Hello! Do any of my followers happen to have a copy of Sega Force #15 (March 1993) that they could sell or provide some high res scans of a couple pages? Please let me know!

Working on the next example project for Megadev which shows how to use the Mega CD's hardware scaling/rotation. Took a little while to figure it out, but I think I have a handle on it now...

One of the wildest parts of Raimais is the hidden ending, folks had discovered voice samples that alluded to it but it was @sudden-desu.net who figured out how to access it, since the requirements to reach it were either disabled or nearly impossible to reach sudden-desu.net/entry/raimai...

The developer Hertz was making a golf game for the Mega CD (Polygon Golf), so it's possible. bsky.app/profile/emot...
I’m not prone to tin foil hat thinking but you will never convince me that the overworked maps in Vay were not repurposed from someone’s pet golf game that got canned early in design.
The way these scan at first glance reminds me of how Vay for the Mega CD has a bunch of world maps that look like they started as someone’s sketches for golf courses, sand traps and all.

I still want to know about the music track used on the trailer packed with Parasite Eve since it wasn't in the final game and was never heard again. Is it Uematsu? Does it have a title? Can we ever hear a HQ recording?
