Pokemon Yellow disassembly with SL0P mods: fastboot, SECRET SL0P WARP MENU, custom intro splash https://git.sl0p.foo/pokeyellow.git/atom/home?h=master 2026-07-15T11:37:56Z 2026-07-15T11:37:56Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T11:37:56Z urn:sha1:27c01477dffa3f0aa66d531e5b5ed1bdc54609e3 Per feedback, EXPLORE should page whole screens on button presses (instant redraw), not move/walk the character. Ripped out the walk-engine approach entirely -- reverted the CollisionCheckOnLand noclip hook and the OverworldLoop simulated-joypad paging hook, and removed both helpers. EXPLORE is now a self-contained camera loop that renders straight from the map block buffer: - view pointer = wOverworldMap + (by+1)*stride + bx (LoadCurrentMapView) - a d-pad press shifts the camera coords by ~one screen and re-renders - at a map edge it crosses to the connected map using that connection's alignment offset (or clamps if none), LoadMapData + re-render - B restores the origin view + returns to the SL0P menu No character walking, sprites hidden for a clean camera. Verified: within-map paging steps a screen at a time, seams cross with correct offsets (Pallet -> Route1 -> Viridian), 25-page random stress with no corruption, and normal gameplay resumes after exit. 2026-07-15T10:15:50Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T10:15:50Z urn:sha1:259c6b8ec4524dcd4a75da065106107f2165b202 Ground-truth from render_overworld.py showed Kanto is ONE seamless world joined along shared edges with per-connection offsets -- so a map-by-map browser is the wrong model. Replaced it with noclip free-roam that leans on the engine's own player-walk + connection-crossing machinery (which already handles seams/offsets correctly): - wSlopNoclip flag (reused the dead wUnusedObtainedBadges byte at D356, 0 r/w, not unioned, in the saved region -> safe). - CollisionCheckOnLand: 5-byte hook at the top -> when noclip is set, return no-collision. Freed the room in ROM0 by deleting the unreferenced Func_0db5 (dead farcall LoadToggleableObjectData) in LoadMapHeader. - EXPLORE menu entry now just toggles wSlopNoclip and closes the menu, dropping you into the overworld to glide through walls/NPCs/ledges and walk across map connections exactly as the world data defines them. Verified: Pallet -> (walk north through the fences) -> seam-cross into Route 1 at y=35 -> continue north; toggle off restores collision (player blocked). 2026-07-15T00:01:51Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T00:01:51Z urn:sha1:849fc45bc57e9a1f85c4fa98103ec04991406627 Refactor the flat warp menu into a table-driven top-level SL0P MENU opened by SELECT. Each entry = a name in SlopMenuText + a routine in SlopMenuHandlers; handlers return carry set (a warp was started, exit) or clear (back to the menu). Ships two entries: WARP -> WarpSubmenu (the 13-destination town list) HEAL -> SlopHealParty (restore party HP + clear status), demoing an action Shared open/close display handling (hide sprites, single-space flags, wTileMap push, restore). Add an entry by appending a name+handler and bumping SLOP_MENU_COUNT. (renamed engine/warp_menu.asm -> engine/slop_menu.asm) 2026-07-14T22:37:04Z Ash Ketchum no-reply@sl0p.foo 2026-07-14T22:37:04Z urn:sha1:cbd75bcf8a14a647469e6e89c9c8a816fff9bc10 - home/overworld.asm: SELECT in the overworld farcalls WarpMenu, then restarts the overworld loop so the fly-warp flags get processed. - engine/warp_menu.asm (new): WarpMenu reuses the fly-warp machinery (wDestinationMap + BIT_FLY_WARP/BIT_USED_FLY). B1 warps to Pallet unconditionally to validate the hook; the real destination menu is next. - Moved the fastboot intro-skip out of home/init.asm into PlayIntro (bank 10) to reclaim ~10 bytes of home ROM0 for the overworld hook. Net boot behavior is unchanged; new-game path still shows the intro. 2026-07-14T22:28:26Z Ash Ketchum no-reply@sl0p.foo 2026-07-14T22:28:26Z urn:sha1:d52815caa2c0f385ae61e38ecc7b5bddd7ccf7b3 Three small hooks, all gated on CheckForPlayerNameInSRAM (carry = save present): - home/init.asm: skip 'predef PlayIntro' when a save exists - engine/movie/title.asm (PrepareTitleScreen): jp MainMenu, skipping the title screen (only the boot path hits PrepareTitleScreen; return-to-title paths jp DisplayTitleScreen directly, so they're unaffected) - engine/menus/main_menu.asm (MainMenu): after TryLoadSaveFile, if wSaveFileStatus==2 jp SpecialEnterMap, skipping the CONTINUE menu Exported CheckForPlayerNameInSRAM (:: ) so home/init.asm can farcall it. New game (no save) path is fully preserved. Ship pokeyellow.gbc only; the _DEBUG build overflows home ROM0 by 8 bytes with the init hook. 2026-06-24T18:43:48Z Yoann Fievez yoann.fievez@gmail.com 2026-06-24T18:43:48Z urn:sha1:d150f7f4f49e9dda08c52199159b30ae9b4f00e8 - Rename `wd471` to` wPikachuSpawnStateFlags`, with `BIT_PIKACHU_SPAWN_*` bits - Rename `wd492` to `wPikachuMapScriptFlags`, with `BIT_PIKACHU_MAP_*` bits - Introduce `PIKAMOVEMENT_*` constants for `ApplyPikachuMovementData` - Refactor `BillsHouse` scripts and Pikachu/Bill movement data 2026-01-18T04:38:33Z dannye 33dannye@gmail.com 2026-01-18T04:38:33Z urn:sha1:bc2354dd6626ce28bb9561547ed2107cfa56c18e 2026-01-08T03:05:37Z Rangi 35663410+Rangi42@users.noreply.github.com 2026-01-08T03:05:37Z urn:sha1:0e49aef88ef94b9d3e80d89e4eb718e9425045df 2026-01-08T03:05:20Z Rangi 35663410+Rangi42@users.noreply.github.com 2026-01-08T03:05:20Z urn:sha1:fe1e76466b293c83e6cd3a7d4639fb3c49da26ad 2025-12-15T20:14:17Z Narishma-gb 194818981+Narishma-gb@users.noreply.github.com 2025-12-15T20:14:17Z urn:sha1:e9d3324bc06faa7de3b7a35d1f9429e610e8a761
