Keyboard & mouse

Default keyboard joystick mapping: arrow keys move, Left Ctrl fires and Space sends the original Space key. Original game keys remain available.

These are release defaults, not your saved remaps. Open F11 → Controls for this game for live mappings, or F12 → Controls to change them. Start and Back remain reserved for SemaTor menus. Mouse speed is adjustable. One active host gamepad is supported; two-player modes do not imply two simultaneous gamepads.

Verified editions & checksums

These are the exact identities used by the enhanced profiles in SemaTor 1.1.320. A recognised profile is not a promise that every level, option or graphics device has been tested.

Exact supplied profile edition. Its supplied gameplay log exposed a Vulkan allocation failure, fixed in 1.1.320. The live checkpoint save/preview/reload test also passes and resumes gameplay. Physical NVIDIA validation of the reported crash remains outstanding.

Program SHA-1 covers the raw executable text before relocation, excluding its file header. Boot SHA-1 covers the decoded 512-byte boot sector. Neither is the checksum of the whole PRG, STX or ZIP. SemaTor’s library problem-report draft includes the executable SHA-1 and whether it is exactly recognised.

Download the edition/checksum list. If your edition is different, report its identity before assuming its enhanced profile is compatible.

OPTIONS BY EDITION

Make it your game.

Names match the release profiles, including experimental and practice options. Availability depends on the recognised disk edition. A matching filename alone does not verify an edition; untested releases may behave differently.

Playing on Android or Thor?

Android and dual-screen controls remain in testing. Touch layouts can differ from desktop gamepad defaults. Mega lo Mania’s Thor panel and direct-touch input need device validation; this guide does not certify every touch layout.
