General Jo Engine Help / Megadrive to Saturn
« on: July 18, 2017, 03:35:00 am »
I program on the Sega Megadrive and its addons, in Motorola 68000 Assembly, and I'm looking for a way to try, perhaps port my game(s) to the Saturn.
I don't dominate C, I handle a few basics (so far I can write my own format converters in win32). After seeing the Sonic demo, I got an idea. Work the Saturn the same way as Sonic 3D Blast!. Write an ASM2C kind of tool, to port the objects' physics, and let the SDK (Jo Engine here) handle all the I/O!. I don't think porting certain libraries such as the scroll, object refresh or collision engines would be necessary, unless the gameplay begins to differ too much.
... unless... is it possible to use the 68000 for the core engine processing, and leave both SH2 with the video renderer and sound mixer? This is the way Knuckles' Chaotix and my current project are set up, in Sega 32x.
Where could I, or how should I begin?
I'm looking for a way that ensures (or gets close to) a smooth lagless play, probably with stable/trustable compatiblity between different emulators and hardware.
Thanks
