Project EGG has been around for years now. I have the Valis Collection somewhere. It's ports of the 4 PCE versions, plus some extra goodies. I'll take some pics later if I can find it.
Bam!Fun fact, while this collection uses the dreaded StarForce copy protection system, once the games are installed they do not require the disc to run. Meaning you can remove the StarForce crap completely and still play the games with no restrictions. ROLF. They are just 1:1 PCE ports though. Would have been nice if they had included other versions of the games for completeness sake.Sadly Project EGG stopped doing box releases a few years ago as they simply didn't sell well enough, now everything is just digital downloads. So yes, PC-98 Valis is now available, but download only.
