Game Description:
A massive improvement patch for the Saturn's version of Doom that turns what is a sad footnote of a port into something that is not only playable, but actually enjoyable by improving performance and fixing bugs.
Author(s): fafling
Type: Bugfix, Improvement
Version: 0.3
Date: 11th of May, 2026
Status: Fully Playable

Changelog:
Spoiler ▶- Startup :
- Boot sector program IP.BIN made region free and updated with patch version and date.
- Adds a sound effect when interrupting the logo sequence by pressing start (same sound effect than when pressing start on the title screen).
- Controls :
- Restores weapon bidirectional cycling, including during pause, while keeping the rollover that the Saturn commercial version introduced. Weapon cycle is inverted when maintaining the use button while pressing the cycle weapon button.
- The interval during which the chainsaw is going up no longer prevents any weapon cycling (problem present in the PSX version).
- Status bar : adds slot 0 in the weapon indicators of the status bar for the fist. This slot's number turns red to indicate a berserk condition.
- Performance : noticeably improves framerate again. It's now smooth in the simpler levels, but it can still go quite down in the more complex ones.
- Graphics : fixes additionnal gaps in graphics present in the PSX version (missing wall columns, rare missing sectors).
- Flats :
- Removes 2 pixels expansions that made the sides of ground or ceiling sectors overlap with walls (problem present in the PSX version). It reveals a few remaining gaps but it looks much better overall.
- Improves the precision of the low detail flats with high detail limits that were introduced in v0.2 to improve performance.
- Walls :
- Fixes last wall texture column being always replaced by the 2nd one (bug introduced by the Saturn commercial version in the workaround for texture repetition, see below).
- Wall textures are no longer stretched on walls higher than 256 pixels (problem present in the PSX version). They can now repeat over walls of up to 384 pixels, with a horizontal offset of one column every 128 pixels. That offset was present in the Saturn commercial version and it won't be fixed, otherwise it would hurt performance (VDP1 can't repeat a texture so texture length is extended when needed to following columns as a workaround, causing those offsets).
- Fixes the horizontal sliding of wall textures when viewed at an angle (bug present in the PSX version).
- Fixes incorrect diminishing light shading on walls that are partially hidden by another wall on their left (bug present in the PSX version).
- Automap :
- Removes status bar stats flicker when the map is toggled.
- Damage and item pick up color effects now work on the black background, not only on map lines. The color effects working on the automap was an improvement of the Saturn commercial version over the PSX version.
- General : restores some error checks (all had been disabled in the Saturn commercial version), but with a handling that is faster and doesn't crash the game unlike the PSX version, so for example a sector won't be rendered and the reason will be displayed by a message (I have yet to see one without forcing it with code modification).
- Patch bugfix :
- Fixes inversion between odd and even lines of animated wall textures (bug introduced in v0.2).
- Fixes rare vertical one line shakes of the status bar (bug introduced in v0.2).
- Fixes artifacts on the side of the screen when returning to the title screen from a demo or a level (bug introduced in v0.2).
What to do with multiple .bin "Track" files?
