ewrogersmegadev-best-practices
Apply Megadev-specific C/assembly, project-structure and integration practices while preserving CPU, interrupt and resource ownership. Use when writing or reviewing Megadev game code, joining existing systems, or fixing cross-system correctness problems; detailed graphics, audio, loading, save and release implementations remain with their own skills.

ewrogersmegadev-combat
Implement attack resolution, directional guards, damage, invulnerability and knockback in Megadev Sega CD games. Use for combat rule ordering, attack-instance hit tracking and bounded projectile handling; animation timing, geometry and enemy decisions remain separate concerns.

ewrogersmegadev-graphics
Render scrolling planes, parallax, sprites, animation frames and palette effects in Megadev Sega CD/Mega CD projects. Use for VDP layout, display priority, sprite budgets and frame submission; asset conversion and disc-streaming policy are separate concerns.

ewrogersmegadev-hardware
Investigate and validate Sega CD/Mega CD hardware behavior in a Megadev project, including CPU-specific memory maps, Word RAM ownership, BIOS services and hardware test evidence. Use for hardware assumptions and diagnostics rather than game design or SGDK API guidance.

ewrogersmegadev-input
Integrate 3/6-button pads, Mega Mouse and Sega/EA multitaps into Megadev Sega CD/Mega CD projects, with verified SDK boundaries, bounded protocol readers and stable input snapshots. Use for device polling, input edges/repeat, socket identity and controller testing rather than game-specific controls.

ewrogersmegadev-levels
Build authored Megadev Sega CD/Mega CD areas from Tiled maps, with separate collision layers, camera bounds, scrolling tile caches and named connected exits. Use for map import/runtime integration and level residency, rather than a general physics engine or genre-specific game rules.

ewrogersmegadev-localization
Prepare Megadev Sega CD games for translated text with stable message IDs, accented glyphs, font budgets, safe substitutions and translated layout checks. Use for multilingual UI, dialogue and language preferences rather than general text rendering alone.

ewrogersmegadev-math
Choose and validate fixed-point formats, vectors, trig and interpolation for Megadev on the original Mega CD 68000 CPUs. Use for fractional movement, direction normalization, rotations, easing, overflow or numeric-range bugs; includes a standalone Math Lab and executable checks.

ewrogersmegadev-scaling
Build and diagnose Sega CD graphics ASIC rotation, scaling and perspective floors in Megadev, covering stamp maps, per-line trace vectors, 2M Word RAM ownership, completion and bounded VDP uploads. Use for the ASIC path rather than ordinary VDP sprite animation or software-only 3D.

ewrogerssgdk-ai
Implement enemy behavior in SGDK games with patrol/chase/attack states, sight cones, target selection, bounded pathfinding and staggered updates. Use when enemies see through walls, get stuck, switch targets erratically, return stale paths or cause frame spikes while searching.

ewrogerssgdk-assets
Prepare, import and troubleshoot Mega Drive graphics, palettes, spritesheets, tiles, maps, fonts and audio resources with SGDK ResComp in Docker. Use for .res files, palette or tile budgets, broken imports, sprite cutting and asset pipeline changes.

ewrogerssgdk-best-practices
Write or review SGDK C for defined arithmetic, clear module boundaries, resource lifetimes, safe queued transfers and interrupt sharing. Use for implementation quality and project code organization, rather than toolchain setup, game design or performance profiling alone.

ewrogerssgdk-cartridge
Plan and implement large SGDK cartridges with Sega/SSF bank switching, FAR resources, pinned shared code and audio, and safe SRAM access. Use when a ROM exceeds the linear address window, stage assets live in separate banks, a FAR pointer becomes invalid, or saving interferes with banked content.
