst\u00e8me de mise \u00e0 jour passe de SVN \u00e0 GIT, du coup le nom des versions changent, par simplicit\u00e9 j’utiliserai un syst\u00e8me par date de release plus compr\u00e9hensible que le par d\u00e9faut de GIT.
\n 
\n– Quad triangle path fix\/improvement by @toxieainc in #348
\nPPC – port recent MAME changes and other spec compliant fixes (#347)
\n 
\nPPC Fixes from MAME (and some minor custom ones):
\n – mtfsf \/ mtfsfi: fixed the bit masks for the FPSCR fields they write
\n – fcmpo: now flags an invalid compare (VXVC), sets FX when that flag is new,
\n and respects the VE enable bit
\n – sraw: shifts a local copy of rS, so the result is right when rA and rS are
\n the same register
\n – subfme: computes the carry flag (CA) with SET_ADD_CA
\n – subfzeo: overflow is computed from the saved original rA
\n 
\n Undefined behaviour removed:
\n – rfi: clears the low 2 bits of the return address (& ~3)
\n – rlw* rotates: no more shift by 32 ((32-sh)&31)
\n – mulli \/ neg: calculated unsigned, so overflow is defined
\n – fctiw \/ fctiwz: clamp in double first and check for NaN, so x86 and ARM
\n give the same result
\n 
\n Left as-is, for now (no game triggers it?!): the rounding-mode handling (fesetround)
\n 
\n TODOs added for later:
\n – dcbz is still a no-op
\n – rfi should restore only some MSR bits (mask 0x87C0FFFF)
\n – SET_VXSNAN sets only FX
\n – fcmp shouldn’t touch the C bit
\n – frsp ignores the rounding mode (RN)
\n – mtfsf should recompute FEX and VX
\n 
\n – add clearer comments, make NaN checking more robust, and test all new changes against
\n– Misc fixes
\n 
\nA noter qu’un nouveau fork ajoutant le support du Sinden<\/a> est dispo ici<\/a>.<\/em>
\n <\/p>\n

\n

 
\nAjout:
\n– correction des musiques dans sega rally 2 (mix)
\n– correction musique 1er niveau 2joueurs (la cave rouge) dans vf3 (pas s\u00fbr de la modif, et donc cela peut \u00e9ventuellement entrainer d’autre probl\u00e8mes sonore sur d’autre jeux).<\/del>(inclut officiellement)<\/p>\n
