Originally, Success Corp. was going to release Sanvien as a Taito G-Card cartridge to be played on the Taito G-Net arcade motherboard platform but decided to release Psyvariar Medium Unit instead to the Japanese game centers in March of 2000. Both games of Psy-MU and Sanvien were in production/development at the same time with majority of the BGM tunes on both games done by WASi303 himself. It certainly would've been cool if Sanvien was released properly as a G-Net title. Quite an impressive continue countdown timer with the slick graphical touches that no other game has indeed.
So all that work into creating Sanvien was not lost/gone up in smoke, as it was decided that it'd be best to release it on the PSX platform (considering that the original coding was for the G-Net hardware which is souped-up PSX 1.5 version hardware anyways). Still better than not having it released at all and for it to remain as a prototype "vaporware" game at best.
The original JPN PSX release of Sanvien still has the joystick control shown during the demo scene to show that it was, indeed, going to be an bona-fide G-Net arcade release. The USA PSX release of Starfighter Sanvien from Agetech (under it's budget "A1 Games" label division), omitted the joystick portion during the game demo scenes though.
Sanvien sure had some cool touches, especially with the staff ending credits with some in-game graphics shown as it scrolls on by.
