📝 Wrote a post about the various strategies of porting PC-98 Touhou to modern platforms! Also clears up common misconceptions about the performance of the PC-98 originals. This one is required reading for anyone who wants to see these games ported. Link: rec98.nmlgc.net/blog/2025-09-06

Many thanks to this month's subscribers! Code is done escalating, and now it's the blog post's turn. Got >13,000 words now and it's still missing lots of content… I'll be so relieved once I get to spend the rest of the year on TH03 and Shuusou Gyoku with no more distractions.
