I started but it became apparent that it might be easier to just re-draw them from scratch rather than try a direct conversion. They are really simple anyway, at least the first game is. Most of the levels could be drawn with a couple hundred polygons and 1 VDP2 infinite plane.
Did you use any tools to make the conversion easier or did you draw them from scratch? One thing I actually found hard on PS1 stuff is there seems to be almost no homebrew scene - or at least it's even more obscure than the Saturn homebrew scene. I could have just been looking in the wrong places?
I did find the "Twisted Toolkit" which can export models and textures, and I did use that somewhat - but it was pretty buggy and crashed a lot, and I couldn't find a good way to convert the exported models into a Saturn format (maybe I need to try Blender again).

Hello there!
I am progressing well on the second level of MGS
and I'm wondering if anyone has an idea for a VDP2's compatible solution that would use 1 or 2 layers (I want to keep one for the background) to achieve a snow effect equivalent to the particle system used in the PS1 version:
It doesn't need to be close or similar, just something that looks like falling snow in a cycle without generating too many calculations or consuming too much memory.
So if you have any ideas or can think of any Saturn/PS1 games with snow effects, I'm all ears.

what background layers do you have available? you should be able to use slColorCalc() with CC_ADD (or CC_RATE, but I think _ADD will look better) on any BG layer that is available, and then scroll it. you could even do 2 layers and scroll them in different directions, which would be closer to what MGS looks like.

Thanks for your suggestion guys
16x16 tiles dynamically animated by changing palette seems a good way to achieve a non-rainy snow effect. To avoid too much repetition, maybe 4 differents tiles will be necessary and to break the up/down-line effect, a scrolling on X/Y at the same time

The snow effect from FF6 intro looks great
More simple but not bad, the snow effect in Super Adventure Island II
Not a big fan but Sonic 3 has also a snow effect
These all look like they use sprites. an option for sure, but you will use up more fill rate an CPU that way.
