seedds c392d56af0 Balatro (0100CD801CE5E000, update 1.1.3, LÖVE 11.4 "love-nx" with LuaJIT and SDL on SDK 18.3.2): game profile and the GL layer LÖVE needs, plus four general changes. Plays on the iPhone by touch; on the Mac from the intro and the title into a run and its tutorial, at 60 fps with sound, about 0.65 GB resident and flat over three minutes. The game is Lua source in the RomFS and renders with NVIDIA's desktop OpenGL through EGL, as Digimon does. GL layer (dm/gfx/gl/hle_gl.m): LÖVE reads GL_CONTEXT_PROFILE_MASK and takes its core-profile paths only when it says core (with a compatibility profile it streams vertices from client memory, which Metal cannot draw from), so the layer answers core and implements what those paths use, about 150 functions in all against Digimon's 79: persistently mapped buffers (glBufferStorage, glMapBufferRange: the shared MTLBuffer's own memory), glBufferSubData in command order, fences (a fence is the serial of the command buffer being recorded; a wait on one still recording commits it), glBindAttribLocation (the game's attribute index of each Metal input, set at the link) and current attribute values (glVertexAttrib4f: LÖVE's VertexColor and ConstantColor are disabled arrays), glGetActiveUniform and the uniform read-backs, every glUniform* form, glTexStorage2D / 3D with their level counts, 3D and 2D array textures (LÖVE makes a default of each type on 96 units), GL_TEXTURE_SWIZZLE_* (its font glyphs are RG8 read as R, R, R, G), glGenerateMipmap as a blit (the game's images are mipmapped), instanced and base-vertex draws, separate read and draw framebuffers, glBlitFramebuffer (colour, same size), glReadPixels, glClearBufferfv, glFrontFace and the EGL calls SDL makes; stack arguments of the functions with more than eight are 64-bit, as AAPCS64 lays them out. DM_GL_STUBS=1 gives every GL name the layer lacks a stub of its own that reports its first call, instead of a null pointer. Shaders: LÖVE puts its 35 GLSL sources together at run time in Lua, so the NSP script captures them on the Mac as it does Super Mario Galaxy's SPIR-V (capture_shaders now serves both, profile gl_capture.tsv; profile_guess.py's gl_capture rule: an OpenGL game with no GLSL source in its RomFS or main), and gl_shaders.py keeps a bool uniform's declared type (a uint in SPIR-V; LÖVE's Shader:send takes only a boolean for a bool) and takes from main only strings that start with '#version <number>' (Balatro's main has glslang's messages). General: profile_guess.py leaves vkGetInstanceProcAddr, SDL's Vulkan loader, out of its Vulkan count (Balatro's provisional profile said Vulkan; Hades and both Galaxies import 99 or 100 Vulkan functions); OpenAudioRenderer without an event now starts the host's render thread too (hle_audren.c ar_open: only the form with an event did, and such a game was silent); loader_census.py follows registers in a straight line (adrp, add, loads through relocated GOT entries, mov, csel), for LÖVE's glad, whose pointers are globals its code keeps the addresses of in registers; and the iPhone gamepad has a third layout, Tap (profile pad_layout touch, which needs op_mode handheld; DM_GAME_PAD_LAYOUT replaces DM_GAME_PAD_FULL): no control but the layout button, every touch to the game, offered in the layout cycle only in handheld mode. Profile: op_mode handheld (the Switch build plays by touch there), pad_layout touch, gl_capture.tsv. A Lua error makes Balatro quit (its Switch error handler), and love-nx's video worker is then deleted twice (main+0x339c00): the bring-up notes say how the errors were found. Checked: the NSP script packs it from the NSPs alone (the capture in under a second, 35 shaders for the Mac and iOS, an 82 MB IPA), tool tests pass, profile_guess.py --check changes no other profile; Digimon was not rerun (its files are not on hand). README (games table, a Mac picture of the title), AGENTS.md (47 → 48), docs/development.md, docs/agents and the READMEs of dm/games and dm/gfx say so
