fix: resolve bios case collisions

Delete duplicate lowercase variants (identical MD5) of 12 files that prevented clean checkout on case-insensitive filesystems (Windows, macOS). Canonical chosen per upstream source code: - Atari 2600 KV*.WAV: uppercase (stella2023 hardcode) - Vectrex VEC_Minestorm.vec: lowercase (BizHawk hardcode) - MSX MSX{,2,2EXT}.ROM: uppercase (fMSX hardcode, 6/7 platforms) - Doom DOOM2.WAD: uppercase (matches dir convention) Add aliases to stella2014 and clk profiles so resolution still finds the canonical source. Correct retrodeck Vectrex casing to match upstream. Merge Commodore/Vic-20 into VIC-20. Add tests/test_no_case_collisions.py as a CI guard. Closes #49

Abdessamad Derraz	e90095abd9	fix: resolve bios case collisions Delete duplicate lowercase variants (identical MD5) of 12 files that prevented clean checkout on case-insensitive filesystems (Windows, macOS). Canonical chosen per upstream source code: - Atari 2600 KV*.WAV: uppercase (stella2023 hardcode) - Vectrex VEC_Minestorm.vec: lowercase (BizHawk hardcode) - MSX MSX{,2,2EXT}.ROM: uppercase (fMSX hardcode, 6/7 platforms) - Doom DOOM2.WAD: uppercase (matches dir convention) Add aliases to stella2014 and clk profiles so resolution still finds the canonical source. Correct retrodeck Vectrex casing to match upstream. Merge Commodore/Vic-20 into VIC-20. Add tests/test_no_case_collisions.py as a CI guard. Closes #49	2026-04-18 10:01:29 +02:00
