PC PORT UPDATE: With the decompilation of (Saturn) Sonic 3D Blast in fairly good shape, I took some time to work on the native PC port. This PC port is based on the decompilation project that I've been grinding on for the past few months. It's already in great shape, and is FAR better than my earlier (and hilariously buggy) first attempt at a re-implementation. I can safely say that this will be an accurate and faithful port. Even now, all of the attract sequences play exactly like they do on the Saturn. Gameplay footage of the first level / act is below. Some notes: - Absolutely zero emulation is being done here - this is a fully native PC port based on decompiled source code. - The source code for this new port is built in C, with SDL to handle window management, input, timing, audio, etc. For the sake of accuracy, the graphics are software-rendered, but use OpenGL to draw the final framebuffer and handle screen shaders. - Widescreen aspect ratios are supported. This works great for the most part right now, with HUD elements being correctly positioned, tile scrolling working correctly, entity sprites not being horizonally-culled, etc. There are some minor fixable issues (e.g. level title cards and pause screen are showing some garbage on the screen edges). Some things remain centered in 4:3, such as the FMV videos and title screen. - Special Stages are in great shape, with a few minor visual issues to fix, such as visible seams on polygon edges. On the Saturn version, the Special Stage engine was originally coded in SH2 assembly, but has been converted to C for this port. These Special Stages originally ran at a locked 30fps, but I've included an option to allow for higher framerates (via interpolation). - In this port, pressing the gamepad's SELECT button (or F1 on the keyboard) opens up a special options menu to allow the player to change some settings, like aspect ratio, screen filter, etc. This menu will be expanded with more options. - All game assets are loaded directly from the original game disc files (which the user must supply). Any of the three releases (US, EU, JP) are supported. My goal is to release the first version of this PC port on 11/20/2026, on the 30th anniversary of when this game came out for the Saturn in the US (11/20/1996).

BIG UPDATE: Holy shit, decomp progress (for the Saturn version of Sonic 3D Blast) is at 100% now! What's left to do: - Add support for all three releases of the game (NTSC-U, PAL, NTSC-J) - Currently only the US release is supported. - Clean up, fully document the code and ensure it's as human-readable as it can be, while ensuring it remains 100% matching / byte-exact. - Produce a faithful native PC port based on the decomp. Source code for the decomp and PC port (with playable binaries) will be released on GitHub when this is all done. This may take some time.
