Once it's all setup and done, it should be fairly easy to port to SH3. But give the man some time and let him finish a SH4 version first
I mean, this project just took off a couple of weeks or so ago. In all the years of SH3/SH4 this has never been attempted (and/or considered impossible), and now we already want him to release it for both games and all sub sections? :rotfl:
Keep in mind, it's a huge undertaking that he and the other participants are doing. The screenshots are very promising, but with the talent around, it's not nearly close of what's to come in the future of this game. I can assure you that.
They have only just begun experimenting. Just give it some time, and keep encouraging them.
Nice job so far, guys! I'm proud of you! This is exactly why I love making S3D
