1. Bilinear Filtering
The PC CD-ROM version of Breath of Fire IV employs a forced bilinear filter on the game’s 2D sprites and 3D environments that is not present in the PlayStation version. This results in blurred, smoothed-out 2D sprites and smoothed-out 3D textures.
Solution: The bilinear filter in the PC version can be overridden by using an external program such as dgVoodoo2 to enforce point-filtering, achieving a more pixel art-look akin to the PlayStation version.
Request: GOG should update the DirectX wrapper to allow you to force point sampling for a pixel look.
2. 3D Environments and Models
3D environments and 3D models are rendered at a higher resolution in the PC version of Breath of Fire IV, resulting in a smoother look with less jagged edges. Nevertheless, clipping issues occur between the models and the geometry. i.e. Aura Dragon's right claw clips through the crater in an early cutscene, and Khafu's wing clips through the cliffside during the boss fight as Fou-Lu.
Also, seams in the subdivided 3D polygonal terrain are much more visible in the PC version.
Request: Update collision of 3D models to avoid clipping and be closer to the PS1 version. Mask the seams in the 3D blocked terrain.
3. Text/Font
The PS1 version's pixel font was replaced with a chunkier font reminiscent of Denver Serial.
Request: It'd be great to be able to switch between the classic font and the 2003 PC font.
4. Music Comparison
The PlayStation version of the BGM (background music) employs a reverb effect to make it sound fuller. The PC version of the music has the reverb effect removed, resulting in a flatter sound, especially with brass instruments.
Request: Update the BGM with the PS1 version's.
5. Incorrect Looping of BGM
In the PlayStation version of the game, BGM loops properly. In the PC version, when a track reaches its end, the music abruptly restarts from the beginning without a proper, seamless loop.
Request: Fix the music looping bug so that music seamlessly loops.
6. Missing Boss Victory Themes
Breath of Fire IV has two victory theme melodies that play depending on which continent you’re battling in:
Eastern Continent Victory Theme: “To the Victor Go the Spoils (2000 Edition)”
Western Continent Victory Theme: “Take The Money & Run”
In the PlayStation version, upon defeating a boss, alternative, more triumphant-sounding versions of these two victory themes play. These versions are absent in the PC release, with the normal victory themes playing instead.
Request: Bring back the PS1 version's unique boss victory theme variations.
7. Removed & Edited Cutscenes
The deleted scenes in Checkpoint, Shikk, Saldine, and the Castle from the North American and European PlayStation version remain removed in the English PC release.
Request: Restore these cutscenes in the English release since they still exist in the Japanese version.
8. Dengeki Shop
The Dengeki Shop south of Mt. Glom was removed from the Japanese PC release of Breath of Fire IV: Utsurowazaru Mono and is not present in any other PC version.
Request: Restore the Dengeki Shop in all versions.
9. Remapping Camera Turn Left and Right to L1/R1 aka LB/RB results in the camera turning not working.
In the PS1 version, camera turning was bound to the shoulder buttons, not the triggers. Meanwhile Change Rank was L2/R2 (triggers). Ideally, you should be able to reverse these and bind them like they were in the PS1 version.
Request: Allow Camera Left and Camera Right to work with L1/R1 and Change Rank to work with both L2/R2.
10. On-screen command prompts show keyboard keys even when using a controller.
Request: Replace on-screen keyboard key prompts with appropriate buttons depending on the controller connected (PS/Xbox/NSW).
11. Windowed Mode doesn't work and displays like Fullscreen.
