Hello everybody, I think it's time to give a news update for the SNES emu on SEGA Saturn:
The development of this emu has been continued, indeed! A lot of things have been done to speed the emu up. I wrote a homebrew Saturn library (SGL replacement), ported the assembler cpu core from DreamSNES (Dreamcast) over to SEGA Saturn, optimized compile flags and emulator settings as well as the usage of Saturn's RAM and so on.... And I did a lot of benchmarking which showed me that now, the emu is between 2 times and 3 times as fast as before!
It is still far from being fullspeed, but with frameskip most homebrew SNES demos are playable and some commercial ROMs have the potential to become playable, too. The thing that slows down the emu most is graphics rendering. If I could use Saturn's video hardware chips to render the graphics, or the slave cpu, then we could really play some SNES games on Saturn!
Apart from speeding up the GFX rendering, the things that I could do is increasing the compatibility of the asm cpu core and maybe get it working with a 1MB cart or even no cart (unlikely to happen), too.
The emu is still not released, but I'm about to send the latest version to some testers.
