Orbit64 v1.0.98

Built from d568e7f on 2026-10-03.

Changes

• Compatibility page from the QA data; probe frame budget; README and QA.md up to date (d568e7f)
• tools: game QA - routes, replay, HLE-vs-LLE judging, OCR screen reader (517f850)
• RDP (HLE): a viewport with z translation 0 is not "no viewport" (Madden Football 64) (803959a)
• RDP (HLE): no depth buffer in RDRAM until a depth image is set; faster native pass (17ac9c9)
• Android: Build orbit64 as shared library for Android NDK (a11ed9a)
• CI: Add Linux PowerPC 64 LE and Android (ARM64 & x86_64) targets (cedc98c)
• CI: Fix QEMU dynamic linker paths for ARM/RISC-V and apply NetBSD paxctl W^X flag (2370973)
• CI: Add Haiku OS, fix NetBSD X11 sets, and optimize ARM/RISC-V cross-compilation (1a4b8b4)
• CPU: Add portable 64x64 to 128-bit multiplication helpers for 32-bit platforms and fix NetBSD build (43be93a)
• CI: Pass docker platform flag for emulated Linux armhf and riscv64 (6349ed0)
• CI: Fix 32-bit layout assertions and update CI targets for OpenBSD 7.9, NetBSD, Linux ARMv7 and RISC-V 64 (a645a9c)
• CI: Add OpenBSD, NetBSD, DragonFly BSD, Windows x86, Linux x86 and Musl targets (0e2a96c)
• Build on FreeBSD: its <sys/endian.h> already defines bswap16/32/64 (4dff741)
• CI: FreeBSD x64 and ARM64 builds in the release (2201c93)
• RDP (bit-exact): pixels on the GPU, internal resolution included (aae2617)
• RDP (HLE): 1-cycle level of detail from the next two pixels along the row (d5dc07b)
• RDP (fast low-level): keep polygon corners that are a hair apart (0d9d5b0)
• RDP (HLE): TMEM addresses wrap like the hardware's; no swapped rectangles (7a674c3)
• RDP (HLE): other modes start as the microcodes set them (dither off) (b020a7f)
• RSP: the SDK 2.0G Sprite2D microcode runs on the low-level RSP (bbd5484)
• RDP (HLE): 8-bit colour images; skip shading pixels the depth test rejects (9378a68)
• RDP (HLE): texels through the TLUT for every format, CI texels without one (1f60e1c)
• RDP (HLE): dithering, texture coordinates at the pixel corner; exact VI at 1x (1b702a0)
• RDP (HLE): texture rectangles from their edges in quarter pixels (b763158)
• RDP (HLE): depth buffer in RDRAM, 8-sample coverage, viewport depth range (3ab4e9a)
• RDP (HLE): the bit-exact RDP's pixel pipeline in the fast renderer (2ab7803)
• --dump-ram also prints the CPU's pc, CP0 exception registers and GPRs (7e49b5e)
• HLE: raise the DP interrupt only for tasks that ran a G_RDPFULLSYNC (78836a2)
• HLE: G_CULL_BOTH draws normally, as on the real microcode (Mortal Kombat 4 runs without LLE) (dea3903)
• RDP: in COPY mode the alpha test ignores the blend colour (texels with alpha 0 are dropped) (3f0d568)
• CIC 6106: leave the IPL3 words Cruis'n World checks in RDRAM (it no longer spins on purpose) (f3cae2b)
• RDP: with TLUT enabled every 4/8-bit texel goes through the palette, whatever the tile format says (Madden 2000 grass was grey noise) (319620f)
• Site: show all nav links on mobile (Compatibility, Download, FAQ) in a second row (0dfe799)
• Game status: a killed run no longer destroys the previous result (31052f6)
• Game status: fix list, --redo-list, CPU-drawn games, menu navigation (dec0d61)
• osTvType from the header's country code; PAL frames have 625 lines (93f90fa)
• Cartridge ROM write latch: A Bug's Life and Toy Story 2 boot (e0c264e)
• Debugger: Object Viewer captures geometry under LLE graphics (c950208)

• Site: x86-64 and ARM64 tags, ARM64 in search metadata and FAQ (77fd016)
• CPU: SQRT.S/SQRT.D use the host sqrt instruction like the JIT (5ffc852)
• CI: Linux and Windows ARM64 builds; run the JIT self-test on every platform (ec3c365)
• Game compatibility page (0969058)
• Game status tools: play every ROM and record how far it gets (d3f4e4d)
• Bit-exact RDP at internal resolution; LLE save state fixes (0858a35)
• Boot: copy each CIC's IPL3 tail to the start of RDRAM (8d8acc7)
• Low-level RSP/RDP: bit-exact RDP and VI (edf5d8b)
• Bus: cache recent TLB translations (c7b8e4c)
• Fast3D/F3DEX gSPForceMatrix (G_MV_MATRIX_1..4) (d9e3257)
• Wave Race 64's microcode (F3DWRUS) (74944bd)
• tools/test_set.py: a small test set picked from a full sweep (31b6614)
• Save type auto-detection; osRomBase is the KSEG1 address (fa303c4)
• Conker TRI4: the second six indices start at bit 0 of w0 (3ce6c75)
• Conker's Bad Fur Day microcode (F3DEXBG); F3DEX2 G_MV_MATRIX (0f17d25)

• ORBIT64_PICK_DUMP: save the picked draw's tiles, decoded (b2972f8)
• RDP: decal depth mode (ce8d401)
• Blender: coverage blending for anti-aliased edges (ea3bde1)
• Fog for the Diddy Kong Racing / Jet Force Gemini microcodes too (6062fdf)
• RDP: fog, both blender cycles, alpha from coverage (ecedb73)
• RDP: texture level of detail (mip-mapping, sharpen, detail textures) (3c788f5)
• Conker's Bad Fur Day: emulate its F3DEXBG microcode (4341786)
• Add a low-level RSP interpreter for the tasks the HLE doesn't know (6dad2a4)
• Yoshi's Story boots; S2DEX microcode switches, texture loads and palettes fixed (6e5233b)
• Boot: leave SP DMEM/IMEM as the 6101/6102/6103 IPL3 does (85d37a8)
• Diddy Kong Racing and Jet Force Gemini microcodes; VI shows 237 lines (c5dd438)
• x64 JIT: chain blocks into each other (fc7b2ea)
• Emulate controller accessories: Rumble Pak, Transfer Pak, Controller Paks on every port, Expansion Pak toggle (da3a11e)
• Thank Mupen64Plus on the project page and in the README (0a6c3c9)
• Say that Orbit64 is a work in progress on the project page and in the README (9d81c44)
