E-SRG for Vectrex

Game design is mine but the implementation is Claude Opus 5.5 Using libraries and documentation from: https://github.com/malbanGit/Vide https://github.com/tullulah/vectrex-s... Available here: https://github.com/emmulator/vectrex-... There are two files, but they only differ in initial calibration. 'v' is more likely to work well on a Vectrex. 'e' is more likely to work well in an emulator. Any version can be calibrated by holding '4'.
