Pokemon Yellow disassembly with SL0P mods: fastboot, SECRET SL0P WARP MENU, custom intro splash https://git.sl0p.foo/pokeyellow.git/atom/engine/slop_menu.asm?h=master 2026-07-15T19:24:29Z 2026-07-15T19:24:29Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T19:24:29Z urn:sha1:397f583158195e85118c4027cf18e2536e8d1452 The screensaver used to return through .renderArrows (reloading the font, re-clearing/re-arming OAM+LCDC -- all pointless when arrows are hidden) plus an idle DelayFrame between every page, giving a ~1-frame hitch each screen. Add .afterMove: in saver mode it skips all that and dispatches the next direction immediately, so in-map pages chain back-to-back and the camera scrolls continuously. Manual EXPLORE still redraws its arrows as before. (Map-boundary crossings still briefly freeze while LoadMapData reloads the neighbour -- inherent to the full map load; a same-tileset fast path would be a larger, riskier change.) 2026-07-15T14:30:21Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T14:30:21Z urn:sha1:b6ed7736b92e9772626e6c457b2cb28c9d63411c The instant cheats (MONEY/HEAL/COINS/BADGES/DEX/MAXTEAM/TEACH/HMS/REPEL, NOWILD, and ITEMS-give) dropped you straight back to the menu with no sign anything happened. Add SlopConfirm: play the item jingle and flash a centred message box for ~0.8s before returning. NOWILD reports WILD MONS ON/OFF to match the new state. 2026-07-15T13:46:49Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T13:46:49Z urn:sha1:92856fd4b4908939ff4998a84369d4b9ac097b7a Crossing a map connection applies the connection's alignment offset blindly. At an edge position the connection doesn't span, the resulting coord lands outside the neighbour (e.g. Y = -8 = $f8), and since the bounds checks then operate on the wrapped value the camera roams far outside the map, rendering whatever WRAM lies past wOverworldMap as on-screen garbage. SlopClampCoords (run in .renderView, i.e. after every entry/cross LoadMapData) clamps wYCoord to [0,maxY] and wXCoord to [0,maxX] of the freshly-loaded map. Verified: 120-sample saver soak across 19 maps -> 0 out-of-bounds; manual EXPLORE crossing unaffected. 2026-07-15T13:35:32Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T13:35:32Z urn:sha1:038a9bdb6e3520912477d254177e91be179ce813 - Drop the occasional junction turn: keep the current heading until it is actually blocked, then turn onto a random non-U-turn direction. - Fix a freeze: a map's far edge (maxY/maxX = wCurrentMap*2 - 1) is always odd, but scroll moves round down to even coords, so the camera stops one coord short and 'coord != max' never flagged the edge as blocked -> the wander got stuck clamping forever. SlopValidDirMask now treats a direction as open only if there are >= 2 coords of room (one even step) or a connection to cross. 2026-07-15T13:23:39Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T13:23:39Z urn:sha1:eeb61bd9aa3ad514d685b82a635a8b7d4511339a New menu entry that auto-drives the EXPLORE camera across the overworld: - persistent-direction wander (DFS-ish): keep heading, turn only when blocked or occasionally at a junction, never an immediate U-turn. SlopSaverPickDir synthesises a d-pad direction into the normal EXPLORE dispatch, so it inherits smooth scrolling and smooth map-edge crossing. - arrows hidden; player/Pikachu never drawn (clear+freeze OAM right after every LoadMapData, before the first frame renders - also fixes a brief player flash at crossings in manual EXPLORE). - any button wakes it back to the menu. State byte wSlopSaverDir reuses wUnusedCreditsByte (0=off, else current dir). 2026-07-15T13:01:08Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T13:01:08Z urn:sha1:1a494d70ad252b08185342cbfaae018740fcde30 At a map boundary, smooth-scroll the remaining (even) distance up to the edge, then either cross into the connected map (one unavoidable instant load) or, with no connection, stop smoothly at the edge. Previously any edge move hard-jumped a whole screen; now only crossing from exactly on a boundary snaps. 2026-07-15T12:44:55Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T12:44:55Z urn:sha1:2749e462a29ec323fee27dfc674f99d044f04706 2026-07-15T12:09:43Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T12:09:43Z urn:sha1:01a1241e71e3aabfcaf36fee71916654dd95f407 In the paging camera, A now drops the player onto the map you're looking at. It scans outward from the screen centre (wTileMap col 8,row 9 = the view centre) for the nearest tile that IsTilePassable, adjusts wYCoord/wXCoord to it, sets wDestinationWarpID=$ff so LoadMapData enters at those coords, and returns carry set to close the menu and resume the overworld right there. Factored the view- pointer math into SlopSetViewPtr (shared by the camera + the warp landing). Verified: browse Pallet -> Route 1, A -> player lands on Route 1 at the centre tile and walks around normally (sprite + Pikachu, wild data intact). 2026-07-15T11:58:35Z Ash Ketchum no-reply@sl0p.foo 2026-07-15T11:58:35Z urn:sha1:76925904c16bef43eea7d8d08f864880695525fd Overlay real ▲▼◀▶ arrow sprites at the screen edges for every direction the camera can currently page: either there's more map that way, or the map has a connection that way. Arrows update live -- e.g. at a connectionless edge that direction's arrow disappears. Implementation: the font has only a down-arrow ($ee) and right-arrow ($ed), so up/left are made with CGB OBJ Y/X-flip (the emulator supports OBJ flips). Drawn as 4 sprites in wShadowOAM (8x8 OBJ mode, font loaded so $ed/$ee are OBJ- reachable at 0x8ed0/0x8ee0). Set wUpdateSpritesEnabled=$ff after building them so the vblank PrepareOAMData leaves shadow OAM alone instead of repopulating the player sprite over the arrows. Verified: Pallet mid-map shows all 4; Viridian shows N/S/W (no E); paging to a connectionless edge drops that arrow and it returns on the way back. 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.
