In advent of Raiden X, Strikers 1945, R-Type, and Reginald Nowe's Gradius clone; It's high time to remake some lesser-known games:
1. Thunder Force: The Thunder Force series started on Sharp and NEC's PCs in 1983 as a Xevious-meets-Vanguard II game. Due to the fact that Technosoft had no experience with NES or SMS hardware; It was never ported to either one of those systems. This was corrected with TFII for the Sharp X68000 and the Sega Genesis. The Link has more info than I can write.

2. Darius: Not many people know about this, but just look for "Darius (Arcade Game)" on wikipedia if you want to know.
