* Update crt-royale-fast and several presets - Presets moved to new folder presets/crt-royale/fast. - New presets for 1080p and 4k. - Slotmask updated. * Update crt-royale-fast presets - Now all presets are full-fat. - Moved crt-royale-fast-ntsc-composite.slangp ro presets folder. * Final update to crt-royale-fast presets Added specifica genesis-rainbow-effect preset. It's only useful for a bunch of games. Standard genesis preset is better for most games.
