HD Graphics Renderer for MAME Arcade Game

C++ / MAME Developer Needed for HD Graphics Renderer for Classic Arcade Game.

We are developing an HD visual remaster system for Atari game running through a custom MAME build. The goal is to preserve the original game logic, controls, physics, collision detection, timing and level layout while replacing/upgrading the visual presentation.

We already have a custom MAME 0.281 build compiling successfully, RGB32 rendering working, access to the scrolling 128×64 tilemap/world coordinates, a Lua world-mapping tool, and several working proof-of-concept builds.

We need an experienced C++ graphics/emulation developer to help implement a robust world-aligned replacement rendering system capable of displaying new high-resolution environmental artwork in place of the original 8×8 tile-based graphics while preserving original sprites/game behavior where required.

Experience with MAME internals, C++, tilemaps, sprite compositing, 2D rendering, texture atlases, OpenGL/BGFX/SDL, emulator development or HD texture replacement systems is highly desirable.
