GAME GUIDE / 1.1.320
Arkanoid II: Revenge of Doh
Original game enhancements and an optional native 21:9 campaign.
Xorg Unbound
The optional widescreen campaign is launched from the F12 home page. It is distinct from the original game; the controller guide below describes original-game defaults. Follow the campaign’s on-screen selection prompts.
SEMATOR CONTROL DECK
Your controls, at a glance.
Mouse moves the paddle; left click launches / fires. Space starts the verified original edition. Xorg Unbound also accepts the normal campaign pad controls.
Select a button to see its action.

Keyboard & mouse
Mouse: move the pointer; left click selects; right click is available where the game uses it. Space starts the verified original edition.
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.
The supplied original Imagine disk contains an AUTO helper before DOH.PRG. 1.1.320 selects the verified game loader. A 160-million-instruction run reached the game, with 2,530 exact reconstructed frames, live sprite/audio guards accepted and no CPU fault. Later rounds and complete-game completion are not certified.

Compare the extracted .st or .stx file, not its ZIP. Windows PowerShell: Get-FileHash -Algorithm SHA256 "your-disk.stx". Linux: sha256sum "your-disk.stx". A different disk hash may still contain a supported program; use the profile identities below.

|---|---|---|
| Arkanoid II: Revenge of Doh (1988, Imagine) DOH.PRG | raw program-text SHA-15b6e577149dbdd36973af1df191c9412d9156030 | 2658 |

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.
