sl0pboy - a Game Boy Color emulator (companion to the gbos OS) https://git.sl0p.foo/sl0pboy.git/atom/src/render.c?h=master 2026-07-18T18:41:19Z 2026-07-18T18:41:19Z gbc dev gbc@localhost 2026-07-18T18:41:19Z urn:sha1:fa1579cc9f209dbeb14ab277dc9c4ac741ace57c Decimates the LCD N x N before the half-block encode so the monitor pane takes 160/N cols x 72/N rows. Display-only: capture, recording and sixel still read the full-res framebuffer. Decimation is max-luma pick, not box-average: terminal fonts are 1px bright strokes on dark background, and averaging dims them into grey mush (the 'blurry font' regression). Keeping the brightest source pixel of each block preserves stroke brightness and hue. 2026-07-16T22:27:18Z gbc dev gbc@localhost 2026-07-16T22:27:18Z urn:sha1:6c0eaf8469a3f4876cb067e11824a030bf37bcac - --chrome: draw a DMG-style 'sl0pboy' shell around the LCD in sixel mode, with a bitmap-font silk-screen (logo, labels), speaker grille, power LED, and buttons that light up while held. - LCD palette recolor (render_set_palette): remap the LCD to a 4-shade palette by luminance for the classic monochrome look ('dmg'/'green' pea green, 'pocket'/'gray'); applies to every render path. - Refactor the sixel encoder into generic build_palette_buf/encode_sixel_buf operating on any RGB888 buffer, shared by the bare LCD and the chrome canvas. - render_capture_size/frame: produce the exact displayed frame (recolor + chrome) as an RGB buffer, for screenshots and video recording. 2026-07-15T08:33:48Z gbc dev gbc@localhost 2026-07-15T08:33:48Z urn:sha1:63597fab346410974053294ec8f7103490b79ff5 In --sixel mode the emulator drew a status line (title/skip/[f]ast/q:quit) under the image; drop it so sixel output is nothing but the game graphics. 2026-07-14T21:26:49Z gbc dev gbc@localhost 2026-07-14T21:26:49Z urn:sha1:c879adc43b91a53eb7e76f232a39abb56d8144c1 Replace the input-only FIFO's limitations with a Unix-domain socket control channel (--sock) that is a superset of the button vocabulary plus emulator introspection: read/write bus memory, get/set CPU context, single-step, PC breakpoints, value-change watchpoints, run/pause. Being a socket it replies to each command and broadcasts async 'event stop ...' lines; a stored last-stop record (stopinfo) lets per-request clients recover a missed event. Add gbctl: a stdlib-python CLI that spawns a tmux pane running the emulator on a ROM, auto-resolves the socket, and drives it with terse verbs (cpu/read/write/ reg/step/break/watch/continue/pause/press/hold/screen/stop). The FIFO stays as legacy input-only. 2026-07-04T21:07:50Z gbc dev gbc@localhost 2026-07-04T21:07:50Z urn:sha1:f4ba890eb4b98e1a65a3d9fc8ba8f62dda66895b Emulation always runs at native rate (correct game speed); --frameskip N draws only 1 of every N+1 frames so a slow terminal no longer bottlenecks the loop. Adds --fps cap, --uncapped/--turbo, live [ ] and f keys, HUD readout, and an exit summary of emulated-vs-drawn fps. Replaces the confusing --render-fps. 2026-07-04T20:46:11Z gbc dev gbc@localhost 2026-07-04T20:46:11Z urn:sha1:54081ce90bf2b4cad803ab78db65b91c1217cc83 Adds --fifo [path] opening a named pipe that accepts button commands from any process. Supports momentary taps (a, start, name:N), deterministic hold/release (+name / -name), and 'release'. Merges with keyboard input; held state carries true key-up semantics the terminal can't provide. GBC_INPUT_DEBUG traces state. 2026-07-04T20:39:34Z gbc dev gbc@localhost 2026-07-04T20:39:34Z urn:sha1:894ddbe9bcf2bbd1da3af0429b6ed9550c0d4ce3 Only cells that changed since the previous frame are redrawn, using cursor positioning to skip unchanged runs. Static screens write nothing after the first frame (~108x reduction on acid2). SIGWINCH forces a full repaint. Verified pixel-exact against the framebuffer (11520/11520 cells, 0 mismatch). 2026-07-04T20:14:10Z gbc dev gbc@localhost 2026-07-04T20:14:10Z urn:sha1:ab07098f5b948a7aa2c46d2f82db299b84ea2d9b 2026-07-04T20:12:57Z gbc dev gbc@localhost 2026-07-04T20:12:57Z urn:sha1:5800f04eb0417c980fef2eddd78d8b60d19d0db5
