Il s’agit d’un \u00e9mulateur et d\u00e9bogueur de Sony Playstation cr\u00e9\u00e9 par le c\u00e9l\u00e8bre Martin Corth.
\nL’\u00e9mulation devrait \u00eatre compl\u00e8te avec la prise en charge de toutes les fonctions du mat\u00e9riel. Normalement tout fonctionne pleinement. N\u00e9anmoins Martin Korth n’a test\u00e9 son programme que sur une douzaine de titres, donc il peut y avoir des probl\u00e8mes sur d’autres jeux.<\/p>\n
<\/p>\n
Le BIOS est \u00e9mul\u00e9 \u00e9galement via un clone qui est gratuit (th\u00e9oriquement libre de droit) et plus rapide que le BIOS d’origine. Normalement no$PSX ne requiert donc pas de BIOS pour lancer les jeux de la console. Cependant il peut y avoir des probl\u00e8mes de compatibilit\u00e9 avec certains jeux. Dans ce cas, il faut employer une copie du BIOS officiel.<\/p>\n
<\/p>\n
Les CD-ROM sont support\u00e9s via un lecteur CD r\u00e9el. Il est \u00e9galement possible d’utiliser des images de disque aux formats .NRG, .CUE+.BIN et .ISO ou alors des ex\u00e9cutables .EXE.<\/p>\n
<\/p>\n
Les nouveaut\u00e9s sont les suivantes:<\/p>\n
<\/p>\n
– new: plain gaming-version (miniaturized nonsense emulator without debugger)<\/span><\/em> <\/p>\n T\u00e9l\u00e9charger No$PSX v1.8 (546,8 Ko)<\/a><\/p>\n T\u00e9l\u00e9charger No$PSX (Gaming version) v2.3 (204 Ko)<\/a><\/p><\/p>\n

\n-snapshots: survives snap loading even if old cdrom-image folder doesn’t exist<\/em>
\n– snapshots: added better (but slower) LZ-based .SNA file compression (optional)<\/em>
\n– snapshots: includes BIOS ROM (for loading regardless of bios versions\/clones)<\/em>
\n– expansion rom: prevents skip_intro patch on expansions (which may hook intro)<\/em>
\n– expansion rom: prevents tty_enable patch for caetla (which needs bios chksum)<\/em>
\n– expansion rom: supports actionreplay and xplorer io ports (namely switch=on)<\/em>
\n– expansion rom: supports actionreplay 2x128K mapping and normal xplorer mapping<\/em>
\n– bios-clone: fixed rename-function (added mov r4,r16)(ridgeracer sav overwrite)<\/em>
\n– gpu: prevents better-than-real-quads on concave\/twisted quads (crashbandicoot)<\/em>
\n– timers: supports separate dest\/overflow events, completion flags, dest changes<\/em>
\n– help: added specs and cautions on cdrom autopause (or autostop) feature<\/em>
\n– cdrom: implemented autopause feature with INT4(stat) on end of track (Rayman)<\/em>
\n– gpu: CpuToVram wraps from x=3FFh to X=000h with Y=SAME (Alundra memcard save)<\/em>
\n– gpu: fixed polygon height limit (don’t draw if height>=512) (for Spiderman)<\/em>
\n– cdrom: implemented authentic 2nd_response timings (Gundam Battle Assault 2)<\/em>
\n– help: added ‘CDROM – Response Timings’ chapters (some min\/max\/average timings)<\/em>
\n– help: corrected cdrom GetID description (only one response on DoorOpen\/SpinUp)<\/em>
\n– vram viewer: forces \u00ab\u00a0swap_buffers\u00a0\u00bb after timeout (avoids dracula mem overflow)<\/em>
\n– cpu: emulates cop0 bpc\/bpcm opcode fetch breaks (for cheat device booting)<\/em>
\n– help: fixed cop0 debug break description (bpc-then-bpcm, not vice-versa)<\/em>
\n– bios-clone: added dummy \u00ab\u00a0add r4,0,385h\u00a0\u00bb opcode at (for Xplorer bios hook)<\/em>
\n– bios-clone: moved gui-entrypoint to 80030000h (for Action Replay bios hook)<\/em>
\n– cdrom\/bugfix: bugfixed new cdrom-dma timing; minus intcount (dino crisis 1-2)<\/em>
\n– fileloader: allows to load\/debug\/emulate expansion roms (.rom and .fcd files)<\/em>
\n– help: new Cheat Devices chapter (code formats, i\/o ports, decryption, etc)<\/em>
\n– web: new no$psx forum: http:\/\/ngemu.com\/forums\/no-psx-discussion.147\/<\/a><\/em><\/p>\n
