Saved some of my best and weirdest hacks for last!
STARGAZER HYDLIDE - a mashup of Hydlide Special and Hosh Wo Miru Hito
BOSS TEST 255 LIVES - a hack of a shockingly amazing Famicom BASIC shooter boss simulator (hence the title) created by legendary shooter game designer Yosshin during his 1980s shareware days.
NAUSICAA MUSIC PLAYER - A hack of Galaxian Famicom which turns it into a music box that plays the Requiem Theme from Nausicaa and the Valley of the Wind.
RED ARIYAMA ADVENTURE - a graphics and gameplay upgrade to the 1980s shareware Famicom BASIC game Red Ariyama.
ARKISTA'S RING FONT UPGRADE - updates the ugly font to a high fantasy one, but also includes all the graphics and game play changes from the hack I posted on Ko-Fi. So a multi-faceted upgrade of the game.
