I.N.E.R.T.I.A. for SVI-318
Recently I ported my old MSX game I.N.E.R.T.I.A. to SVI-318, a sort of pre-MSX machine; I believe there's some lack of titles for it, especially in ROM format.
Believe it or not: no, I don't own an SVI-318! I tested the ROM on BlueMSX 2.8.2.
I had some difficulties in the porting process because SVI BIOS turned out to be less comprehensive than MSX, but in the end I could produce a working ROM.
Download the full package containing the ROM game (inertia_svi.rom), the C sources that I compiled with SDCC, and a nice typesetted manual (doc/manual.pdf). If you are proficient at C programming, feel free to have a look at the sources and improve them in the future to the benefit of other SVI users :-).
