NASU (SEGA Genesis/Mega Drive remake)
This is exactly what it says on the banner. I was going to remake the entire game for this dead but beloved platform but it turned out to be too ambitious a project for someone with barely any knowledge of C. However, it wasn't a waste of time since I at least managed to complete NASU, objectively the most important part of Yume Nikki.
You can probably figure out the controls yourself, but if you repeatedly press C in the title screen you can cycle through the entire YN soundtrack, arranged by me, until it goes silent or crashes.
High scores will only be saved for the session because I could never figure out how to get SRAM working.
Big thanks to Grind for helping me with gendev back in the day (even though I got nowhere with that) and the people behind SGDK!
The game running in Genesis Plus GX (libretro).
