Japanese nationals in the 90s?

Hey everyone.
Been looking abit into the japanese scene in the 90s and im looking for some information to fill in a few gaps.

I know that Japan ran these national tournaments:
92. Gamest Cup SF2:CE & Capcom SNES World Warrior Championship 92’
93. Capcom SNES Hyper Championship 93’
94. Gamest Cup SSF2T & Capcom SNES Super Championship 94’
95. Gamest Cup Vampire Hunter
96.
97. Gamest Cup Vampire Savior
98. Alpha 3 Nationals
99. Alpha 3 Nationals

Questions i have that hopefully someone old school can remember.
1.) Did Gamest have a Cup during 1993? and if so what game did they run that year?
2.) Did Gamest only run a single game each year?
3.) What national happend during 1996? (was that the Alpha 2 championships?)
4.) Was there any other national championships for other games during this period? or does japan just run a single CAPCOM game to crown a national champion each year?
5.) And lastly, was the Alpha3 nationals also hosted by GAMEST magazine in 98/99

Thanks.
