An 82-byte payload written in GSPA assembly, linked at bit 01800000h and loaded into main RAM by harness/mame/hello.lua, executes on the CPU: it writes DEAD/BEEF and a 1024-iteration counter into RAM and fills a 256x64 block in video RAM, which appears in the frame dump at x 256..511, y 136..199. Entry is a debugger breakpoint on the level-0 menu idle loop, not a delivery mechanism. Includes the build script, a COFF .text extractor (gsprom's hex addresses wrap at 64 KB), the run log, RAM excerpt, frame crops including a no-load control, and HELLO_WORLD_REPORT.md.
