Looking forward to this (as this is my all time favourite MSX game), and wondering which techniques are used and which changes are made. Only graphics? Music enhancements? Screen 4? (I didn't find any teaser.)
From what I remember (interview with Toni Galvez, who is making the graphics, in Spanish: https://youtu.be/_KdS-ijO7dU?t=8849 ), they are remaking graphics using screen 5 and also music/SFX. Toni also mentioned that they are using 2 sprites per enemy in order to have more colors there.
OK, I wonder if they manage to realize the same speed as the original!
I don't think speed should be an issue. Screen 5 have double sprites, so player and enemies will have double of them. Only underwater monsters looks like GFX sprites, but those don't need much speed to copy small amounts of VRAM data per frame. So speed should be exactly the same or even better.
Also music will be remade from PSG to SCC. So it should feel like a solid Konami MSX2 game. I hope they will make screen 5 Konami logo for it too to complete the transformation.
I would keep PSG music as well and let player to choose between PSG or SCC. Because original soundtrack is classic.
