Runner ported to Android arm64 as libmain.so (SDL). Working on the Thor: - FreeBIOS/no-dump boot, MPH AMHE0 title banks - Dual physical screens: top fills main display, bottom on Screen-2 - Bottom-screen touch -> DS stylus; right-stick direct aim - Fixes: dispatch-cache stack overflow (-O0 bionic), SDL_main linkage, stdio->logcat, ARGB->RGBA second-screen blit, single-window layout Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- android_gl_compat.h: GLES 3.2 header + shims for glMapBuffer, glGetTexImage (FBO+glReadPixels), glBindFragDataLocation (no-op), GL_BGRA_INTEGER - CMake: Android compute build uses GLES headers + libGLESv3/EGL, drops glad - ComputeHost: request GLES 3.2 ES context; skip glad loader on Android - Runtime: compute renderer is now selected (preferred) on the Thor Remaining: single-window GL surface for the compute context (Android blocks a second window), and GLSL translation (430 core -> 320 es + subgroup rewrite). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- frontend: enable gl_top (direct-GL compute) on Android single window; bottom screen routed to second display in the compute present path - GLES 3.2 context now initializes on the Thor's Adreno 740 (single-window blocker resolved) - shaders: #version 320 es + precision qualifiers; startTable uint literals - remaining: pervasive int/uint strictness in the shared Common shader math Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
int/uint strictness fixes in Common math (Div/Div64/umulExtended), span setup, BinCombined, and const buffer-offset initializers. Shaders 1-3 (InterpSpans, *, BinCombined) now compile; numbered on-device shader dump added to OpenGLSupport for fast line mapping. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
findLSB/findMSB->uint sweep; blend/bin int-macro casts. App still runs via software fallback throughout (compute init cleanly falls back).
All 33 compute shaders + present shaders ported to GLES 3.2 (int/uint strictness throughout: Div/blend/rasterise/binning/finalpass/AA + present shader version swap). Renderer now initializes as compute (no software fallback) and renders on-device. HUGE: the HD renderer path is live.
3x internal resolution (1344x576 3D) + 2x xBR texture upscaling both run on the Adreno 740 via GLES compute. TextureUpscale present shader version swap.
The 2D framebuffer is ARGB8888 (BGRA byte order), uploaded as GL_RGBA_INTEGER on GLES (no BGRA_INTEGER), which transposed red/blue. Swizzle the fallback texture (SWIZZLE_R=BLUE, SWIZZLE_B=RED) so 2D colors read correctly.
373 upstream commits: tier-2 live overlays, SDL3 default frontend (SDL2 kept as our Android backend), expanded native banks, upstream's own element-wise dispatch-cache clear (supersedes our Android stack fix). Android/GLES/ dual-screen patches re-folded into the new NDS_SDL_BACKEND structure.

Android / AYN Thor port of the runner
This is the working Android arm64 port behind Hunters Recomp, the MPH build for the AYN Thor (dual-screen Android handheld). Everything is gated so desktop builds are unaffected.
What's in it
GLES 3.2 backend for the compute renderer (
NDS_GLES, Android-only in CMake)android_gl_compat.h: platform GLES headers plus shims for the desktop-only calls:glMapBufferviaglMapBufferRange,glGetTexImagevia a read FBO +glReadPixels,glBindFragDataLocationno-op,GL_BGRA_INTEGERmapping with a texture swizzle on the 2D fallback texture to keep channel order correct,APIENTRYPspelling#version 320 eswith explicit precision qualifiers underNDS_GLES(compute, present, and texture-upscale shaders)GLSL int/uint strictness fixes in the compute shaders (not gated; pure correctness)
uint()/int()casts, matching return types. Verified on Adreno 740; desktop GL accepts all of it unchanged.Android platform wiring (all
__ANDROID__/ANDROID-gated)libmain.somodel),SDL_mainentry, stdio mirrored to logcatPresentationsurface with touch mapped to the stylus (android_second_screen.*); top screen fills the main display in both the SDL and direct-GL presentersTested
AYN Thor (Snapdragon QCS8550 / Adreno 740, Android 13), MPH AMHE-0 banks: boots, plays, saves; compute renderer active with internal resolution up to 4x and xBR texture upscaling.
Known issue I'm still chasing
After merging current main, on-device I see black frames during the opening FMV and a slightly softer final image than my pre-merge build on the direct-GL presenter path. May be related to the presenter refactor noted in the v0.6.0 notes; I can file a separate issue with logs.
Happy to split, squash, or rework any of this however you prefer.
