Standalone emulator for early Gaelco 3D games.
Enclosed is the source code for my standalone Gaelco 3D game emulator. It is kind of a quick and dirty implementation, but the key aspects are static high level emulation of the TMS32031 and ADSP2100.
Previously, only the Radikal Bikers emulator has been released. However, I had done some work on Surf Planet and Speed Up as well.
The code has been built from the command line using Visual Studio 2008 tools on a Windows machine running Windows 8.1. The two-letter batch files at the root of the project show how to invoke nmake.
The current status of each game is as follows:
-
Radikal Bikers: ADSP2100 and TMS32031 are both emulated with C code for maximum speed. As I recall there were some occasional glitches present, but overall it runs pretty well with full sound.
-
Surf Planet and Speed Up: both the ADSP2100 and TMS32031 emulations are copied from Radikal Bikers and don't work. They would need to be reimplemented based on analyzing the game-specific code. This means sound doesn't work in either game. For the TMS32031, the C code has been disabled with a fallback to running the TMS32031 through a slow interpreter. Thus, the games boot up and run, but not particularly fast. No effort has been made to map the controls.
When run full-screen, all games render their graphics at the full screen resolution. When run in a window, games run at their native resolution. FPS display can be seen in the title bar of the window.
